New Triterpene Saponins and Flavonol Glycosides from the Leaves of Ilex cornuta

Abstract A new triterpene glycoside, pomolic acid 3‐O‐6"‐methyl‐β‐D‐glucuronopyranosyl‐(1→3)‐α‐L‐arabino‐pyranoside, and a new flavonol glycoside, quercetin 3‐O‐β‐D‐glucopyranosyl‐(1→2)‐α‐L‐arabinopyranoside together with three known triterpene saponins and two flavonol glycosides, were isolated from the leaves of Ilex cornuta. Their structures were established on the basis of spectroscopic analysis.
