ABSTRACT

ABSTRACT Objective: To evaluate the effect of ginger with P6 acupressure in preventing and treating chemotherapy-induced nausea and vomiting (CINV) in cancer patients. Method: A total of 172 participants were randomly divided into the control, ginger, acupressure, and joint groups, who were hospitalized in the Affiliated Hospital of Xuzhou Medical University from February and September 2022. The baseline characteristics, nausea, vomiting, and retching, benefit finding, functional living index-emesis, treatment satisfaction, and adverse reaction, were used in data collection. Results: No significant difference was found in benefit finding and adverse reactions among the four groups (P > 0.05). Ginger significantly improved delayed CINV and function living index-nausea (P < 0.05) but had no significant effect on acute CINV, retching, and delayed vomiting, functional living index-emesis, and treatment satisfaction (P>0.05). Acute nausea and retching, delayed nausea, vomiting, and retching, functional living index-emesis, and treatment satisfaction were effectively improved in the acupressure and joint groups (P < 0.05). Conclusion: Ginger with P6 acupressure may contribute to improving CINV in patients undergoing chemotherapy.

ABSTRACT

The weight coefficients of appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol were determined by analytic hierarchy process(AHP), criteria importance though intercrieria correlation(CRITIC), and AHP-CRITIC weighting method, and the comprehensive scores were calculated. The effects of ginger juice dosage, moistening time, proces-sing temperature, and processing time on the quality of Magnoliae Officinalis Cortex(MOC) were investigated, and Box-Behnken design was employed to optimize the process parameters. To reveal the processing mechanism, MOC, ginger juice-processed Magnoliae Officinalis Cortex(GMOC), and water-processed Magnoliae Officinalis Cortex(WMOC) were compared. The results showed that the weight coefficients of the appearance traits, extract yield of standard decoction, and total content of honokiol and magnolol determined by AHP-CRITIC weighting method were 0.134, 0.287, and 0.579, respectively. The optimal processing parameters of GMOC were ginger juice dosage of 8%, moistening time of 120 min, and processing at 100 ℃ for 7 min. The content of syringoside and magnolflorine in MOC decreased after processing, and the content of honokiol and magnolol followed the trend of GMOC>MOC>WMOC, which suggested that the change in clinical efficacy of MOC after processing was associated with the changes of chemical composition. The optimized processing technology is stable and feasible and provides references for the modern production and processing of MOC.

ABSTRACT

This study aimed to investigate the impact of ginger juice on chemical profile of Magnoliae Officinalis Cortex(MOC) when they were processed together. Ultra-high-performance liquid chromatography coupled to quadrupole-orbitrap high-resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) was used for qualitative analysis of the chemical component of MOC samples before and after being processed with ginger juice. UPLC was performed to observe the content variation of eight main components in processed MOC. A total of 174 compounds were identified or tentatively deduced from processed and unprocessed MOC samples according to MS data obtained in positive and negative ion mode. After MOC was processed with ginger juice, the peak areas of most phenolics increased, while the peak areas of most phenylethanoid glycosides decreased; as for neolignans, oxyneolignans, other lignans and alkaloids, changes in the peak area were variable, and the peak areas of terpenoid-lignans varied little. Additionally, gingerols and diarylheptanoids were only detected in the processed MOC sample. The contents of syringin, magnoloside A, and magnoloside B decreased significantly in the processed MOC sample while no significant difference was observed in the contents of magnoflorine, magnocurarine, honokiol, obovatol, and magnolol. This study comprehensively explored the content variation of chemical components in processed and unprocessed MOC samples derived from different regions and with different tree ages using UPLC and UHPLC-Q-Orbitrap HRMS, and summarized the variation characteristics of various compounds. The results provide a data foundation for further research on pharmacodynamic substances of MOC processed with ginger juice.

ABSTRACT

This study compared the changes in chemical components during the processing of different types of Aconiti Lateralis Radix Praeparata(ALRP) in "Jianchang" faction, i.e., dried ginger-steamed ALRP pieces(Yin-FP), sand-fried ALRP pieces(Yang-FP), and rice swill water-bleached ALRP pieces(DFP), and provided a scientific basis for the mechanism in toxicity reduction and efficacy enhancement from a compositional perspective. Samples were collected during the processing of the three types of ALRP pieces, yielding raw ALRP pieces, water-bleached Yin-FP, ginger juice-moistened Yin-FP, steamed Yin-FP, water-bleached Yang-FP, sand-fried Yang-FP, water-bleached DFP, rice swill water-bleached DFP, and roasted DFP. Aconitine, mesaconitine, hypaconitine, benzoylaconine, benzoylmesaconine, benzoylhypaconine, aconine, mesaconine, hypaconine, salsolinol, fuziline, and higenamine in the extracts were determined by UPLC-MS/MS, and then content analysis and cluster heatmap analysis were performed on 11 sets of samples. During the processing of the three types of ALRP pieces, bleaching significantly reduced the content of 12 alkaloids; steaming, stir-frying, and roasting significantly reduced the content of diester-type alkaloids(aconitine, mesaconitine, and hypaconitine) and significantly increased the content of monoester-type alkaloids(benzoylaconine, benzoylmesaconine, and benzoylhypaconine) and aminoalcohol-type alkaloids(aconine, mesaconine, and hypaconine). During the processing of Yin-FP, the diester-type alkaloids continuously decreased, while the monoester-type and aminoalcohol-type alkaloids showed an initial decrease followed by an increase. During the processing of Yin-FP, Yang-FP, and DFP, the diester-type alkaloids continuously decreased, while the monoester-type and aminoalcohol-type alkaloids showed an initial decrease followed by an increase. Steamed Yin-FP showed a higher increase in content than fried Yang-FP and roasted DFP. Comprehensive analysis of content differences in toxic and therapeutic components in three ALRP pieces suggests that the distinctive processing methods in "Jianchang" faction can indeed achieve detoxification and efficacy enhancement on ALRP. This study provides references for understanding the mechanisms of action of the three processing methods.

ABSTRACT

Abstract The current study aimed to determine the effects of different levels of Zingiber officinale as a herbal feed additive on growth performance, carcass characteristic, serum biochemistry, total bacterial count (TBC), gut morphology, and immunological parameters of broilers. A total of 1500, day-old broiler chicks (Hubbard) were equally accredited to five treatment groups, each with six replicates (50 birds/replicate). Five experimental diets were prepared using basal diet i.e. with antibiotics positive control (PC), 3 g/kg ginger (group A), 6 g/kg ginger (group B), 9 g/kg ginger (group C) and without antibiotics negative control (NC). Group A and C showed significantly (p<0.05) higher feed intake (FI) as compared to other groups. Group C showed significantly (p<0.05) lower Total bacterial count (TBC) followed by group B as compared to NC. Carcass characteristics showed non-significant effects among different treatments. Mean villi length and width were significantly (p <0.05) higher in all ginger supplemented groups as compared to the control groups. Blood serum parameters including cholesterol, triglycerides, and low-density lipoproteins (LDL) were significantly (p<0.05) lower in groups B and C in comparison with the control groups. Whereas high-density lipoproteins (HDL) was significantly higher in group B as compared to the others. In conclusion, ginger supplementation @0.6% in the basal diet significantly improved growth performance and gut morphometry of broilers. It also showed a positive impact on cholesterol, triglycerides and gut microbes. Therefore, ginger could be a better substitute for antibiotic growth promoters.

Um total de 1.500 pintos de corte de um dia de idade (Hubbard) foram igualmente credenciados em cinco grupos de tratamento, cada um com seis repetições (50 aves/repetição). Cinco dietas experimentais foram preparadas usando dieta basal, ou seja, com controle positivo de antibióticos (PC), 3 g/kg de gengibre (grupo A), 6 g/kg de gengibre (grupo B), 9 g/kg de gengibre (grupo C) e sem controle negativo de antibióticos (NC). Os grupos A e C apresentaram consumo de ração (FI) significativamente (p < 0,05) maior do que os outros grupos. O grupo C apresentou contagem bacteriana total (CBT) significativamente menor (p < 0,05) seguido pelo grupo B em comparação com o NC. As características da carcaça apresentaram efeitos não significativos entre os diferentes tratamentos. O comprimento e largura médios das vilosidades foram significativamente (p < 0,05) maiores em todos os grupos suplementados com gengibre em comparação com os grupos de controle. Os parâmetros séricos do sangue, incluindo colesterol, triglicerídeos e lipoproteínas de baixa densidade (LDL), foram significativamente (p < 0,05) menores nos grupos B e C em comparação com os grupos controle. Enquanto as lipoproteínas de alta densidade (HDL) foram significativamente maiores no grupo B em comparação com os outros. Em conclusão, a suplementação de gengibre a 0,6% na dieta basal melhorou significativamente o desempenho de crescimento e a morfometria intestinal de frangos de corte. Ele também mostrou um impacto positivo sobre o colesterol, triglicerídeos e micróbios intestinais. Portanto, o gengibre pode ser um substituto melhor para os promotores de crescimento com antibióticos.

ABSTRACT

Nos últimos anos, a obesidade vem aumentando consideravelmente entre adultos e crianças e, segundo a OMS, estima-se que em 2025 o número de obesos ultrapasse a 2,3 milhões em todo o mundo. O indivíduo obeso apresenta maiores riscos de desenvolver doenças crônicas não transmissíveis, como diabetes, doenças cardiovasculares, dislipidemias e ainda alguns tipos de cânceres. O tratamento para a obesidade é variado e inclui mudanças no estilo de vida como: hábitos alimentares e prática de atividade física, tratamento medicamentoso, cirurgia bariátrica e fitoterápicos com o potencial de auxiliar no tratamento. O objetivo deste trabalho foi realizar uma revisão bibliográfica a fim de avaliar os benefícios da utilização de medicamentos fitoterápicos como auxiliar no tratamento da obesidade, seus principais ativos, mecanismos de ação e sua utilização popular. Dentre as plantas pesquisadas e que demonstraram potencial para atuar no tratamento da obesidade encontram-se Camelia sinensis, Citrus aurantium, Hibiscus sabdariffa, Coffea arabica, Ephedra sinica, Zingiber oficinale e Senna alexandrina. Os principais mecanismos de ação envolvidos no potencial anti-obesidade das plantas medicinais são a capacidade de controle do apetite e ingestão de energia, estímulo da termogênese, inibição da lipase pancreática e redução da absorção de gordura, diminuição da lipogênese e aumento da lipólise. Desta forma, conclui-se que as plantas selecionadas neste estudo apresentaram efeitos positivos nos parâmetros bioquímicos e físicos, podendo ser incluídas nos protocolos como coadjuvantes nos tratamentos de emagrecimento.


In recent years, obesity has increased considerably among adults and children and according to the WHO, it is estimated that in 2025 the number of obese people will exceed 2.3 million worldwide. The obese individual is at greater risk of developing non-communicable chronic diseases, such as diabetes, cardiovascular disease, dyslipidemia and even some types of cancer. The treatment for obesity is varied, including changes in lifestyle such as eating habits and physical activity, drug treatment, bariatric surgery and phytotherapy with the potential to aid in the treatment. The objective of this work was to carry out a literature review, evaluating the benefits of using herbal medicines as an aid in the treatment of obesity, their main assets, mechanisms of action and their popular use. Among the plants researched and that have shown potential to act in the treatment of obesity are Camelia sinensis, Citrus aurantium, Hibiscus sabdariffa, Coffea arabica, Ephedra sinica, Zingiber officiale and Senna alexandrina. The main mechanisms of action involved in the antiobesity potential of medicinal plants are the ability to control appetite and energy intake, thermogenesis stimulation, pancreatic lipase inhibition and reduction of fat absorption, lipogenesis decrease and lipolysis increase. Thus, it is concluded that the plants selected in this study showed positive effects on biochemical and physical parameters, and can be included in the protocols as adjuvants in weight loss treatments.

ABSTRACT

Ginger moxibustion has the effect of regulating zang-fu organs and activating qi and blood circulation. When used, ginger paste is required to be close to human skin. Currently, the ginger box used clinically in the hospital can't meet the requirement of large area fitting human skin, and the efficacy of ginger moxibustion is significantly reduced. In this study, a flexible ginger paste box was proposed, which was composed of flexible components polydimethylsiloxane (PDMS), spring and wire netting. The large flexibility of the structure made it fit well with human skin. Finite element method was used to study the fitting degree between ginger paste box and waist soft tissue. Finite element models of flexible ginger paste box and waist soft tissue were established based on Hypermesh and Abaqus software. The equivalent contact area between the flexible ginger paste box and waist was obtained by numerical simulation under different PDMS unilateral thickness, spring wire diameter, wire netting diameter and ginger paste layer thickness. The four parameters were taken as the influencing factors, and the equivalent contact area was taken as the optimization objective. The typical value analysis and variance analysis of S/N were performed by Taguchi method, and the results showed that among the four influencing factors, the wire netting diameter had the largest influence on equivalent contact area and its contribution rate reached 41.98%. The contribution rates of PDMS unilateral thickness, spring wire diameter and ginger paste layer thickness reached 36.48%, 13.97% and 6.50%, respectively. The optimized PDMS unilateral thickness, spring wire diameter, wire netting diameter and ginger paste layer thickness were 1.5, 0.4, 0.15, 35 mm, respectively, and the equivalent contact area was 95.60 cm 2. The optimized flexible ginger paste box with great fitting performance can improve the effect of ginger moxibustion.

ABSTRACT

Based on the previous research results of our group and literature research, the chemical components, mechanisms, pharmacodynamics, and pharmacokinetics of Zingiberis Rhizoma Carbonisata were summarized to determine the quality markers(Q-markers) of Zingiberis Rhizoma Carbonisata and Zingiberis Rhizoma. Our research group has clarified the differential components of Zingiberis Rhizoma Carbonisata and Zingiberis Rhizoma, the meridian-warming hemostatic effect of Zingiberis Rhizoma Carbonisata, the related targets and pathways of the effect, the endogenous biomarkers of Zingiberis Rhizoma Carbonisata, and the hemodynamic processes of Zingiberis Rhizoma Carbonisata and Zingiberis Rhizoma. Moreover, based on high-performance liquid chromatography-diode array detector-electrospray ionization mass spectrometry(HPLC-DAD-ESIMS), a method for determining the content of Q-mar-kers was established. In conclusion, the study finally determined that gingerone, 6-shogaol, and diacetyl-6-gingerol were the Q-mar-kers of Zingiberis Rhizoma Carbonisata decoction pieces, and 6-gingerol, 8-gingerol, and 10-gingerol were Q-markers of Zingiberis Rhizoma decoction pieces. The result is expected to provide a reference for the establishment of quality standards for Zingiberis Rhizoma Carbonisata decoction pieces and Zingiberis Rhizoma decoction pieces.

ABSTRACT

This study was aimed to explore the effect of Zingiberis Rhizoma extract on rats with antibiotic-associated diarrhea(AAD), and reveal the modulation of gut microbiota during alleviation of AAD. AAD rat model was successfully established by exposing rats to appropriate antibiotic mixed solution. Peficon(70 mg·kg~(-1)·d~(-1)) was used as positive control, then rats were treated with 200 mg·kg~(-1)·d~(-1) and 400 mg·kg~(-1)·d~(-1) of Zingiberis Rhizoma extract for low and high dosage groups of Zingiberis Rhizoma extract, respectively. The weight changes of the rats were observed, and the degree of diarrhea were evaluated by fecal score, 120 min fecal weight and fecal water content. Colon tissues for histopathological examination were stained with hematoxylin and eosin(HE), and 16 S rRNA sequencing analysis of gut microbiota was performed. The results showed that compared with the model group, the degree of diarrhea, indicated by fecal water content, fecal score, and 120 min fecal weight of positive control group, Zingiberis Rhizoma low-dose group and Zingiberis Rhizoma high-dose group were significantly ameliorated. And the treatment of Zingiberis Rhizoma could significantly improve the pathological condition of colon tissue in AAD rats, especially the high dose of Zingiberis Rhizoma. In addition, 16 S rRNA sequencing analysis of gut microbiota showed that the diversity and abundance of gut microbiota were significantly improved and the reco-very of gut microbiota was accelerated after given high-dose of Zingiberis Rhizoma, while no significant changes of alterations were observed after given Pefikon. Of note, compared with the pefikon group, the abundance and diversity of gut microbiota in Zingi-beris Rhizoma high-dose group were significantly elevated. At the phylum level, the abundance of Firmicutes in AAD rats increased and the abundance of Proteobacteria was decreased after the Zingiberis Rhizoma intervention. At the genus level, the abundance of Bacillus spp., Lachnoclostridium and Escherichia coli-Shigella were decreased, and the abundance of Lactobacillus spp., Trichophyton spp., and Trichophyton spp., etc., were increased. While compared with the AAD model group, there was no significant difference of gut microbiota after given Peficon. The results showed that Zingiberis Rhizoma exerted beneficial health effects against AAD, and positively affected the microbial environment in the gut of rats with AAD.

ABSTRACT

The present study investigated the chemical profiles and evaluated the inhibitory effect against 5-Lipoxygenase (5-Lox) activity for extracts of ginger rhizome, callus, and callus treated with the elicitors; yeast extract (100, 300 and 500 mg/L), glycine (100, 200 and 300 mg/L) and salicylic acid (100 and 200 mg/L). Oils and chloroform: methanol (CM) extracts were prepared by maceration in petroleum ether and CM (1:1, v/v), respectively. Chemical profiles were determined by gas chromatography/mass spectrometry (GC/MS) analysis. Oil of the callus recorded higher 5-Lox inhibitory effect (IC50 58.33±4.66 µg/mL) than the oil of rhizome (IC50168.34±15.64 µg/mL) and comparable to that of the positive control; Nordihydroguaiaretic acid (IC50 61.25±1.02 µg/mL). The chemical profile of the callus oil contained large amounts of fatty acids, mainly the unsaturated fatty acid oleic acid (31.11%) and saturated fatty acid palmitic acid (28.56%). Elicitors modified the chemical profile of the callus and ameliorated the anti-5-Lox activity of CM extract of the callus. CM extracts of callus treated with 100 and 300 mg/L yeast extract and 50 mg/L salicylic acid significantly suppressed (P ≤ 0.05) the 5-Lox activity by 33.16%, 25.46% and 16%, respectively as compared to the CM extract of untreated callus. In conclusion, ginger callus could be considered as a valuable dietary supplement in the treatment of various inflammatory disorders.


O presente estudo teve como objetivo investigar os perfis químicos e avaliar o efeito inibitório da atividade da 5-Lipoxigenase (5-Lox) em extratos de rizoma, calo e calo de gengibre tratados com os eliciadores; extrato de levedura (100, 300 e 500 mg / L), glicina (100, 200 e 300 mg / L) e ácido salicílico (100 e 200 mg / L). Extratos de óleos e clorofórmio: metanol (CM) foram preparados por maceração em éter e CM (1: 1, v / v), respectivamente. Os perfis químicos foram determinados por análise de cromatografia gasosa / espectrometria de massa (GC / MS). O óleo do calo registrou maior efeito inibitório de 5-Lox (IC50 58,33 ± 4,66 µg / mL) do que o óleo de rizoma (IC50168,34 ± 15,64 µg / mL) e comparável ao do controle positivo; Ácido nordi-hidroguaiarético (IC50 61,25 ± 1,02 µg / mL). O perfil químico do óleo de calo continha grandes quantidades de ácidos graxos, principalmente o ácido graxo insaturado ácido oleico (31,11%) e ácido graxo saturado palmítico (28,56%). Os elicitores modificaram o perfil químico do calo e melhoraram a atividade anti-5-Lox do extrato de CM do calo. Extratos de CM de calos tratados com 100 e 300 mg / L de extrato de levedura e 50 mg / L de ácido salicílico suprimiram significativamente (P ≤ 0,05) a atividade de 5-Lox em 33,16%, 25,46% e 16%, respectivamente, em comparação com o extrato de CM de calo não tratado. Em conclusão, o calo de gengibre pode ser considerado um suplemento dietético valioso no tratamento de vários distúrbios inflamatórios.

ABSTRACT

Aiming to solve the poor compactibility of the alcoholic extract of Zingiberis Rhizoma(ZR), this study explored the feasibility of its physical modification using co-spray drying with a small amount of hydroxypropyl methyl cellulose(HPMC). Based on the univariate analysis, the influence of two independent variables(the HPMC content in the product and the solid content of spray material) on the powder properties and tablet properties of the dried product was investigated by the central composite design. With the tensile strength and disintegration time of the tablets as the evaluation indexes, the optimal prescription was determined as follows: the HPMC content was 15% and the solid content of spray material was 25.6%. The accuracy of the regression model established for predicting tensile strength and disintegration time of tablets was verified, and the results revealed that the measured values were close to the predicted ones with deviations of 0.47% and-8.2%, indicating good prediction and reproducibility of the model. The tensile strength(4.24 MPa) of tablets prepared with the optimal prescription was 3.59 times that(1.18 MPa, far lower than the baseline of 2 MPa for qualified tablets) with the spray-dried powder of the ZR. On the other hand, due to the addition of HPMC, the disintegration time of tablets increased from 7.3 min to 24.6 min. On the whole, this study provided a new strategy to solve the common problem of poor compactibility of raw Chinese medicinal materials, which facilitated the successful preparation of Chinese medicinal tablets with high drug loads.

ABSTRACT

O objetivo deste trabalho foi avaliar a presença de matérias estranhas em noz-moscada, (Myristica fragrans Houttuyn), cúrcuma (Curcuma longa Linnaeus), gengibre (Zingiber officinale Roscoe), colorífico (mistura de urucum [Bixa orellana Linnaeus] com fubá), pimenta-do-reino (Piper nigrum Linnaeus) e páprica (Capsicum annuum Linnaeus) conforme a legislação sanitária. Foram analisadas 180 amostras empregando os métodos preconizados pela AOAC International, de maio de 2018 a maio de 2020. A presença de ao menos uma matéria estranha foi observada em 80% das amostras. Pelos animais foram observados em todos os produtos e fragmentos de insetos foram encontrados na maioria das amostras. Ácaro, inseto inteiro, larva de inseto, bárbula e exúvia também foram encontrados, além de fibras sintéticas e fragmentos de microplásticos. Quanto à legislação, 47,8% das amostras estavam acima dos limites de tolerância, destas, 90,7% por conterem matérias estranhas indicativas de falhas na aplicação das boas práticas e 9,3% por matérias estranhas indicativas de risco à saúde. Os resultados obtidos denotam ineficiência da aplicação das medidas de boas práticas na cadeia produtiva e alertam para a intensificação da fiscalização direcionada ao cumprimento das normas sanitárias, além de provocarem a reflexão sobre a necessidade de alterações na legislação referente às matérias estranhas. (AU)


The aim of this work was to evaluate the presence of foreign matter in nutmeg, (Myristica fragrans Houttuyn), turmeric (Curcuma longa Linnaeus), ginger (Zingiber officinale Roscoe), colorific (mixture of annatto [Bixa orellana Linnaeus] with cornmeal), black pepper (Piper nigrum Linnaeus) and paprika (Capsicum annuum Linnaeus) according to the health legislation. A total of 180 samples were analyzed using the methods recommended by AOAC International, from May 2018 to May 2020. The presence of at least one foreign matter was observed in 80% of the samples. Animal's hairs were observed in all the evaluated products and insect's fragments were found in the most of the samples. Mites, whole insects, insect larvae, barbules and exuvia were also found, as wellas synthetic fibers and microplastic fragments. About legislation, 47.8% of the samples were above the tolerance limits, of these, 90.7% for containing foreign matters indicating failure of good practices and 9.3% for foreign matters indicating health risk. The results obtained show inefficiency in the application of good practice measures in production chain and advertise for the intensification of inspection directed to fulfillment of sanitary norms, besides provoking the reflection on the necessity of alterations in the legislation about foreign matter in foods.

ABSTRACT

Especiarias são produtos constituídos de partes de espécies vegetais com importante valor alimentício e diversos benefícios para a saúde. O objetivo deste trabalho foi pesquisar adulterações na composição de cúrcuma (Curcuma longa Linnaeus), gengibre (Zingiber officinale Roscoe), noz-moscada (Myristica fragrans Houttuyn), páprica (Capsicum annuum Linnaeus), pimenta-do-reino (Piper nigrum Linnaeus) e colorífico (mistura de urucum, Bixa orellana Linnaeus, com fubá). Foram analisadas 180 amostras adquiridas em municípios do estado de São Paulo. A investigação dos elementos histológicos foi feita por microscopia óptica, a análise dos corantes por cromatografia em papel e a quantificação da bixina por cromatografia líquida de alta eficiência. Das amostras analisadas, 16,1% apresentaram elementos histológicos estranhos ao produto, sendo que nenhuma amostra apresentou corante orgânico artificial. A concentração de bixina nas amostras de colorífico variou entre 0,6 e 105,3 mg/100g, com média de 18,9 mg/100g e desvio padrão de 17,7 mg/100g. A avaliação microscópica revelou que a maioria das adulterações ocorre pela adição de amido de Zea mays. O colorífico não apresentou adulterações, porém foi constatada a necessidade de uma padronização da concentração de bixina. Este estudo demonstrou a necessidade da intensificação do monitoramento de adulterações em especiarias para que a comercialização de alimentos fidedignos seja garantida. (AU)


Spices are products made up of parts of plant species, with important nutritional value and many health benefits. The aim of this work was to evaluate adulterations in turmeric (Curcuma longa Linnaeus), ginger (Zingiber officinale Roscoe), nutmeg (Myristica fragrans Houttuyn), paprika (Capsicum annuum Linnaeus), black pepper (Piper nigrumLinnaeus) and colorific (mixture containing Bixa orellana with cornmeal). A total of 180 samples purchased in the municipalities of the state of São Paulo were analyzed. The investigation of the histological elements was performed by optical microscopy, the analysis of the dyes was carried out using paper chromatography and the quantification of the bixin was performance by high performance liquid chromatography. Of the 180 samples analyzed, 16.1% presented strange histological elements, classified as adulterations. Among the adulterated samples, none showed organic dye. Bixin analysis was carried out on colorific samples, ranging from 0.6 ­ 105.3 mg/100g, with an average of 18.9 mg/100g and standard deviation of 17.7 mg/100g, demonstrating the need to regulate the annatto extract concentration range added into the condiment. The evaluation demonstrated the necessity to monitor adulteration in spices, so that producers and merchants provide food with quality to the consumer. (AU)

ABSTRACT

In order to achieve good yields and profitability from ginger crops, the water supply must be adequate. However, there are few studies available which have evaluated the adequate water supply to this vegetable. The objective of this study was to evaluate the effect of different irrigation depths on the development and productivity of ginger plants. The research was conducted at the "Sítio Schmidt" farm located in the municipality of Santa Maria de Jetibá, in the central mountainous region of Espírito Santo State, Brazil. The experimental design was a randomized block design with four replications, each experimental unit consisting of three rows at a spacing of 0.90 m and 0.10 m between plants of two meters extension, totaling 20 experimental units. The treatments consisted of application of five irrigation depths equivalent to: 50%, 75%, 100%, 125% and 150% of crop evapotranspiration (ETc). We evaluated the number of sprouts; average mass of export quality rhizome; the production of export, small and total rhizomes (t ha-1); and water use efficiency. The total water depth applied in the range 1100­1200 mm per cycle favors the development of ginger plants, providing the highest yields of total and export rhizomes, the greatest average mass of export quality rhizome and lowest production of small rhizomes.


Para que se alcance bons rendimentos e lucratividade com a cultura do gengibre o fornecimento de água deve ser adequado. Entretanto, ainda são poucos os trabalhos que avaliam o adequado fornecimento de água para esta hortaliça. Frente a isso, objetivou-se avaliar o efeito de diferentes lâminas de irrigação no desenvolvimento e na produtividade da cultura do gengibre. A pesquisa foi conduzida na propriedade "Sítio Schmidt" localizada no município de Santa Maria de Jetibá, região Central Serrana do Estado do Espírito Santo. O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições, sendo cada unidade experimental constituída por três fileiras em um espaçamento de 0,90 m e 0,10 m entre plantas de dois metros de extensão, totalizando 20 unidades experimentais. Os tratamentos consistiram na aplicação de cinco lâminas de irrigação, sendo elas: 50%, 75%, 100%, 125% e 150%. Foram avaliados o número de brotações; a massa média dos rizomas com padrão tipo exportação; as produtividades de rizomas tipo exportação, pequeno e total (t ha-1); e a eficiência do uso da água. A lâmina total aplicada na faixa de 1100-1200 mm por ciclo, ou seja, 75 a 100% da ETc favorece o desenvolvimento de plantas de gengibre, proporcionando maiores produtividades de rizoma total e tipo exportação, maior massa média de rizoma tipo exportação e menor produção de rizomas pequenos.

ABSTRACT

Purpose: evaluate the antimicrobial activity of intracanal dressings and their influence on dentinal colour changes. Material and methods: eighty single-rooted human extracted teeth were decoronated and divided into eight groups (n=10) according to intracanal dressing protocols inserted into the root canals: G1­distilled water (DW); G2­2% chlorhexidine gel (CHX); G3­calcium hydroxide (Ca[OH]2)+DW; G4­grape seed extract (GSE)+DW; G5­ginger extract (GE)+DW; G6­Ca(OH)2+CHX; G7­GSE+CHX; and G8­GE+CHX. The antimicrobial activity was evaluated by colony-forming units (CFUs) counting and dentinal colour changes was evaluated by digital spectrophotometry. Data were statistically analysed by One-way ANOVA followed by Tukey´s post hoc test (antimicrobial evaluation) and non-parametric Wilcoxon followed by the Mann- Whitney-U test (colour change evaluation) (α=0.05). Results: the highest bacterial reduction was observed in groups 4, 6, 7 and 8, with no significant difference between them (p<0.05). Groups 4 and 7 showed the highest medians of dentinal colour change (p<0.05). Conclusion: the addition of CHX improved the antimicrobial activity of GE-based intracanal dressing, with no effect in GSE-based intracanal dressing; moreover, these protocols induced significant dentinal colour changes. (AU)


Objetivo: avaliar a atividade antimicrobiana de medicações intracanais e sua influência na alteração da cor dentinária. Materiais e métodos: oitenta dentes humanos extraídos unirradiculares foram seccionados e divididos em oito grupos (n = 10), de acordo com os protocolos de medicação intracanal inseridos nos canais radiculares: água destilada G1 (DW); G2-2% de gel de clorexidina (CHX); hidróxido de cálcio G3 ­ (Ca [OH] 2) + DW; extrato de semente de uva G4 (GSE) + DW; extrato de gengibre G5 (GE) + DW; G6- Ca (OH) 2 + CHX; G7 ­ GSE + CHX; e G8-GE + CHX. A atividade antimicrobiana foi avaliada por contagem de unidades formadoras de colônias (UFCs) e as alterações de cor dentinária foram avaliadas por espectrofotometria digital. Os dados foram analisados estatisticamente por ANOVA one-way, seguida pelo teste post hoc de Tukey (avaliação antimicrobiana) e Wilcoxon não paramétrico, seguido pelo teste de Mann- Whitney-U (avaliação da mudança de cor) (α = 0,05). Resultados: a maior redução bacteriana foi observada nos grupos 4, 6, 7 e 8, sem diferença significativa entre eles (p < 0,05). Os grupos 4 e 7 apresentaram as maiores medianas da alteração da cor dentinária (p < 0,05). Conclusão: a adição de CHX melhorou a atividade antimicrobiana da medicação intracanal baseado em GE, sem efeito na medicação intracanal baseado em GSE; além disso, esses protocolos induziram alterações significativas na cor dentinária.(AU)
