Objective To investigate the chemical constituents from the leaves of Ilex chinensis. Methods The constituents were isolated and purified by various chromatographic methods, and the structures were elucidated by spectroscopic analysis. Results Fifteen triterpenoid compounds were isolated from 70% ethanol extract in the leaves of I. chinensis and identified as 2α,3β-dihydroxy-23-norolean-4(24)-12(13)-dien-28-oic acid (1), 29-hydroxyhederagenin (2), ilexosapogenin A (3), rotundic acid isopropylidene (4), 2α,3β-dihydroxy-23-norurs-4(24)-12-dien-28-oic acid (5), 23-hydroxyursolic acid (6), 3β,23-dihydroxyursa-12,18-dien-28-oic acid (7), asiatic acid (8), 28-O-β-D-glucopyranoside siaresinolic acid (9), 28-O-β-D-glucopyranoside spathodic acid (10), 28-O-β-D-glucopyranoside pomolic acid (11), rotungenoside (12), 3β,23-dihydroxyurs-12,18-dien-28-O-β-D-glucopyranosyl ester (13), 3β,23-dihydroxyurs-12,19-dien-28-O-β-D-glucopyranosyl ester (14), and 3β,23-dihydroxyurs-12,19(29)-dien-28-O-β-D-glucopyranosyl ester (15). Conclusion Compounds 1 and 2 are isolated from the plants of Ilex L. for the first time. All compounds are isolated from this plant for the first time.
