[Studies on triterpenoid constituents in leaf of Ilex pernyi].

To investigate the chemical constituents of Ilex pernyi. The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data. Eight triterpenoid compounds were isolated and identified as ursolic acid (1), lupeol (2), alpha-amyrin (3), uvaol (4), 3beta-hydroxyurs-11-ene-13beta-olide (5), pomolic acid (6), lup-20 (29)-ene-3beta, 24-diol (7), 3beta, 23-dihydroxy-urs-12-en-28-oic acid (8). The eight compounds were obtained from this plant for the first time.
