Constituintes químicos e atividade antioxidante de Byrsonima gardneriana (Malpighiaceae)

Abstract: Recebido em 11/7/12; aceito em 30/10/12; publicado na web em 28/2/13 CHEMICAL CONSTITUENTS AND ANTIOXIDANT ACTIVITY OF Byrsonima gardneriana (Malpighiaceae). The phytochemical investigation of Byrsonima gardneriana led to the isolation of five triterpenes and one flavonoid: D:B-Friedoolean-5-en-3-one (1), friedoolean-14-en-3-one (2), friedelan-3-one (3), lup-20(29)-en-3-ol (4), 3β-hydroxiolean-12-ene (5) and 3,3',4',5,7-pentahydroxyflavan (6). Their structures were assigned based on spectroscopic analyses, inc… Show more

“…These results point that the extract have antioxidant activity, justified by the presence of phenolic compounds and flavonoids, known by their capacity to redeem free radicals and inhibit possible oxidant damages. The same antioxidant activity of hidro ethanolic extract of Bysonima crassifolia leaves was previously described by (Pompeu et al, 2012) and for others species of the same genre by (Rolim et al, 2013).…”

“…Studying barks of B. crassifolia, Silva and Rogez (2013), found similar value to the one observed in this paper (208.1 ± 9.7 mg g-1) and superior to the one found by Pompeu et al (2012) that was 58.1 mg g -1 of total phenols for the hydroethanol crude extract of dried leaves of B. crassifolia collected at the region of Belem, PA, Brazil. For the crude extract of aerial parts of B. gardneriana, the values were superiors (425.105 ± 8.523 mg EAG g-1) (Rolim et al, 2013), which suggests that Byrsonima species have high levels of total phenols in their composition. Still, differences found in several studies with B. crassifolia, may be associated to the solvent and the extraction method used (Simões et al, 2010), just like geographic localization and environmental factors form the region where plants are collected may influence the presence and intensity of secondary metabolites (Gobbo-Neto and Lopes, 2007).…”

“…Approximately 90 species occur in Brazil, 35 of which are found in different areas of the northeastern region of the country, including the state of Pernambuco [2].The use of plants of this genus in northeastern Brazil is common in folk medicine for the treatment of fever, gastrointestinal problems (diarrhea and gastric ulcer), asthma, skin infections, and snake bites [3,4]. Byrsonima sericea DC., known locally as "murici," stands out among the species that occur in the state of Pernambuco with broad distribution in fragments of the Atlantic Rainforest [5].…”
