ABORDAGEM FITOQUÍMICA DO EXTRATO ETANÓLICO DA CASCA DE Myroxylon peruiferum L.f

Abstract

_______________________________________________________ RESUMOO uso de produtos naturais com propriedades terapêuticas é tão antigo quanto à civilização humana e, por um longo período, minerais, plantas e produtos animais eram fundamentais PHYCHOCHEMICAL APPROACH OF THE ETHANOLIC EXTRACT OF THEMyroxylon peruiferum L.f _______________________________________________________ ABSTRACTThe use of natural products with therapeutic properties is as old as the human civilization and for a long period, mineral, plant and animal products were essential sources of drugs. Myroxylon peruiferum L. f. belongs to Fabaceae family and is popularly known as balm. This study aimed to evaluate the phytochemical properties of the ethanol extract of M. peruiferum L.f. bark. The phytochemical properties of the extract were determined by standard methods described by Matos. The determination of antioxidant activity was based on the free radical DPPH scanning method. For quantification of flavonoids, followed the methodology proposed by Funari and Ferro. The results demonstrate that the balsam shell contains a wide availability of iron and ascorbic acid (vitamin C). The extract has tannins, flavonoids, triterpenoids and saponins. Regarding the DPPH, the ethanol extract showed a good antioxidant capacity against radical. The results demonstrate the chemical potential, as well as justify their use in folk medicine for the treatment of diseases.

Identificação de metabólitos secundários em extrato hidroetanólico foliar de Libidibia ferrea (Mart. ex Tul.) L.P. Queiroz

“…Os esteroides vegetais observados, são citados na literatura por deterem propriedades antitumorais, antimicrobianas e hormonais (Guimarães et al, 2014). Enquanto os compostos pertencentes às saponinas além de apresentarem ação antioxidante e antifúngica, possuem atividade citotóxica contra tumores (Pereira et al, 2018).…”

Antioxidant Evaluation of the Aqueous Extract of Hulls of Campsiandra laurifolia in Colitis Induced by Acetic Acid in Wistar Rats

“…Tannins also help to reduce the inflammatory process through the formation of a protective layer on the damaged skin or mucosa, with processes of epithelial restructuring and vessel formation. [27][28][29][30][31] Colitis is related to oxidative damage by increasing FRs of oxygen and nitrogen that cause cell destruction, inflammatory infiltrate and the release of mediators, such as cytokines, potentiating stress. The oxygen FRs induce the LPO process, which is a chain reaction, acting on the membrane lipids with an initiation, propagation, and termination phase.…”
