Optimized method for dna extraction and PCR amplification in aroeira tree

Molecular markers are important tools in the characterization of plant genetic diversity and can provide support for conservation strategies for endangered populations. The different molecular techniques involve the evaluation of many individuals; therefore, it is crucial to have fast, efficient, and inexpensive methods for DNA extraction. Given the importance of the Aroeira (Myracrodruon urundeuva Fr. All.) it is pertinent to optimize a protocol that allows the obtainment of intact and pure DNA, aiming to assist conservation strategies for this species that is threatened with extinction. Thus, this study aimed to compare five DNA extraction methods: Dellaporta et al. (1983), Doyle and Doyle (1987) modified, Ferreira and Grattapaglia (1995), Romano and Brasileiro (2015), and Khanuja et al. (1999) and optimize the most efficient protocol for M. urundeuva. The modified DNA extraction protocol proposed by Doyle and Doyle (1987), using 100 mg of leaf tissue and 6 µl of ß-mercaptoethanol was the protocol that presented the sharpest bands after DNA electrophoresis and after the reactions of amplification employing Polymerase Chain Reaction (PCR). Therefore, it is suggested to use the protocol described by Doyle and Doyle (1987) modified for the extraction of DNA from young M. urundeuva leaves to carry out techniques involving molecular markers.

High-intensity resistance exercise and Schinus terenbinthifolius supplementation attenuate oxidative stress and muscle damage biomarkers / El ejercicio de resistencia de alta intensidad y la suplementación con Schinus terenbinthifolius atenúan los biomarcadores del estrés oxidativo y daño muscular

SUMMARY: High-intensity physical exercises can cause oxidative stress and muscle damage. Several medicinal plants have been used as antioxidant and anti-inflammatory agents. The present study evaluated high-intensity resistance exercise (HIRE) associated with Schinus Terebentifholius ethanolic extract (EE) on oxidative parameters and muscle damage in Wistar rats. Animals were divided into 04 groups (n=10/group): 1. Control (CG) - animals that did not undergo HIRE and were treated with vehicle (distilled water, orally); 2. Acute exercise (AE) - animals submitted to acute exercise session; 3. Exercise + vehicle (EV) - animals that underwent HIRE and were treated with vehicle and 4. Exercise + extract (EX) animals administered with Schinus terebenthifolius EE (100mg/Kg, orally) and submitted to the exercise session. Schinus terebenthifolius EE showed high in vitro antioxidant activity (13.88 ± 0.36 mg/mL). Before the experimental period, lactate was measured at pre and post moments of AE (p<0.0001) and EX (p<0.0001) groups. After the acute session, the following were evaluated: oxidative stress {malondialdehyde (MDA), sulfhydryl groups (SH) and ferric reducing antioxidant power (FRAP)}, muscle damage (creatine kinase (CK) and lactate dehydrogenase (LDH)), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). In the in vivo analyses of the EX group compared to AE and EV groups, respectively: hepatic (MDA: p<0.0001 and SH: p=0.0033, in both; FRAP: p=0.0011 and p=0.0047), muscle (MDA, SH and FRAP: p<0.0001, in both; CK: p=0.0001 and p<0.0001; LDH: p<0.0001, in both), serum levels (MDA: p=0.0003, p=0.0012, SH: p=0.0056, p=0.0200, FRAP: p=0.0017 and p=0.0165) were significant. There was no significant difference in ALT and AST markers. It could be concluded that Schinus terebenthifolius EE associated with HIRE attenuated oxidative stress and muscle damage in rats.

En los análisis in vivo del grupo EX frente a los grupos AE y EV, respectivamente: hepático (MDA: p<0,0001 y SH: p=0,0033, en ambos; FRAP: p=0,0011 y p=0,0047), muscular (MDA, SH y FRAP: p<0,0001, en ambos; CK: p=0,0001 y p<0,0001; LDH: p<0,0001, en ambos), niveles séricos (MDA: p=0,0003, p=0,0012, SH: p=0,0056, p=0,0200, FRAP: p=0,0017 y p=0,0165) fueron significativas. No hubo diferencia significativa en los marcadores ALT y AST. Se podría concluir que Schinus terebenthifolius EE asociado con HIRE atenuó el estrés oxidativo y el daño muscular en ratas.

Bioactive phenolic compounds and organic acids in the decoction of fruits and leaves of Schinus areira L / Compuestos fenólicos bioactivos y ácidos orgánicos en la decocción de frutos y hojas de Schinus areira L

Leaf and fruit decoctions of Schinus areira L. from northwest Argentina were investigated here. Phenolic compounds and organic acids were analyzed by HPLC. Antioxidant capacity and α-glucosidase inhibition were determined by using in vitro tests. The general toxicity was assessed against Artemia salina nauplii. Hyperoside and 3 O-caffeoylquinic acid in leaf decoctions; gallic acid and catechin in fruit decoction were the major phenolic compounds. Malic and citric acids were the main organic acid quantified in the leaf and fruit decoctions, respectively. Fruit decoction had a relatively important content of shikimic acid, precursor of Tamiflu. Leaf decoction presents a greater richness in bioactive compounds with antiradical activity against DPPH●, O2●-and ●NO radicals. S. areira leaves and fruits had α-glucosidase inhibitory activity comparable to hyperoside and acarbose. Fruit decoction was not eco-toxic; leaf decoction showed significant eco-toxic activity and could be chosen for the search of other bioactive compounds with pharmacological activity.

Se investigaron decocciones de hojas y frutos de Schinus areira L. del noroeste de Argentina. Compuestos fenólicos y ácidos orgánicos se analizaron mediante HPLC. Capacidad antioxidante e inhibición de α-glucosidasa se determinaron in vitro. Se evaluó toxicidad general con Artemia salina. Los principales compuestos fenólicos fueron hiperósido y ácido 3 O-cafeoilquínico en hojas y ácido gálico y catequina en frutos. Los principales ácidos orgánicos cuantificados fueron málico en hojas y cítrico en frutos. Ácido shikímico, precursor del Tamiflu está presente en decocción de frutos con un contenido relativamente importante. La de hojas presenta una mayor riqueza en compuestos bioactivos con actividad antirradicalaria frente a DPPH●, O2●-y ●NO. Las hojas y frutos de S. areira tenían una actividad inhibidora de la α-glucosidasa comparable a la de hiperósido y acarbosa. La decocción de frutas no fue eco-tóxica, pero sí la de hojas que podría ser fuente de compuestos bioactivos con actividad farmacológica.

Extracts and purified substances of Cabralea canjerana inhibit hatching and extracts of Schinus terebinthifolius kill juveniles of meloidogyne incognita

Nematicidal substances have been identified from plants and are potentially useful for the management of plant-parasitic nematodes. Cabralea canjerana, (Meliaceae) and Schinus terebinthifolius (Anacardiaceae) produce bioactive compounds during their secondary metabolism and little is known about the effect of such substances on plant-parasitic nematodes. In the present study, we assessed the effect of aqueous and ethanolic extracts of C. canjerana and S. terebinthifolius at 1% (m:v) and purified substances from C. canjerana (gedunin, ocotillone, cabraleadiol, a mixture of ocotillone + cabraleadiol and a mixture of shoreic acid + eichlerianic acid) on hatching and mortality of Meloidogyne incognita juveniles. Aqueous extracts of C. canjerana fruits and seeds reduced hatching by 70.3 to 95.7%. Aqueous extracts of S. terebinthifolius fruits killed 42.8 to 77.1% of juveniles. The purified substances of C. canjerana inhibited the hatching of M. incognita from 57 to 90% and did not increase the mortality of juveniles. Therefore, C. canjerana extracts and its purified substances reduce M. incognita hatching and aqueous extracts of S. terebinthifolius kill J2 of this nematode.

Biological properties of Schinus terebinthifolia Raddi essential oil

Abstract Schinus terebinthifolia Raddi green fruits essential oil (EO) was evaluated regarding its phytochemical profile, antimicrobial and cytotoxic activities, and toxicity. Gas chromatography with mass spectrometry was applied to identify its constituents, thereafter the minimum inhibitory concentration, minimum bactericidal and fungicidal concentrations, and its antibiofilm activity were evaluated. The EO cytotoxicity was assessed in tumor and non-tumor human cells, and in vivo toxicity was evaluated in a Galleria mellonella model. The major constituents of S. terebinthifolia EO were alpha-phellandrene and beta-phellandrene. The EO had a weak activity against all strains of Candida albicans (MIC 1000µg/mL) and had no activity against non-albicans strains, bacteria, and C. albicans biofilm. Cytostatic activity against all tumor cell lines was shown. Additionally, cell viability remained at EO concentrations up to 62.5 µg/mL. At 16 mg/mL, 50% hemolysis was observed, and it had low toxicity in vivo. Overall, the S. terebinthifolia EO was characterized by low antimicrobial and antibiofilm activities, with no evidence of toxicity to human tumor and non-tumor cells

Viabilidade de sementes de espécies forrageiras com tratamentos em altas diluições e óleos essenciais homeopatizados / Feasibility of forage species seeds with high dilutions treatments and homeopathized essential oils

A alta viabilidade de sementes de espécies forrageiras é fundamental para um bom desempenho e estabelecimento das culturas a campo. O objetivo desse estudo foi avaliar o efeito do preparado homeopático Silicea terra 12 CH e a homeopatização de óleos essenciais de aroeira e alecrim-do-campo na 6CH na superação de dormência e germinação de sementes de Avena strigosa (Aveia preta), Lolium multiflorum (Azevém anual) e Paspalum notatum (Pensacola). Os experimentos foram conduzidos no Laboratório de Homeopatia e Saúde Vegetal da EPAGRI e no Laboratório de Sementes da Universidade do Estado de Santa Catarina, Lages/SC. O delineamento experimental foi o inteiramente casualizado, com 50 sementes e 4 repetições para cada espécie. As sementes foram dispostas em papel germitest e condicionadas em câmaras de germinação. As espécies foram avaliadas quanto a viabilidade (1ª contagem) e com teste padrão de germinação indicado nas Regras de Análises de Sementes. Os dados foram analisados com auxílio do ambiente R, considerando o nível de 5% de significância. Os resultados encontrados indicaram que o preparado homeopático Silicea terra 12CH atuou na velocidade de germinação, promovendo maiores taxas germinativas para todas as sementes testadas durante a primeira contagem. O índice de germinação da espécie Pensacola foi superior com o uso de Silicea terra 12CH ao final do experimento, diferindo significativamente do controle. O uso de óleo essencial homeopatizado de alecrim-do- -campo e aroeira atuaram sobre a viabilidade de azevém-anual na primeira contagem. Preparados homeopáticos e óleo essencial homeopatizado podem auxiliar na quebra de dormência de sementes de espécies forrageiras.

The high viability of forage species seeds is fundamental for a good performance and establishment of crops in the field. The objective of this study was to evaluate the effect of the homeopathic preparation Silicea terra 12 CH and the homeopathization of essential oils of mastic and rosemary-of-the-field in 6CH in overcoming dormancy and germination of Avena strigosa (black oat) seeds, Lolium multiflorum (anual Ryegrass) and Paspalum notatum (Pensacola). The experiments were conducted at the EPAGRI Homeopathy and Plant Health Laboratory and at the Seed Laboratory at the State University of Santa Catarina, Lages / SC. The experimental design was completely randomized, with 50 seeds and 4 replicates for each species. The seeds were placed on germitest paper and conditioned in germination chambers. The species were evaluated for viability (1st count) and with a standard germination test indicated in the Seed Analysis Rules. The data were analyzed with the aid of the R environment, considering the level of 5% of significance. The findings indicated that the homeopathic preparation Silicea terra 12CH acted at the germination speed promoting higher germination rates for all seeds tested during the first count. The germination index of the Pensacola species was higher with the use of Silicea terra 12CH at the end of the experiment, differing significantly from the control. The use of homeopathized essential oil of rosemary- -of-the-field and mastic influenced the viability of ryegrass in the first count. Homeopathic preparations and homeopathized essential oils can assist in breaking dormancy of seeds of forage species.

Development and evaluation of topical formulations that contain hydroethanolic extract from Schinus terebinthifolia against HSV-1 infection

Abstract The therapeutic drugs to treat Herpes simplex virus (HSV) infections have toxic side effects and there has been an emergence of drug-resistant strains. Therefore, the search for new treatments for HSV infections is mounting. In the present study, semi-solid formulations containing a crude hydroethanolic extract (CHE) from Schinus terebinthifolia were developed. Skin irritation, cutaneous permeation, and in vivo therapeutic efficacy of the formulations were investigated. Treatment with the ointment formulations did not result in any signs of skin irritation while the emulsions increased the thickness of the epidermis in Swiss mice. The cutaneous permeation test indicated that the CHE incorporated in the formulations permeated through the skin layers and was present in the epidermis and dermis even 3 h after topical application. In vivo antiviral activity in BALB/c mice treated with the CHE ointments was better than those treated with the CHE emulsions and did not significantly differ from an acyclovir-treated group. Taken together, this suggests that the incorporation of CHE in the ointment may be a potential candidate for the alternative topical treatment of herpetic lesions.

Preliminary prospection of phytotherapic compounds from the essential oils from barks and leaves of Umburana (Commiphora Leptophloeos)

Abstract The potential of the biome caatinga (exclusive from northeastern Brazil) has been evaluated in recent research for application in the pharmaceutical industry. Among the species of medicinal plants from caatinga, one can highlight the Commiphora leptophloeos (umburana), which has been used as infusions and syrups by the regional population for inflammatory and infectious diseases. Essential oils from umburana leaves and barks were obtained in a Clevenger apparatus and analyzed by gas chromatography/mass spectrometry, and total phenolic and flavonoids were determined by spectrophotometric analysis. It was observed that a large part of the major compounds present in the essential oil is described as having antitumor activity, enabling research in investigational oncology with umburana (C. leptophloeos). In addition, some little explored components have been identified, such as cadinene, alpha-selinene, and elemenone. Despite being easily found in several plants, there are no clinical trials involving their biological activity in a well-defined isolated form, which could make exploring new studies possible. Furthermore, the presence of phenolic compounds and flavonoids allows future studies about the potential antimicrobial and antioxidant activity.

Effect of Spondias mombin L. extract on the wettability, roughness, color and morphology of bovine enamel

Although Spondias mombin L. extract has an excellent antimicrobial effect against oral microorganisms, it should be clarified how it affects enamel surface properties. Aim: To evaluate the color change, wettability/contact angle, surface roughness and morphology of bovine enamel submitted to the Spondias mombin L. extract. Methods: Thirty bovine teeth were distributed into the following groups: 0.12% chlorhexidine digluconate, 1:32 Spondias mombin L. extract and distilled water. Color change (CC) was evaluated after immerging specimens into the solutions for 14 days. Surface roughness (Ra) was measured using a roughness meter; wettability/contact angles (CA) were determined by the sessile drop method, and scanning electron microscopy images were obtained to characterize the morphology (SMA). The pH of the solutions was evaluated using a pHmeter. The Ra, CA, and CC data were parametric (Kolmogorov-Smirnov; p>0.05). Two-way ANOVA (for Ra and CA) and one-way ANOVA (for CC) with Tukey's posthoc tests at a significance level of 5% were used. SMA was analyzed descriptively. Results: The Spondias mombin L. extract revealed an acidic pH, and when in contact with the bovine teeth, it increased the wettability, but it did not cause statistically significant differences in the Ra. Spondias mombin L. extract caused the highest color change. The SEM images showed differences in the specimens' surface submitted to the extract compared to the other groups. Conclusion: Spondias mombin L. extract provided negative effects on bovine enamel's surface, including a high color change and a more wettable substrate

Spondias mombin (Anarcadiaceae): molecular characterization and conservation / Spondias mombin (Anarcadiaceae): caracterización molecular y conservación

Abstract Introduction: The fruit of the yellow mombin (Spondias mombin L.) is notable due to its sensory and functional qualities. However, there is little knowledge regarding the genetic diversity of this species, and this would aid the implantation of the cultivation of the fruit as a crop, since current production is based on extractivism. Objective: Evaluate the diversity and genetic structure of natural populations of S. mombin in the state of Mato Grosso, Brazil, through microsatellite molecular markers in order to assist in the implementation of conservation strategies and the collection of genetic resources. Methods: A total of 139 S. mombin individuals were sampled in ten natural populations. PCR amplifications were performed with seven fluorescence-marked microsatellite primers. Genetic diversity was evaluated by the number of alleles, expected (He) and observed heterozygosity (Ho), polymorphic information content (PIC), fixation index (ƒ), rare and exclusive alleles. The genetic structure was evaluated using AMOVA, UPGMA dendrogram and Bayesian statistical analysis. Results: 46 alleles were amplified, which had an average of 6.6 alleles per locus. He was higher than Ho and f was positive, indicating the presence of inbreeding. The PIC ranged from 0.048 to 0.700, and only two loci were poorly informative. We found 27 rare alleles and 16 unique alleles. The largest component of variation was intrapopulational (90.64 %). The estimated gene flow was 1.99, which indicates that there is no genetic isolation between populations, and justifies the FST value (0.0963). The ten populations were grouped into two groups, and two populations constituted an isolated group. The Mantel test demonstrated that the genetic structure is not related to the geographic distance between populations. Conclusion: There is genetic diversity in the populations of S. mombin, which must be conserved in situ or ex situ, due to the diversity they present and because they are promising sources for collection of germplasm.

Resumen Introducción: El fruto amarillo del jobo o yuplón (Spondias mombin L.) destaca por sus cualidades sensoriales y funcionales. Sin embargo, existe poco conocimiento sobre la diversidad genética de esta especie, lo que ayudaría a la implantación del cultivo del fruto como cultivo, ya que la producción actual se basa en el extractivismo. Objetivo: Evaluar la diversidad y estructura genética de poblaciones naturales de S. mombin en el estado de Mato Grosso, Brasil, a través de marcadores moleculares microsatélites para ayudar en la implementación de estrategias de conservación y recolección de recursos genéticos. Métodos: Se muestrearon un total de 139 individuos de S. mombin en diez poblaciones naturales. Las amplificaciones por PCR se realizaron con siete cebadores de microsatélites marcados con fluorescencia. La diversidad genética se evaluó por el número de alelos, heterocigosidad esperada (He) y observada (Ho), contenido de información polimórfica (PIC), índice de fijación (ƒ), alelos raros y exclusivos. La estructura genética se evaluó mediante AMOVA, dendrograma UPGMA y análisis estadístico bayesiano. Resultados: Se amplificaron 46 alelos, los cuales tenían un promedio de 6.6 alelos por locus. Fue más alto que Ho y f positivo, lo que indica la presencia de endogamia. El PIC osciló entre 0.048 y 0.700, y solo dos loci fueron poco informativos. Encontramos 27 alelos raros y 16 alelos únicos. El mayor componente de variación fue intrapoblacional (90.64 %). El flujo de genes estimado fue de 1.99, lo que indica que no hay aislamiento genético entre poblaciones y justifica el valor de FST (0.0963). Las diez poblaciones se agruparon en dos grupos y dos poblaciones constituyeron un grupo aislado. La prueba de Mantel demostró que la estructura genética no está relacionada con la distancia geográfica entre poblaciones. Conclusión: Existe diversidad genética en las poblaciones de S. mombin, la cual debe ser conservada in situ o ex situ, por la diversidad que presentan y porque son fuentes promisorias para la recolección de germoplasma.

Abstract Introduction: Spondias tuberosa is a tree endemic to the semiarid region of Brazil with fruticulture potential. Objective: To estimate the diversity and genetic structure of S. tuberosa accessions from four areas of the semiarid region of Brazil, in order to facilitate conservation genetic resources studies in this species. Methods: DNA was extracted, using the CTAB 2x method, from leaf samples of 24 accessions of S. tuberosa available in the germplasm bank at Embrapa Semiárido, Brazil. Ten microsatellite loci were used in this study. Results: The UPGMA dendrogram, generated with a Jaccard coefficient similarity matrix, contains four groups at a 0.44 cutoff point. The similarity coefficient ranged from 0.30 to 0.84, indicating great divergence among the accessions. A Bayesian analysis conducted with the software Structure suggests there are two subpopulations, one formed by accessions from the Januária region and another by accessions from the Juazeiro, Uauá and Petrolina regions. The ΦST value of 0.12 for the analysis of molecular variance indicates moderate genetic differentiation among the four populations, suggesting that the genetic variability is moderately structured in function of region. Conclusions: Together, the analyses indicate that the genetic diversity of S. tuberosa is not uniformly distributed in the studied regions. Thus, germplasm from a greater number of populations should be collected to increase the germplasm bank genetic diversity of the species.

Resumen Introducción: Spondias tuberosa es un árbol endémico de la región semiárida de Brasil con potencial frutícola. Objetivo: Estimar la diversidad y caracterizar la estructura genética de accesiones de S. tuberosa en cuatro áreas del semiárido brasileño, para así facilitar estudios de conservación de recursos genéticos de esta especie. Metodología: El ADN fue extraído utilizando el método CTAB 2x a partir de muestras de hojas de 24 accesiones de S. tuberosa disponibles en el banco de germoplasma de Embrapa Semiárido, Brasil. Diez loci de microsatélites fueron usados en este estudio. Resultados: El dendrograma UPGMA generado con una matriz de similitud de coeficientes de Jaccard, formó cuatro grupos con punto de corte en 0.44. El coeficiente de similitud osciló entre 0.30 y 0.84, indicando una gran divergencia entre las accesiones. El análisis Bayesiano realizado en el software Structure sugiere la existencia de dos subpoblaciones, una formada por las accesiones de la región de Januária y otra derivada de las regiones de Juazeiro, Uauá y Petrolina. El valor de ΦST de 0.12 derivado del análisis molecular de la varianza indica moderada variación genética entre las cuatro poblaciones, sugiriendo que la variabilidad genética se estructura moderadamente en función de la región. Conclusiones: Los análisis en conjunto indican que la diversidad genética de S. tuberosa no se encuentra distribuida uniformemente en las regiones estudiadas. Por lo tanto, se debe recolectar germoplasma de un mayor número de poblaciones para aumentar la diversidad genética del banco actual de la especie.

Potencial antimicrobiano e antibiofilme do extrato hidroetanólico da folha de Spondias mombin L e de suas frações frente a microrganismos superinfectantes do meio ambiente bucal / Antimicrobial and antibiofilm potential of the hydroethanolic extract of Spondias mombin L leaf and its fractions against superinfecting microorganisms in the oral environment

O controle químico do biofilme bucal atua como método auxiliar do controle mecânico para fins de manutenção e/ou restabelecimento da saúde bucal, agindo também nos demais microrganismos que não são residentes locais da microbiota bucal. Nesse contexto, a literatura já relata que muitos microrganismos superinfectantes podem estar presentes no biofilme bucal e assim, contribuir para a ocorrência de infecções sistêmicas mais graves. Assim sendo, os fitoterápicos têm demonstrado uma ampla variedade de atividades biológicas, em especial a atividade antimicrobiana. Diante disso, o presente estudo buscou avaliar a ação antimicrobiana e antibiofilme do extrato hidroetanólico da folha de Spondias mombin L. (cajá) e de suas frações de flavonóides, taninos e ácidos fenólicos, frente aos microrganismos superinfectantes (Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli e Enterococcus faecalis) do ambiente bucal. Para isso, foram investigadas a Concentração Inibitória Mínima (CIM) pela Técnica de Disco-Difusão e pela Técnica da Microdiluição em Caldo, a Concentração Inibitória Mínima de Aderência (CIMA), a Cinética Bactericida e a Atividade Antibiofilme do extrato hidroetanólico da folha Spondias mombin L. e de suas frações sobre a formação de biofilme e em biofilmes pré-formados, utilizando como controle o digluconato de clorexidina a 0,12%, em triplicata. Além da interpretação descritiva, foram aplicados no presente estudo as análises estatísticas do Teste de Tukey e Two-Way ANOVA. Os resultados demonstraram que: para a CIM pela Técnica de Disco-Difusão, o extrato hidroetanólico da folha Spondias mombin L. foi estatisticamente superior ao digluconato de clorexidina 0,12% (p<0,05) para as concentrações de 500µg/mL e250µg/mLe foi estatisticamente superior também às frações estudadas (p<0,05); para a CIM pela Técnica da Microdiluição em Caldo, foi observado que o extrato hidroetanólico da folha Spondias mombin L. foi superior às frações estudadas e semelhante ao grupo controle; para a CIMA, tanto o extrato hidroetanólico da folha de Spondias mombin L., quanto as frações estudadas e o grupo controle exibiram atividade antiaderente; para a Cinética Bactericida, foi verificado que o extrato hidroetanólico, as frações estudadas e o grupo controle possuem atividade bactericida iniciando nas primeiras duas horas de contato com o microrganismo e para a Atividade Antibiofilme, foi observado que, sobre a formação de biofilme e em biofilmes pré-formados, em diferentes concentrações, o extrato hidroetanólico da folha Spondias mombin L. foi estatisticamente superior ao grupo controle (p<0,05), sendo também estatisticamente superior às frações estudadas (p<0,05). Dessa forma, pode-se concluir que o extrato hidroetanólico da folha Spondias mombin L., em diferentes concentrações, se apresentou estatisticamente superior que o digluconato de clorexidina 0,12%, exibindo assim, ação antimicrobiana e atividade antibiofilme. As frações do extrato, porém, exibiram ação antimicrobiana e atividade antibiofilme inferiores ao extrato hidroetanólico e ao digluconato de clorexidina 0,12% (AU).

The chemical control of oral biofilm acts as an auxiliary method of mechanical control for the maintenance and/or restoration of oral health, also acting on other microorganisms that are not local residents of the oral microbiota. In this context, the literature already reports that many superinfecting microorganisms can be present in the oral biofilm and thus contribute to the occurrence of more serious systemic infections. Therefore, herbal medicines have demonstrated a wide variety of biological activities, especially antimicrobial activity. Therefore, this study aimed to evaluate the antimicrobial and antibiofilm action of the hydroethanolic extract of the leaf of Spondias mombin L. (cajá) and its fractions of flavonoids, tannins and phenolic acids, against superinfecting microorganisms (Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Enterococcus faecalis) from the oral environment. For this purpose, the Minimum Inhibitory Concentration (MIC) by the Disc-Diffusion Technique and the Broth Microdilution Technique, the Minimum Inhibitory Concentration of Adhesion (MICA), the Bactericidal Kinetics and the Antibiofilm Activity of the hydroethanolic extract of the Spondias mombin L. leaf were investigated and its fractions on biofilm formation and in preformed biofilms, using 0.12% chlorhexidine gluconate as a control, in triplicate. In addition to descriptive interpretation, statistical analyzes of the Tukey Test and Two-Way ANOVA were applied in this study. The results showed that: for MIC by the Disc-Diffusion Technique, the hydroethanolic extract of the Spondias mombin L. leaf was statistically superior to 0.12% chlorhexidine gluconate (p<0.05) for the concentrations of 500µg/mL and 250µg/mL and it was also statistically superior to the studied fractions (p<0.05); for the MIC by the Broth Microdilution Technique, it was observed that the hydroethanolic extract of the Spondias mombin L. leaf was superior to the studied fractions and similar to the control group; for MICA, both the hydroethanolic extract of the leaf of Spondias mombin L., the studied fractions and the control group exhibited antiadherent activity; for Bactericidal Kinetics, it was verified that the hydroethanolic extract, the studied fractions and the control group have bactericidal activity starting in the first two hours of contact with the microorganism and for the Antibiofilm Activity, it was observed that, on the formation of biofilm and in biofilms preformed, at different concentrations, the hydroethanolic extract of the Spondias mombin L. leaf was statistically superior to the control group (p<0.05), being also statistically superior to the studied fractions (p<0.05). Thus, it can be concluded that the hydroethanolic extract of the Spondias mombin L. leaf, at different concentrations, was statistically superior to 0.12% chlorhexidine gluconate, thus exhibiting antimicrobial action and antibiofilm activity. The extract fractions, however, exhibited lower antimicrobial and antibiofilm activity than hydroethanolic extract and 0.12% chlorhexidine gluconate (AU).

Veterinary phytotherapy in Algeria: Pistacia lentiscus as an antimicrobial model / Fitoterapia veterinária na Argélia: emprego da Pistacia lentiscus como um modelo antimicrobiano

Currently, the use of alternative medicine is necessary, even in animals. Our study focused on the valorisation of the use of herbal products in Algerian veterinary medicine. This study is based on a 6-month exploratory survey of 257 private practicing veterinarians, followed by a study of the bacteriological activity of the essential oil of the Pistacia lentiscus plant. The survey results generally indicate that private veterinarians support phytotherapy as an alternative to conventional drugs in several areas and species. Also, the results of research conducted on the antibacterial activity of Pistacia lentiscusessential oil show that it inactivates 50% of the bacterial strains. This confirms the well-defined role of this medicinal plant used as an alternative in veterinary medicine.(AU)

Purification and component identification of total proanthocyanidins in Choerospondias axillaris pericarp / 中国中药杂志

The present study determined the quantitative markers of total proanthocyanidins in the purification of the industrial waste Choerospondias axillaris pericarp based on the comparison results of high-performance liquid chromatography(HPLC) and mass spectrometry(MS) and optimized the purification process with two stable procyanidins as markers. The adsorption and desorption of five different macroporous adsorption resins, the static adsorption kinetics curve of NKA-Ⅱ resin, the maximum sample load, and the gradient elution were investigated. The UPLC-Q-TOF-MS/MS was employed for qualitative analysis of the newly-prepared total proanthocyanidins of C. axillaris pericarp. As revealed by the results, NKA-Ⅱ resin displayed strong adsorption and desorption toward total proanthocyanidins. The sample solution(50 mg·mL~(-1)) was prepared from 70% ethanol crude extract of C. axillaris pericarp dissolved in water and 7-fold BV of the sample solution was loaded, followed by static adsorption for 12 h. After 8-fold BV of distilled water and 6-fold BV of 10% ethanol were employed to remove impurities, the solution was eluted with 8-fold BV of 50% ethanol, concentrated, and dried under reduced pressure, and purified total proanthocyanidin powder was therefore obtained. Measured by vanillin-hydrochloric acid method, the purity and transfer rate of total proanthocyanidins were 47.67% and 59.92%, respectively, indicating the feasibi-lity of the optimized process. UPLC-Q-TOF-MS/MS qualitative analysis identified 16 procyanidins in C. axillaris total proanthocyanidins. The optimized purification process is simple in operation and accurate in component identification, and it can be applied to the process investigation of a class of components that are difficult to be separated and purified. It can also provide technical support and research ideas for the comprehensive utilization of industrial waste.

Atividade antifúngica e potencial antibiofiome do extrato hidroetanólico de Spondias mombin L. e de suas frações frente a leveduras do gênero Candida / Antifungal activity and antibiofiome potential of the hydroethanolic extract of Spondias mombin L. and its fractions against yeasts of the genus Candida

A Candidose é uma patologia que pode ter manifestações locais e também sistêmicas e acontece pela proliferação de fungos do gênero Candida. O tratamento desta patologia é realizado com antifúngicos mas, devido a resistência dos fungos causadores desta enfermidade se faz necessário conhecer outros antifúngicos. A ação antimicrobiana do extrato hidroetanólico de Spondias mombin L. já é conhecida e é fundamental que seja pesquisado a atividade antibiofilme das substâncias, uma vez que estes fungos causam adoecimento quando se acumulam e proliferam. Sabendo disso é que o presente estudo teve por objetivo principal investigar a ação antifúngica e antibiofilme do extrato hidroetanólico (EH) de Spondias mombin L. e das frações de taninos, flavonoides e ácidos fenólicos, frente a fungos do gênero Candida, de importância clínica. Para isto, determinou-se a concentração inibitória mínima por meio do uso de discos e pela técnica da microdiluição em caldo, concentração inibitória mínima de aderência, determinação da curva de morte dos fungos e atividade antibiofilme das frações de ácidos fenólicos, flavonoides e tanino, frente aos fungos Candida albicans, Candida tropicalis, Candida Krusei e Candida Glabrata, utilizando como controle positivo a Nistatina (100.000 UI), em triplicata. Foi visto que, a atividade antifúngica e antibiofilme do EH e de suas frações analisadas existe, porém, quando comparamos as frações com o EH este último apresentou melhor atividade em suas maiores concentrações (500 µg/mL e 250 µg/mL) e quando traçamos o comparativo entre a ação antifúngica e antibiofilme das substâncias testadas e do grupo controle, tivemos melhores resultados do grupo controle frente aos fungos testados. Desta forma foi possível concluir que o extrato hidroetanólico apresentam resultados superiores de atividade antifúngica frente a todos os microrganismos testados, exceto C. krusei e antibiofilme frente a, pelo menos, uma das espécies de Candida e que este extrato teve resultados muito semelhantes e, por vezes, superior ao grupo controle (AU).

Candidosis is a pathology that can have local as well as systemic manifestations and happens due to the proliferation of fungi of the Candida genus. The treatment of this pathology is carried out with antifungal agents, but due to the resistance of the fungi that cause this disease, it is necessary to know other antifungal agents. The antimicrobial action of the hydroethanolic extract of Spondias mombin L. is already known and it is essential that the antibiofilm activity of the substances be researched, since these fungi cause illness when they accumulate and proliferate. Knowing that, this study aimed to investigate the antifungal and antibiofilm action of the hydroethanolic extract (EH) of Spondias mombin L. and its fractions, against fungi of the genus Candida, of clinical importance. For this, the minimum inhibitory concentration was determined through the use of disks and the technique of microdilution in broth, minimum inhibitory concentration of adhesion, determination of the fungal death curve and antibiofilm activity of the fractions of phenolic acids, flavonoids and tannin, against the fungi Candida albicans, Candida tropicalis, Candida Krusei and Candida Glabrata, using nystatin (100,000 IU) as a positive control, in triplicate. It was seen that the antifungal and antibiofilm activity of EH and its analyzed fractions exists, however, when we compare the fractions with EH, the latter showed better activity at its highest concentrations (500 µg/mL e 250 µg/mL) and when we draw the comparison between the antifungal and antibiofilm action of the tested substances and the control group, we had better results than the control group against the tested fungi. Thus, it was possible to conclude that the hydroethanolic extract presented superior results of antifungal activity against all tested microorganisms, except C. krusei and antibiofilm against at least one of the Candida species and that this extract had very similar results and, for times higher than the control group (AU).

Spondias mombin L. decoction utilization as antiseptic in cats submitted to castration / Uso de decocto de Spondias mombin L. como antisséptico em felinos submetidos à castração

This survey evaluated mombin leaves (Spondias mombin L.) decoction efficiency as an antiseptic during post-surgery period on cats submitted to orchiectomy and ovariosalpingohisterectomy. For this purpose, 45 castrated mongrels cats were divided into three groups, the first group as a positive control using 0.5% chlorhexidine-alcohol solution, the second a negative control group using sterile distilled water and, finally, the test group using mombin leaves decocted with a concentration of 100 mg/mL. All animals, independent of age and sex, had visibly healed in most cases in a similar time. Animals treated with mombin leaves decoction presented a significant reduction of bacterial growth. In addition, the animals treated in the test group had better surgical wound healing. All isolated bacterial strains presented inhibition halo for chlorhexidine and for Spondias mombin L. Thus, the decoction of Spondias mombin L. leaves proved antiseptic efficacy in the surgical wounds of cats submitted to orchiectomy and ovariosalpingohisterectomy.(AU)

Foi avaliada a eficiência do decocto das folhas de cajá (Spondias mombin L.) como antisséptico no pós-cirúrgico de gatos submetidos à orquiectomia e ovariosalpingohisterectomia. Para tal, foram submetidos à castração 45 gatos sem raça definida, divididos em três grupos. O primeiro grupo como controle positivo com Solução Alcoólica de Clorexidine a 0,5%; segundo grupo controle negativo com água destilada estéril; e o grupo teste com o decocto de cajá à concentração de 100 mg/mL. Todos os animais, independentemente da idade e sexo, tiveram cicatrização visível em tempo similar. Animais tratados com o decocto apresentaram uma redução significativa do crescimento bacteriano. Além disso, observou-se uma melhor cicatrização das feridas cirúrgicas dos animais tratados no grupo teste. Todas as estirpes bacterianas isoladas apresentaram halo de inibição para clorexidine e para Spondias mombin L. Portanto, o decocto das folhas da Spondias mombin L. apresentou eficácia antisséptica nas feridas cirúrgicas de gatos submetidos à orquiectomia e ovariosalpingohisterectomia.(AU)

Wound healing effect of Pistacia lentiscus L. seed oil: confirmation of its uses in Mediterranean traditional medicine / Efecto curativo de heridas del aceite de semilla de Pistacia lentiscus L: confirmación de sus usos en medicina tradicional mediterránea

In order to evaluate the potential of this formulation (P. lentiscus L. oil-based ointment) to heal wounds, experimental wounds were done on guinea pigs and efficiency was comparatively assessed against a reference ointment, Cicaderma®. Wound contraction was performed on days 5, 10 and 15. Tissue sections were also evaluated histopathological on days 7, 14 and 21. Results showed that for all days (5, 10 and 15), the highest wound contraction values were attained for the P. lentiscus oil-based ointment treated group with wound contraction values of 19.38, 55.8 and 77.11%, respectively, as compared to the reference drug Cicaderma® where contractions were 7.97%, 49.53% and 71.44%, respectively. Vehicle and negative control groups however showed no statistically significant wound healing activity on the excision wound model. These experimental studies revealed that the P. lentiscus oil-based ointment displays remarkable wound healing activity, in accordance with its use in traditional medicine.

Con el fin de evaluar el potencial de esta formulación (ungüento a base de aceite de P. lentiscus L.) para curar heridas, se realizaron heridas experimentales en cobayos y se evaluó comparativamente su eficacia respecto de un ungüento de referencia, Cicaderma®. La contracción de la herida se realizó los días 5, 10 y 15. Las secciones de tejido también se evaluaron histopatológicamente los días 7, 14 y 21. Los resultados mostraron que para todos los días (5, 10 y 15), se obtuvieron los valores más altos de contracción de la herida para el grupo tratado con ungüento a base de aceite de P. lentiscus con valores de contracción de la herida de 19.38, 55.8 y 77.11%, respectivamente, en comparación con el medicamento de referencia Cicaderma® en donde las contracciones fueron 7.97%, 49.53% y 71.44%, respectivamente. Sin embargo, los grupos de control de vehículo y negativo no mostraron actividad de curación de heridas estadísticamente significativa en el modelo de herida por escisión. Estos estudios experimentales revelaron que la pomada a base de aceite de P. lentiscus muestra una notable actividad de curación de heridas, de acuerdo con su uso en la medicina tradicional.
