Flavonols from the Leaves Lygodium Microphyllum (lygodiaceae)

Abstract

Flavonol compounds, quercetin (1) and quercetin-3-O-?-D-glucopyranoside (2) have been isolated from the ethyl acetate extract of Lygodium microphyllumleaves. The chemical structures of flavonol compounds were identified based on spectroscopic data and by comparison of spectral data obtained previously. The discovery of flavonol compounds in Lygodium microphyllumwas shown in this study for the first time.
