ABSTRACT

Abstract Origanum vulgare has been of great interest in academia and pharma industry due to its antioxidant, antifungal and antitumor properties. The present study aimed to find the anti-MRSA potential and in vivo toxicity assessments of O. vulgare. O. vulgare extract was used to monitor anti-MRSA activity in mice. Following MRSA established infection in mice (Mus musculus), treatment with O. vulgare was continued for 7 days. Autopsies were performed and re-isolation, gross lesion scoring and bacterial load in various organs were measured. Additionally, blood sample was analysed for hematological assays. Toxicity assessment of O. vulgare potential as medicine was done at 200 mg/kg and 400 mg/kg by evaluating liver and kidney functions. Bacterial load and gross lesion in lungs and heart were significantly low compared to positive control following O. vulgare treatment. Likewise, O. vulgare treated groups had hematological, neutrophil and TLC values similar to control groups. Increased AST, ALP and total bilirubin alongwith marked hepatocellular degeneration and distortion around the central vein, inflammatory cell infiltration, and cytoplasmic vacuolization of hepatic cells was observed at higher dose. It is concluded that crude extract of O. vulgare may contain beneficial secondary metabolites and in future may be explored for curing infectious diseases.


Resumo Origanum vulgare tem despertado grande interesse na academia e na indústria farmacêutica devido às suas propriedades antioxidantes, antifúngicas e antitumorais. O presente estudo teve como objetivo encontrar o potencial anti-MRSA e avaliações de toxicidade in vivo de O. vulgare. O extrato de O. vulgare foi usado para monitorar a atividade anti-MRSA em camundongos. Após infecção estabelecida por MRSA em camundongos (Mus musculus), o tratamento com O. vulgare foi continuado por 7 dias. As autópsias foram realizadas e o reisolamento, pontuação das lesões grosseiras e carga bacteriana em vários órgãos foram medidos. Além disso, a amostra de sangue foi analisada para ensaios hematológicos. A avaliação da toxicidade do potencial de O. vulgare como medicamento foi feita com 200 mg / kg e 400 mg / kg, avaliando as funções hepática e renal. A carga bacteriana e as lesões graves nos pulmões e no coração foram significativamente baixas em comparação com o controle positivo após o tratamento com O. vulgare. Da mesma forma, os grupos tratados com O. vulgare apresentaram valores hematológicos, de neutrófilos e de TLC semelhantes aos grupos de controle. Aumento de AST, ALP e bilirrubina total juntamente com degeneração hepatocelular marcada e distorção ao redor da veia central, infiltração de células inflamatórias e vacuolização citoplasmática de células hepáticas foram observados em doses mais altas. Conclui-se que o extrato bruto de O. vulgare pode conter metabólitos secundários benéficos e, no futuro, pode ser explorado para a cura de doenças infecciosas.

ABSTRACT

Abstract The aim of this study was to evaluate the antimicrobial effect of the essential oils of cinnamon, cardamom, clove, oregano, and thyme and their synergism on vegetative cells and endospores of Clostridium perfringens type A inoculated in meat sausage (mortadella), as well as the influence of blends on the color, and lipid oxidation through the determination of thiobarbituric acid reactive substances (TBARS index). The anticlostridial action of the oil blends was established. The two added oil blends (Treat. 1: oregano, clove, and thyme; Treat. 2: oregano, clove, and cinnamon) in combination with reduced nitrite content (75 ppm) promoted a lower growth of C. perfringens in mortadella stored at 15 °C for 21 days in comparison to treatments containing only 75 ppm of nitrite. The essential oil blends showed antioxidant action and did not alter food color, thus possessing potential application as a preservative for the meat products industry.

Determinar as concentrações fungicidas mínimas, o efeito dos óleos e dos compostos químicos em doses subinibitórias sobre a formação de tubo germinativo e a produção de franjas, nos isolados de C. albicans, antes e após contato com os diferentes óleos essenciais e os compostos químicos. Nesse estudo, todos os cinco óleos essenciais apresentaram atividade antimicrobiana sobre os isolados de C. albicans: O. vulgare apresentou CFM 90 de 1,5µg/mL, seguido pelos óleos essenciais de O. marajoana 2,6 µg/mL, S. sclarea 21,93µg/mL, R. officinalis 80,85µg/mL e O. basilicum 92,25 µg/mL. Nas doses sub inibitórias os óleos essenciais de O. vulgare, R. officinalis e S. sclarea inibiram em mais de 80% dos isolados de C. albicans a formação de tubo germinativo e alteraram a produção de franjas em mais de 70% dos isolados de C. albicans. O óleo essencial de O. vulgare foi o que apresentou a menor concentração fungicida sobre os isolados de C. albicans. O composto químico carvacrol do óleo essencial de O. vulgare foi o que apresentou a menor concentração fungicida sobre os isolados de C. albicans e a menor CFM90 0,69 µg/mL. Com excessão do p-cinemo todos os compostos químicos do óleo essencial de O. vulgare inibiram a formação de tubo germinativo e inibiram a produção de franja. Pelo exposto e nas condições desse estudo, conclui-se que o óleo essencial de O. vulgare e o composto químico carvacrol apresentaram a menor concentração fungicida sobre os isolados biológicos de C. albicans.

ABSTRACT

Putre ́s oregano (Origanum vulgare L.) is a variety of oregano that grown in the Arica-Parinacota Region. Its organoleptic attributes and unique production conditions have earned it a certification with Geographical Indication (GI). However, the demands of the markets require a scientific-technological support for identification and authentication of materials. In this context, was proposed to identify Putre's oregano by phylogenetic relationships based on the use of molecular markers SSR and "DNA Barcode". The results showed that when comparing materials from different sources of Putre ́s oregano versus information from certified germplasms and GenBank sequences, added to the analysis with nuclear genetic markers, Putre ́s oregano corresponds to the species Origanum vulgare L. subsp virens. This precise identification will support the correct differentiation and authentication of this genotype, serving in addition to supporting the GI.

ABSTRACT

O óleo de peixe é fonte de ômega 3, que atua no combate, prevenção e/ou tratamento de doenças crônicas. O queijo coalho é bastante consumido no Nordeste brasileiro, e na forma de creme adicionado de óleo de peixe torna-se uma nova alternativa para o consumidor. Assim, objetivou-se desenvolver e avaliar formulações de creme de queijo coalho (CQQ) com orégano, com ou sem óleo de peixe. Inicialmente, foi realizada uma pesquisa com 70 consumidores de queijo, seguida da elaboração de três formulações de CQQ (F1: sem óleo de peixe; F2: com 0,54g óleo de peixe; F3: com 1,08g de óleo de peixe). Obtidos os CQQs, as formulações (F1, F2 e F3) foram avaliadas no que se refere a: fungos, coliformes totais e termotolerantes, estafilococus coagulase positiva e Salmonella sp; aceitação e preferência sensorial; composição centesimal, fenólicos totais, atividade antioxidante, pH, acidez total titulável e valor calórico. O sabor foi o fator mais importante na escolha de um produto, sendo o ômega 3 (54,28%) e o orégano (57,14%) escolhidos pela maioria dos entrevistados. Todas as formulações estavam seguras microbiologicamente e apresentaram a mesma aceitabilidade e preferência sensorial. A aceitabilidade variou entre 7,43 a 8,13. As formulações de CQQ são de acordo com a legislação, desnatadas (1,77 a 2,66% de lipídios), têm muito alta umidade (≥55%) e baixa acidez (3,12 a 3,28g ácido lácteo/100g), e apresentaram expressiva atividade antioxidante e potencial para comercialização (índice de aceitação ≥70%). Os CQQs são viáveis para incorporação de óleo de peixe, sendo um produto fonte de ômega 3 e que pode apresentar propriedade funcional. (AU)


Fish oil is a source of omega 3 that acts in the fight, prevention and/or treatment of chronic diseases. Coalho cheese is largely consumed in the Northeastern Brazil, and in the form of cream added with fish oil it becomes a new alternative to consumers. Thus, the aim of this study was to develop and assess coalho cheese cream (CCC) formulations added with oregano, with or without fish oil. Firstly, a survey was conducted with 70 cheese consumers, followed by the preparation of three CCC formulations (F1: without fish oil; F2: with 0.54g of fish oil; F3: with 1.08g of fish oil). The CCC formulations (F1, F2 and F3) were analyzed for fungi, total and thermotolerant coliforms, coagulase-positive staphylococci, and Salmonella sp.; acceptability and sensory preference were also assessed, as well as the centesimal composition, total phenols, antioxidant activity, pH, total titratable acidity and calories. Taste was the most important factor in the choice of the product, being omega 3 (54.28%) and oregano (57.14%) chosen by the majority of the participants. All formulations were microbiologically safe and had the same acceptability and sensory preference. The acceptability index varied from 7.43 to 8.13. The CCC formulations are in conformity with legislation, are low fat (1.77 to 2.66% of lipids), have high moisture (>55%) and low acidity (3.12 to 3.28g of lactic acid/100g), and have an expressive antioxidant activity and marketing potential (acceptability was >70%). The CCCs are viable for incorporation of fish oil, being an omega-3 source product with functional property. (AU)

ABSTRACT

Origanum vulgare L. (OVEO) essential oil has been considered a candidate antimicrobial for use in food conservation systems. However, studies on the influence of concomitant variations of different food components or physicochemical parameters on the antibacterial properties of OVEO are scarce. This study assessed the influence of concomitant variations in amounts of proteins - PTN (4.0, 6.0 or 8.0 g/100 mL) and lipids - LIP (3.75, 5.0 or 6.25 g/100 mL) and pH values (5.0, 5.5 or 6.0) in cultivation medium on the inhibitory effects of OVEO against Escherichia coli (EC) and Salmonella Typhimurium (ST). Lowest minimum inhibitory concentration values of OVEO against EC and ST were observed in media with the highest LIP amounts regardless the PTN amount and pH value. In absorbance based microtiter plate assay (MPA), for both EC and ST, OVEO caused the lowest Grmax values in medium containing the highest LIP and PTN amounts and lowest pH value. Highest Grmax values for EC and ST were observed in medium containing the lowest LIP and PTN amount and highest pH value. Grmax values estimated from viable counts of EC and ST in tested media with OVEO confirmed bacterial growth behavior similar to that observed in MPA. Overall, the LIP amount in media was as the most influential factor to enhance the antibacterial effects of OVEO. These results indicate that the concomitant influence of LIP and PTN amounts and pH values on the antibacterial effects of OVEO should be considered for optimizing its antimicrobial efficacy in foods.

ABSTRACT

Aspergillus fumigatus, A. flavus e A. niger são os mais importantes agentes etiológicos da aspergilose, relevante micose aviária, com tratamento ineficaz e altas taxas de mortalidade. Em vista da importância da aspergilose, da necessidade de prospectar novos fármacos e do potencial terapêutico do óleo essencial de Origanum vulgare L. (OEO), o orégano, objetivou-se avaliar a sensibilidade in vitro de isolados clínicos de Aspergillus spp. em relação ao OEO. O óleo foi obtido por hidrodestilação em Clevenger, e a análise química realizada por cromatografia de massa (GC/MS). Observaram-se 15 diferentes compostos ativos, sendo 4-terpineol, hidrato de sabinene e timol os majoritários. Nos testes de microdiluição em caldo (Reference..., 2008), todos os isolados (n= 23) foram sensíveis ao OEO: A. fumigatus teve CIM entre 28,125mg/mL (0,1875%) e 450mg/mL (3,0%), A. flavus entre 112,5mg/mL (0,75%) e 450mg/mL, e A. niger 112,5mg/mL. CFM variou de 112,5mg/mL a 450mg/mL nos isolados de A. fumigatus, de 225mg/mL (1,5%) a 450mg/mL em A. flavus, e foi de 450mg/mL em A. niger. CIM e CFM foram idênticos em 6/14 isolados, o que demonstra que o óleo com a mesma concentração pode ter capacidade fungistática e fungicida. CIM 90 correspondeu à CIM máxima. Os resultados demonstram a atividade anti-Aspergillus do OEO, com CIM 90 de 450mg/mL (3%).(AU)


Aspergillus fumigatus, A. flavus and A. niger are the most important etiological agents of aspergillosis, a relevant avian mycosis, with innefective treatment and high mortality rates. Due the importance of aspergillosis, the necessity of prospection of new drugs and the therapeutic potential of the essential oil of Origanum vulgare L. (OEO), popularly known as oregano, aims to evaluate the in vitro sensitivity of Aspergillus spp. opposing to OEO. The oil was obtained by hydrodistillation in Clevenger, and the chemical analysis performed by mass chromatography (GC/MS). 15 different active compounds were observed, being 4-terpineol (18.4%), sabinene hydrate (15.6%) and thymol (13.6%), the majority components. In the in vitro susceptibility test, all strains showed sensitivity to OEO, MIC of Aspergillus fumigatus ranged from 28,125mg/mL (0,1875%) to 450mg/mL (3,0%), A. flavus 112,5mg/mL (0,75%) to 450mg/mL, and A. niger 112,5mg/mL. MFC ranged from 112,5mg/mL to 450mg/mL in the A. fumigatus isolates, 225mg/mL (1,5%) to 450mg/mL in A. flavus, and 450mg/mL for A. niger. The MIC and FMC values were identical in 6/14 of the isolated subjects, demonstrating that the oil with the same concentration can have fungistatic and fungicidal capacity. The results demonstrates anti-Aspergillus activities of OEO with CIM90 de 450mg/mL (3%).(AU)

ABSTRACT

Abstract INTRODUCTION: Plant products are sources for drug development against multidrug resistant bacteria. METHODS The antimicrobial activity of Origanum vulgare L. essential oil (OVeo) against carbapenem-resistant strains was assessed by disk-diffusion, microdilution (REMA-Resazurin Microtiter Assay), and time kill assays. RESULTS Carbapenemase production was confirmed for all strains. OVeo exhibited a minimum inhibitory concentration of 0.059% v/v for Klebsiella pneumoniae and Serratia marcescens, and of 0.015 % v/v for Acinetobacter baumannii. A decrease in cell count was observed after a 4 h treatment. CONCLUSIONS OVeo antimicrobial effect was rapid and consistent, making it a candidate for developing alternative therapeutic options against carbapenem-resistant strains.

ABSTRACT

RESUMEN: El Streptococcus mutans es una de las principales bacterias que participa en el desarrollo de la caries dental, una enfermedad de alta prevalencia en la población mundial, y por ende un problema de salud pública. Hoy se intentan buscar alternativas para su prevención, una de ellas es la fitoterapia o uso de plantas medicinales con fines terapéutico beneficiosos para la salud. Evaluar efecto antibacteriano del Origanum vulgare a diferentes concentraciones sobre el crecimiento in vitro de Streptococcus mutans. Se utilizaron cepas bacterianas de Streptococcus mutans previamente aisladas, se realizó una siembra bacteriana en 24 placas Petri con agar mitis salivarius. Se prepararon infusiones de orégano a 8 concentraciones diferentes (1 %, 5 % y 10 %, 20 %, 40 %, 60 %, 80 % y 100 %) y se aplicaron en perforaciones realizadas previamente en las placas de agar (4 perforaciones por placa para las infusiones de orégano y 2 para las placas de controles). Se llevó a incubadora por 48 horas y posteriormente se realizó la medición de los halos de inhibición. Los resultados fueron negativos para las infusiones de orégano al 1 %, 5 % y 10 %, debido a que no presentaron halos de inhibición bacteriana; mientras que para las infusiones al 20 %, 40 %, 60 %, 80 % y 100 % los resultados fueron positivos. El orégano posee efecto antibacteriano sobre el crecimiento de Streptococcus mutans en infusiones sobre el 20 % de concentración, siendo la solución madre preparada a partir de 20 gramos de hojas secas de orégano (Origanum vulgare) y 200 ml de agua destilada hervida. Este efecto es antibacteriano es directamente proporcional a la concentración de la infusión. El orégano podría ser utilizado como una alternativa de colutorio, pasta dental u otros coadyuvantes de higiene bucal para prevenir la aparición de caries.


ABSTRACT: Streptococcus mutans is one of the main bacteria in the development of dental caries, a disease with high prevalence in the world population, and therefore a public health problem. There is current research to find prevention alternatives one of these is the use of medicinal plants for therapeutic purposes beneficial to health. To evaluate the antibacterial effect of Origanum vulgare at different concentrations on in vitro growth of Streptococcus mutans, previously isolated bacterial strains of Streptococcus mutans were used. Bacterial seeding was carried out in 24 petri dishes with agar Mitis salivarius. Oregano infusions were prepared at 8 different concentrations (1 %, 5 % and 10 %, 20 %, 40 %, 60 %, 80 % and 100 %) and applied in predrilled holes in the agar plates (4 perforations per plate for the oregano infusions and 2 for control plates). They were maintained in an incubator for 48 hours and measurement of the inhibition zones was subsequently carried out. The results were negative for infusions of oregano at 1 %, 5 % and 10 %, as they did not present halos of bacterial inhibition; while results were positive for infusions at 20 %, 40 %, 60 %, 80 % and 100 %. Results show that oregano has an antibacterial effect on the growth of Streptococcus mutans in infusion concentrations above 20 %, with the basic solution prepared from 20 g of dried oregano leaves (Origanum vulgare) and 200 ml of boiled distilled water. This antibacterial effect is directly proportional to the concentration of the infusion. Oregano could be used as an alternative mouthwash, toothpaste or other oral hygiene adjuvants to prevent the incidence of caries.

ABSTRACT

RESUMEN: El objetivo del estudio fue determinar el efecto antibacteriano in vitro de la oleorresina de Copaifera reticulata (C. reticulata) "copaiba" y del aceite esencial de Oreganum majoricum (O. majoricum) "orégano" frente a Streptococcus mutans (S. mutans) y Enterococcus faecalis (E. faecalis). Se desarrollaron pruebas de sensibilidad activando primero las cepas bacterias a enfrentar. La oleorresina de copaiba fue diluida con dimetilsulfósido (DMSO), obteniéndose al final concentraciones a probar de 100 %, 50 %, 25 %, y 12,5 %. En relación al aceite esencial de orégano este se probó solamente al 100 %. Para la prueba de difusión en agar con discos, se tomaron inóculos 100 µL de cada cepa bacteriana a una turbidez de 0,5 de Mc Farlam, para ser sembrados por diseminación en placas de tripticasa soya agar, para luego colocar los discos de forma equidistante cargados con las diferentes concentraciones de los productos naturales, se utilizaron como control positivo a la clorhexidina al 0,12 % y al DMSO como control negativo. Se incubaron las placas por el método de la vela en extinción a 37 °C, por un periodo de 24 horas, pasado el tiempo se realizó la lectura de los halos de inhibición. Los resultados obtenidos por la copaiba, determinaron un efecto antibacteriano en sus cuatro concentraciones, siendo los mayores halos de inhibición a la concentración del 100 %, copaiba genero mayores halos promedios para S, mutans de 30,00 ± 0,00 mm y para E. faecalis de 8,3 ± 0,50 mm. Para el caso del orégano se producen halos a la concentración del 100 % con un promedio de 25,3 ± 0,96 mm para S. mutans y para E. faecalis de 9,5 ± 1,29 mm. Se concluye del estudio que tanto copaiba como el orégano presentan un efecto antibacteriano para ambas bacterias, siendo su mayor efecto antibacteriano para ambos productos naturales sobre S. mutans.


ABSTRACT: The objective of the study was to determine the in vitro antibacterial effect of the oleoresin of Copaifera reticulata (C. reticulata) "copaiba" and of the essential oil of Oreganum majoricum (O. majoricum) "oregano" against Streptococcus mutans (S. mutans) and Enterococcus faecalis (E. faecalis). Sensitivity tests were developed by first activating the bacteria strains to be confronted. The oleoresin of copaiba was diluted with dimethylsulphoside (DMSO), obtaining final concentrations to be tested of 100 %, 50 %, 25 %, and 12.5 %. In relation to the essential oil of oregano, it was only 100 % tested. For the disk agar diffusion test, 100 mL of each bacterial strain was taken at a turbidity of 0.5 of Mc Farlam, to be planted by dissecting trypticase soy agar plates, and then placing the disks equidistantly loaded with the different concentrations of natural products; 0.12 % chlorhexidine was used as a positive control and DMSO as negative control. The plates were incubated by the candle method in extinction at 37 °C, for a period of 24 hours, after which time the inhibition halos were read. The results obtained by the copaiba, determined an antibacterial effect in its four concentrations, being the biggest halos of inhibition at the concentration of 100 %, copaiba genus higher average halos for S. mutans of 30.00 ± 0.00 mm and for E. faecalis of 8.3 ± 0.50 mm. In the case of oregano, haloes are produced at a concentration of 100 % with an average of 25.3 ± 0.96 mm for S. mutans and for E. faecalis 9.5 ± 1.29 mm. It is concluded from the study that both copaiba and oregano present an antibacterial effect for both bacteria, being its greater antibacterial effect for both natural products on S. mutans.

ABSTRACT

Antioxidantes são substâncias utilizadas para preservar alimentos por meio do retardamento da deterioração, da rancidez e descolorações decorrentes da oxidação. Os antioxidantes disponíveis incluem os sintéticos e os naturais, no entanto, devido à possibilidade de efeitos carcinogênicos e mutagênicos, cada vez mais, existe uma busca pelo uso de antioxidantes naturais. A CMS (Carne Mecanicamente Separada) origina-se do processamento da carne, sendo formado pelo dorso, pescoço e da desossa da ave após processamento da carne para formação dos cortes. A legislação brasileira recomenda no máximo até 30% de CMS na produção de hambúrgueres, demonstrando a possibilidade de seu aproveitamento em um produto de maior valor comercial. Além disso, por ser uma carne extremamente processada está mais sujeita à oxidação, o que faz com que seja necessário o uso de antioxidantes visando, principalmente, aumentar o tempo de prateleira. Dessa forma, fazem-se necessárias pesquisas avaliando o uso de antioxidantes naturais, tais como os óleos essenciais. Em pesquisa recente desenvolvida por nosso grupo de pesquisa foi avaliado a produção de hambúrgueres elaborados com CMS de aves (frangos e galinhas) e adicionado de óleo essencial de hortelã ou orégano como antioxidante em diferentes níveis (0,04; 0,06 e 0,08%) e resultados prévios demonstraram uma boa aceitabilidade no teste de preferência para qualquer um dos níveis utilizados. No entanto, os resultados da avaliação da capacidade antioxidante e análise microbiológica devem ser avaliados para se definir o melhor nível de uso dos óleos essenciais de orégano ou hortelã como antioxidante natural em produtos elaborados com CMS de aves.(AU)


Antioxidants are used to preserve food by delaying deterioration, rancidity and discoloration caused by oxidation. Antioxidants can be either synthetic or natural; however, due to the possibility of carcinogenic and mutagenic effects, there has been an increasing search for the use of natural antioxidants. Mechanically separated meat (MSM) originates from the meat processing, being formed by the back, neck and the deboning process of poultry, and the subsequent processing of the meat to form the cuts. The Brazilian legislation recommends a maximum of 30% of MSM in the production of hamburgers, demonstrating the possibility of its use in a product with greater commercial value. Moreover, since this is an extremely processed meat, it is more prone to oxidation, requiring the use of antioxidants to increase shelf life. Thus, research is needed to evaluate the use of natural antioxidants such as essential oils. In recent research developed by this research group, the production of hamburgers made with MSM from poultry and the addition of mint or oregano essential oil as antioxidant at different levels (0.04, 0.06, and 0.08%), with prior results showing good acceptability in the preference test for all the levels used. However, the antioxidant capacity assessment and microbiological analysis must be evaluated in order to determine the optimal usage level of oregano or mint essential oils as natural antioxidants in products made with poultry MSM.(AU)


Los antioxidantes son sustancias utilizadas para preservar los alimentos por medio de retraso del deterioro, de la rancidez y de las decoloraciones resultantes de la oxidación. Los antioxidantes disponibles incluyen los sintéticos y los naturales, sin embargo, debido a la posibilidad de efectos carcinogénicos y mutagénicos, cada vez más existen búsquedas por el uso de antioxidantes naturales. La CMS (carne mecánicamente separada) se origina del procesamiento de la carne, siendo formado por el dorso, el cuello y el deshuesado del ave después del procesamiento de la carne para la formación de los cortes. La legislación brasileña recomienda al máximo hasta un 30% de CMS en la producción de hamburguesas, demostrando la posibilidad de su aprovechamiento en un producto de mayor valor comercial. Además, por ser una carne extremadamente procesada está más sujeta a la oxidación, lo que hace que es necesario el uso de antioxidantes, buscando principalmente aumentar el tiempo de estantería. De esa forma, se hacen necesarias investigaciones evaluando el uso de antioxidantes naturales, tales como los aceites esenciales. En investigación reciente desarrollada por nuestro grupo de investigadores se evaluó la producción de hamburguesas elaboradas con CMS de aves (pollos y gallinas), agregado de aceite esencial de menta u orégano como antioxidante en diferentes niveles (0,04, 0,06 y 0, 08%), resultados previos demostraron una buena aceptación en la prueba de preferencia para cualquiera de los niveles utilizados. Sin embargo, los resultados de la evaluación de capacidad antioxidante y el análisis microbiológico deben ser evaluados para definir el mejor nivel de uso de los aceites esenciales de orégano o menta como antioxidante natural en productos elaborados con CMS de aves.(AU)

ABSTRACT

ABSTRACT The objective of this study was to evaluate the antifungal activity of nanoemulsions encapsulating essential oil of oregano (Origanum vulgare), both in vitro and after application on Minas Padrão cheese. Nanodispersions were obtained by the phase inversion temperature method. Cladosporium sp., Fusarium sp., and Penicillium sp. genera were isolated from cheese samples and used to evaluate antifungal activity. Minimal inhibitory concentrations of non-encapsulated and encapsulated oregano essential oil were determined, and they were influenced by the encapsulation of the essential oil depending on the type of fungus. The antifungal activity of the nanoencapsulated oregano essential oil in cheese slices showed no evidence of an effect of the MICs, when applied in the matrix. On the other hand, an influence of contact time of the nanoemulsion with the cheese was observed, due to the increase in water activity. It was concluded that nanoencapsulated oregano essential oil presented an inhibitory effect against the three genera of fungi evaluated. If environmental parameters, such as storage temperature and water activity, were controlled, the inhibitory effect of nanoemulsions of oregano oil could possibly be greatly improved, and they could be presented as a potential alternative for the preservation of Minas Padrão cheese against fungal contamination.

ABSTRACT

Spices are natural plant products, have been used not only as flavoring and coloring agents, but also as food preservatives and folk medicines throughout the world for thousands of years. Many spices also have been recognized by having both digestive stimulant and carminative actions and also antimicrobial, anti-inflammatory, antimutagenic and anti-carcinogenic potential. Antioxidant and genotoxic potential of species commonly used in Brazil was evaluated. The antioxidant activity was evaluated using different methods, including DPPH radical scavenging activity, ferric reducing power (FRAP), iron ion chelating power, inhibition of lipid peroxidation (TBARS), NO radical scavenging, and oxidative hemolysis inhibition. Furthermore, the antigenotoxic activity was evaluated through mitotic index and chromosome aberration in Allium cepa roots. Quantification of total phenols and flavonoids carried out. The results with the Ocimum basilicum spices in the DPPH test showed activity (82.01%), FRAP (321.12 uM ET and iron chelating activity (94.18) and for the Cinnamomum zeylanicum spice in the TBARS test (18.52%) evaluated by different methods and mechanisms of inactivation of free radicals and according to the evaluation of genotoxicity by the Allium cepa test the spices do not present genotoxic effects.


As especiarias são produtos vegetais naturais, que foram utilizados não só como agentes aromatizantes e colorantes, mas também como conservantes de alimentos e medicamentos populares em todo o mundo há milhares de anos. Muitas especiarias também foram reconhecidas por ter estimulantes digestivos e ações carminativas e também potencial antimicrobiano, anti-inflamatório, antimutagênico e anticarcinogênico. O potencial antioxidante e genotóxico das espécies comumente utilizadas no Brasil foi avaliado. A atividade antioxidante foi avaliada utilizando diferentes métodos, incluindo a atividade de eliminação de radicais DPPH, poder de redução férrica (FRAP), poder quelante de íons de ferro, inibição da peroxidação lipídica (TBARS), eliminação de radicais NO e inibição da hemólise oxidativa. Além disso, a atividade antigenotóxica foi avaliada através do índice mitótico e aberração cromossômica nas raízes do Allium cepa. Quantificação de fenóis totais e flavonoides realizados. Os resultados mostraram que as especiarias (Cinnamomum zeylanicum, Origanum vulgare, Piper nigrum, Zingiber officinale e Ocimum basilicum) apresentaram atividade antioxidante avaliada por diferentes métodos e mecanismos de inativação de radicais livres e de acordo com a avaliação de genotoxicidade pelo teste Allium cepa as especiarias não apresentam efeitos genotóxicos.

ABSTRACT

OBJECTIVES: This study was conducted to determine whether essential oils had anti-influenza A/WS/33 virus activity and whether there were specific compounds associated with this activity. METHODS: There were 63 essential oils evaluated for anti-influenza (A/WS/33 virus) activity using a cytopathic effect reduction method. The chemical composition of the anti-influenza essential oils was phytochemically analyzed by gas chromatography-mass spectrometry. RESULTS: The antiviral assays demonstrated that 11 of the 62 essential oils (100 μg/mL) possessed anti-influenza activity, reducing visible cytopathic effects of influenza A/WS/33 virus activity by > 30%. Furthermore, marjoram, clary sage and anise oils exhibited anti-influenza A/WS/33 virus activity of > 52.8%. However, oseltamivir (the anti-influenza A and B drug), showed cytotoxicity at the same concentration (100 μg/mL) as the essential oils. The chemical composition detected by GC–MS analysis, differed amongst the 3 most potent anti-viral essential oils (marjoram, clary sage and anise oils) except for linalool, which was detected in all 3 essential oils. CONCLUSION: This study demonstrated anti-influenza activity in 11 essential oils tested, with marjoram, clary sage and anise essential oils being the most effective at reducing visible cytopathic effects of the A/WS/33 virus. All 3 oils contained linalool, suggesting that this may have anti-influenza activity. Further investigation is needed to characterize the antiviral activity of linalool against influenza A/WS/33 virus.

ABSTRACT

Tetranychus urticae Koch (Acari: Tetranychidae) is a species of great economic importance to Brazil. In its control, the main option is the use of synthetic miticides, which, if used indiscriminately, can contaminate the environment, farmers and consumers. In the search for control alternatives, this study aimed to evaluate the effect of plant extracts and essential oils on females of this pest. For this, T. urticae females, reared in laboratory, were sprayed in Potter tower. Fourteen plants were tested in the form of aqueous extracts (AE), hydroethanolic extracts (HE) or essential oils (EO). The experimental plot consisted of a Petri dish with a Canavalia ensiformis L. leaf disk containing five T. urticae females, using ten plates per treatment. Mortality evaluations were performed 24, 48, 72, 96 and 120 hours after spraying, recording the number of dead females on the disc and the number of dead females on the moistened cotton. We considered that females found on cotton were repelled by treatments. Matricaria chamomilla L. HE and Pimpinella anisum L. AE have acaricidal effect for females, providing above 83% of mortality, after 120 hours. Origanum vulgare L. HE causes at least 75% mortality after 24 hours. Also 120 hours after spraying, P. anisum HE and O. vulgare AE cause repellency of females above 16%, and A. absinthium HE exceeds 22% for this parameter. The results stimulate further researches to determine the optimum dose and evaluation of additional effects on the fertility of surviving females.(AU)


Tetranychus urticae Koch (Acari: Tetranychidae) é uma espécie de grande importância econômica para o Brasil. Em seu controle, a principal opção são os acaricidas sintéticos, que, se usados de forma indiscriminada, podem contaminar ambiente, produtores e consumidores. Na busca de alternativas de controle, este trabalho teve por objetivo avaliar o efeito de extratos vegetais e óleos essenciais sobre fêmeas dessa praga. Para isso, fêmeas de T. ­urticae criadas em laboratório foram pulverizadas em torre de Potter. Foram testadas 14 espécies vegetais, na forma de extratos aquosos (EA), hidroetanólicos (EH) ou óleos essenciais (OE). A parcela experimental consistiu de uma placa de Petri com um disco de folha de feijão-de-porco (Canavalia ­ensiformis L.) contendo cinco fêmeas de T. urticae, sendo utilizadas dez placas por tratamento. As avaliações de mortalidade foram realizadas 24, 48, 72, 96 e 120 horas após a pulverização, registrando-se o número de fêmeas mortas no disco e no algodão umedecido. Considerou-se que fêmeas encontradas no algodão foram repelidas pelos tratamentos. Matricaria chamomilla L. na forma de extrato hidroetanólico e Pimpinella anisum L. na forma de extrato aquoso possuem efeito acaricida para fêmeas proporcionando acima de 83% de mortalidade, após 120 horas da pulverização. Origanum ­vulgare L. EH causa no mínimo 75% de mortalidade após 24 horas. Também após 120 horas, P. anisum EH e O. vulgare EA causam repelência de fêmeas acima de 16% e A. absinthium EH ultrapassa 22% para esse parâmetro. Os resultados estimulam a realização de pesquisas futuras para determinação da dose ótima e avaliação de efeitos adicionais sobre a fertilidade das fêmeas sobreviventes.(AU)

ABSTRACT

Antecedentes: la trasmisión de trazas de antibióticos en la carne, ha llevado a la prohibición de la utilización de alimentos con antibióticos promotores de crecimiento en las diferentes especies productivas para consumo humano. Por lo anterior, se hace necesario buscar nuevas alternativas que puedan remplazar la función que éstos desempeñan durante el proceso productivo. Objetivo: evaluar el perfil lipídico de pechugas en pollos de engorde de la línea genética Cobb500, luego de la administración Aceite Esencial de Orégano (Lippia origanoides) (AEO). Métodos: se utilizaron 200 pollos de línea genética Cobb500 y se realizó el muestreo de pechuga para el perfil lipídico, sólo el día 42. Los animales fueron aleatorizados a una de cinco dietas: dieta comercial con y sin antibiótico, dieta comercial sin antibiótico adicionada con diferentes niveles de AEO (75ppm, 100ppm o 200ppm AEO). Los animales fueron sacrificados a los 42 días de edad, y se realizó la toma de muestras de pechuga y contramuslo para determinar el perfil de ácidos grasos por cromatografía de gases. Se realizó un diseño estadístico de bloques al azar cada tratamiento tuvo un total de cuatro repeticiones; el análisis estadístico se realizó según el procedimiento GLM (Modelos Lineales Generales) del SAS. Resultados: el perfil lipídico en pechugas mostró resultados más sobresalientes en la dieta con mayor adición de AEO (0.72, C14:0; 29.1, C16:0; 6.01, C18:0). Conclusión: La adición de 200ppm de AEO (Lippia origanoides) en el alimento de pollos de engorde de la línea genética Cobb500 induce una mejora en la composición de ácidos grasos de su carne.


Background: the transmission of traces of antibiotics in meat, has led to the prohibition of the use of food with antibiotics growth promoters in the different productive species for human consumption. Therefore, it is necessary to look for new alternatives that can replace the function they perform during the production process. Objectives: to evaluate the lipid profile of breasts in broilers of the Cobb500 genetic line, after the administration of Essential Oil of Oregano (Lippia origanoides) (AEO). Methods: 200 chickens of Cobb500 genetic line were used. The animals were randomized to one of five diets: commercial diet with and without the addition of antibiotic, commercial diet without antibiotic added with three different levels of AEO (75ppm, 100ppm or 200ppm AEO). The animals were sacrificed at 42 days of age, and breast and thigh samples were taken to determine the fatty acid profile by gas chromatography. A statistical block design was performed randomly, each treatment had a total of four repetitions; the statistical analysis was performed according to the GLM (General Linear Models) procedure of the SAS. Results: the lipid profile in breasts showed more outstanding results in the diet with greater addition of AEO (0.72, C14: 0, 29.1, C16: 0, 6.01, C18: 0). Conclusions: the addition of 200ppm of AEO in the broiler feed of the Cobb500 genetic line induces an improvement in meat quality in the fatty acid composition of the broiler carcass.

ABSTRACT

INTRODUCTION: Asthma is an IgE-mediated inflammatory response characterized by hyperresponsiveness, airway inflammation, and reversible airflow obstruction. Currently, asthma affects 12 - 22% of the population in the Philippines. Anecdotal reports showed that yerba buena (Mentha arvensis Linn.) and oregano (Coleus amboinicus Lour.) are utilized for treating asthma in the folk culture.OBJECTIVE: The objective of this study was to determine the effect of combined Yerba Buena (Mentha arvensis Linn.) and Oregano (Coleus amboinicus Lour.) leaves extract in asthma-induced mice.METHODS:This study investigated the anti-asthmatic activity of the aqueous and methanolic extracts of the combined herbs in asthma-induced mice using immunoglobulin E (IgE) as a parameter.RESULTS: Aqueous- and methanol-treated mice has 50% and 60% reduction in the IgE level, respectively (p = 0.018). The extracts exhibited a significant (p = 0.001) anti-inflammatory activity in mice that further proved its effect on IgE. Moreover, lung histopathology also established the potential effect of the extract through the widening of the alveoli on treated mice.CONCLUSION: Combined Yerba Buena and Oregano aqueous and methanol extracts may have a potential health benefit against asthma.
