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

ABSTRACT

OBJECTIVE: To investigate the chemical constituents of Ilex pernyi. METHOD: The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data. RESULT: 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). CONCLUSION: The eight compounds were obtained from this plant for the first time.
