title: Rhamnetin 3-p-coumaroylrhamninoside from Rhamnus petiolaris.
abstract: From the berries of Rhamnus petiolaris a new acylated flavonol glycoside was isolated and identified as rhamnetin 3-O-[3""-O-(p-coumaroyl)-alpha-L-rhamnopyranosyl(1-->3)- alpha-L-rhamnopyranosyl(1-->6)]-beta-D-galactopyranoside. Additionally, five known flavonol glycosides, rhamnetin, rhamnazin, quercetin and kaempferol 3-rhamninosides, and quercetin 3-rhamnoside were isolated.
