Abstract
Two novel acylated flavonol glycosides were isolated from the n-butanol fraction of the ethanolic extract of Platanus orientalis L. leaves. They were identified as kaempferol-3-O-(2″’-p-E-coumaroylrhamnosyl)(1″’→6″)-[β-D-glucopyranosyl-(1′″→2″)-β-D-glucopyranoside]-7-O-α-L-rhamnopyranoside, and quercetin-3-O-(2″’-p-E-coumaroylrhamnosyl)(1″’→6″)-[β-D-glucopyranosyl-(1″″→2″)-β-D-glucopyranoside]-7-O-α-L-rhamnopyranoside. Their structures were established on the basis of detailed spectral analysis.
