Flavonol Glycosides from Parthenocissus tricuspidata Leaves

For the investigation of medicinal resources the studies were carried out to evaluate the pharmaco-constituents in the Leaves of Parthenocissus tricuspidata(Vitaceae), of which leaves have been used in Korea as folk remedies for the treatments of arthritis, jaundice, toothache, neuralgia, and etc. From 1-butanol fraction of the McOH extract, Compound I (C21Hl8O13. Quercetin-3-O-beta-D-glucuronopyranoside), Compound II (C2IH20O12, Quercetin-3-O-beta-D-glucopyranoside) and Compound III (C25H28O12, Quercetin-3-O-(6"-n-butyl)-beta-D-glucuronopyranoside) were isolated by column chromatographic separation using Sephadex LH-20 and ODS gel. Their structures were elucidated through instrumental analyses, such as 1H-NMR, 13C-NMR, IR, UV, EI-Mass, FAB-Mass and GC. Especially compound III was Flavonol glycoside and named parthenosin.
