Abstract

The bioactive ethyl acetate and N-butanol soluble parts of an ethanolic extract of Byrsocarpus coccineus check for this species in other resources leaves was subjected to column chromatography over silica gel G (60 - 120μ) and repeated purification of the flavonoid rich fraction over sephadex LH-20 eluted with methanol led to the isolation of three flavonoid glycosides identified as quercetin 3-O-α-arabinoside (I), quercetin(II) and quercetin 3-β-D-glucoside. Their structures were elucidated by 1H and 13C-NMR data and are reported here for the first time in this plant.
