Article Abstract

Four new flavonol glycosides, 5, 7, 5'-trihydroxy-3', 4'-dimethoxyflavonol-3---L-rhamnopyranosyl-(1→6)--D-glucopyranoside (), quercetin 3--(6--feruloyl)--D-glucopyranosyl-(1→2)--L-rhamnopyranoside (), kaempferol 3--(6--caffeoyl)--D-glucopyranosyl-(1→2)--L-rhamnopyranoside (), myricetin 3--(6---coumaroyl)--D-glucopyranosyl-(1→2)--L-rhamnopyranoside (), together with nine known flavonoids and two known lignans, were isolated from the leaves of . Their structures were determined by extensive spectroscopic analyses. Their cardioprotective effects against HO-induced apoptosis in H9c2 cells were also evaluated. The flavonol glycosides had stronger activity than the acylated flavonol glycosides at the concentration of 50 µM.
