摘　　要：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.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.
