Perfil de flavonoides e avaliação do potencial antioxidante e citotóxico de Bauhinia purpurea (Fabaceae) da região amazônica

Abstract: FLAVONOID PROFILES AND EVALUATION OF ANTIOXIDANT POTENTIAL AND CYTOTOXICITY OF AMAZONIANBauhinia purpurea (Fabaceae). Plants of the Bauhinia species (Fabaceae) are used in the treatment of several infections and diseases, especially diabetes. In this paper, with an aim to contribute to the knowledge of the chemistry and therapeutic potential of the Amazonian species of the genus Bauhinia, flavonoid profiles in the leaves and branches of Bauhinia purpurea collected in Manaus and São Gabriel da Cachoeira/AM were… Show more

“…Compounds 7 (luteolin-6-C-glucoside, homoorientin), 13 (quercetin-3-O-rutinoside, rutin), 14 (apigenin-6-C-glucoside, isovitexin), 15 (quercetin-3-O-glucoside, isoquercetin), 17 (kaempferol-3-O-rutinoside, nicotiflorine) and 18 (kaempferol-3-Oglucoside, astragalin) were all identified according to their retention time, mass and UV-vis characteristics by comparison with commercial standards. These compounds have also been reported in other Bauhinia species by some authors (dos Santos et al, 2014;Farag et al, 2015;Ferreres et al, 2012;Liu et al, 2016).…”

“…Os flavonóides representam um dos grupos fenólicos mais importante e diversificados de origem natural, sendo atribuído a diversos efeitos biológicos, como atividade antitumoral, antiviral, inibem a peroxidação de lipídeos e a agregação de plaquetas, ativa sistemas de enzimas, incluindo ciclooxigenases e hipoxigenases e esses efeitos são devidos a sua capacidade de remover radicais livres e de quelar cátions divaIentes. 20,21 Há relatos também da presença dos flavonóides em Bauhinia variegata L., sendo esta a principal classe de interesse para a possível atividade antioxidante dessa espécie. 22 Antioxidantes são agentes que retardam ou previnem as lesões causadas pelos radicais livres nas células, sendo qualquer substância que presente em baixas concentrações quando comparada ao substrato oxidável, atrasa ou inibe a oxidação deste substrato de maneira eficaz.…”
