Flavonol glycosides from the leaves fissistigma pallens (FIN.GAGN.) merr.

Abstract

Using combined chromatographic methods, five flavonol glycosides including: kaempferol 3-rutinoside (1), rutin (2), kaempferol 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-galactopyranoside (3), isorhamnetin 3-robinobioside (4), and kaempferol 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranoside (5) were isolated from the methanol extract of the leaves of Fissistigma pallens (Fin. & Gagn.) Merr. Their chemical structures were determined using NMR spectra as well as in comparison with the reported data. All compounds were reported from Fissistigma genus for the first time.
