Quercetin 3-O-β-D-(6''-p-coumaroyl)glucopyranosyl(1-2)-α-L-rhamnopyranoside Usage And Synthesis

Uses

Quercetin 3-O-β-D-(6''-p-coumaroyl)glucopyranosyl(1→2)-α-L-rhamnopyranoside (Quercetin-3-O-[2-O-(6-O-p-hydroxyl-E-coumaroyl)-D-glucosyl]-(1→2)-L-rhamnoside) is one of the major antioxidants of Ginkgo biloba leaves[1].

Definition

ChEBI: Quercetin 3-O-alpha-L-[6'''-p-coumaroyl-beta-D-glucopyranosyl-(1->2)-rhamnopyranoside] is a quercetin O-glucoside that is quercetin substituted by a alpha-L-[6'''-p-coumaroyl-beta-D-glucopyranosyl-(1->2)-rhamnopyranosyl] residue at position 3 via a glycosidic linkage. Isolated from Ginkgo biloba, it exhibits antioxidant activity. It has a role as a metabolite and an antioxidant. It is a quercetin O-glucoside, a cinnamate ester and a disaccharide derivative. It is functionally related to a trans-4-coumaric acid.
