Polyphenolic compounds from Abutilon grandiflorum leaves

The flavonol glycosides: kaempferol 3-O-beta-(6"-p-coumaroyl)-glucopyranoside, kaempferol and quercetin 3-O-beta-glucopyranosides and 3-O-beta-rutinosides were isolated and identified from the leaves of Abutilon grandiflorum. Their structures were established by chemical and spectroscopic methods. The presence of phenolic acids: p-hydroxybenzoic, p-coumaric, syringic, and vanillic was confirmed by TLC.
