Myrcia is one of the largest genera of the economically important family Myrtaceae. Some of the species are used in folk medicine, such as a group known as “pedra-hume-caá” or “pedra-ume-caá” or “insulina vegetal” (insulin plant) that it is used for the treatment of diabetes. The species are an important source of essential oils, and most of the chemical studies on Myrcia describe the chemical composition of the essential oils, in which mono- and sesquiterpenes are predominant. The non-volatile compounds isolated from Myrcia are usually flavonoids, tannins, acetophenone derivatives and triterpenes. Anti-inflammatory, antinociceptive, antioxidant, antimicrobial activities have been described to Myrcia essential oils, while hypoglycemic, anti-hemorrhagic and antioxidant activities were attributed to the extracts. Flavonoid glucosides and acetophenone derivatives showed aldose reductase and α-glucosidase inhibition, and could explain the traditional use of Myrcia species to treat diabetes. Antimicrobial and anti-inflammatory are some of the activities observed for other isolated compounds from Myrcia.

“…Chemical constitutions of acorns of different Quercus species have disinfectant, antioxidant and antimicrobial properties and the decoctions of acorn peels have been used to heal burns and cuts. (Şöhretoğlu et al, 2014;Borges et al, 2013;Salminen et al, 2004).…”

“…It is shown that environmental factors such as altitude, latitude, precipitation, temperature, soil properties, and aspect would affect the synthesis of secondary metabolites. Amount of phenolic compounds can be influenced by developmental stage of the plant and different environmental factors such as soil composition, temperature, rainfall and ultraviolet radiation incidence, so that phenolic compounds and the other secondary metabolites show a chemical interface between plants and environment (Borges et al, 2013). Phytochemical compounds such as cuticular waxes, antifreeze polyols, and aromatics lead to acclimation to abiotic burdens, and some secondary metabolites such as aromatic alkaloids, furanocoumarins, flavonoids, phenylpropenoids and tannins may result in protection against both biotic and climatic effects (Alonso-Amelot et al, 2004).…”

Ebrahimi et al.: Population variability in Quercus brantiiAbstract. Persian Oak (Quercus brantii Lindl.) is one of the most important woody species of Zagros forests in western and southwestern Iran. In order to determine the variation of morphometry and total phenolic, flavonoid and tannin contents, ripen acorns from 27 populations of Q. brantii growing wild in nine regions of western and southwestern Iran were collected and examined. The amounts of total phenolic/tannin and flavonoid contents were determined by "Folin-Ciocalteu" and "Aluminum Chloride Colorimetric" methods, respectively. Significant differences in acorn morphometry were observed between the populations and regions, and the higher values of acorn morphometry belonged to four regions of Khuzestan province. Similarly, there also were significant differences in amounts of total phenolic, flavonoid and tannin contents between different populations and regions, and the higher amount of total phenolic, flavonoid and tannin contents were observed in populations from Khuzestan province. Different degrees of correlations were observed between the morphometery, total phenolics, flavonoids and tannins, and geographical and climatical factors. Cluster analysis and principle component analysis (PCA) based on the morphometric and phytochemical data resulted in detecting two major groups including: 1) populations from Khuzestan province, and 2) populations from adjacent provinces. Results of present study showed that morphology and amounts of total phenolic, flavonoid and tannin contents of Q. brantii acorns are significantly influenced by environmental factors of their original provenances.

“…Os limites de detecção (0,0006 mg mL Na literatura científica há descrição desse mesmo método espectrofotométrico para quantificar polifenóis em plantas medicinais (Sampaio et al, 2011;Borges et al, 2012;Alcântara et al, 2012) e outro estudo descreveu método semelhante (Brighenti et al, 2007), entretanto a validação analítica não foi demonstrada. Além disso, encontrou-se um trabalho que emprega a cromatografia líquida de alta eficiência para a análise da catuaba (Beltrame et al, 2006), porém, embora seja esse um método analítico mais sensível e específico, é de custo mais elevado.…”

RESUMO:Trichillia catigua A. Juss. é uma planta medicinal utilizada principalmente como estimulante, possivelmente devido à presença de fenóis. Entre os métodos utilizados para a determinação de polifenóis em matérias-primas vegetais destaca-se a análise por meio de ensaios espectrofotométricos por apresentarem boa sensibilidade, simplicidade, e ter custos mais acessíveis. O presente trabalho teve o objetivo de validar a metodologia analítica para determinação de polifenóis na casca de catuaba em pó. Utilizou-se o método de Hagerman & Butler para a quantificação dos polifenóis totais encontrando-se 7,96%. O método validado mostrou-se simples, rápido, seletivo, linear, exato, preciso, e robusto para ser executado na rotina de laboratório de controle de qualidade, constituindo uma possibilidade de análise desta planta medicinal. Palavras-chave:Trichillia catigua, planta medicinal, controle de qualidade, validação.ABSTRACT: Quantification of total phenols present in the bark of Trichilia catigua A. Juss (Meliaceae). Trichilia catigua A. Juss. is a medicinal plant used especially as a stimulant, possibly due to the presence of phenols. Among the methods used for the determination of polyphenols in raw plant materials is analysis through spectrophotometric assays since they have good sensitivity, are simple and more affordable. This study aimed to validate the analytical methodology for the determination of polyphenols in the bark of powder "catuaba". The method of Hagerman & Butler was employed in the quantification of total polyphenols, yielding 7.96%. The validated method has proven to be simple, rapid, selective, linear, accurate, precise and robust to be performed in the routine of a laboratory of quality control, constituting a possibility for the analysis of this medicinal plant.
