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.
