[Studies on triterpenoid constituents in leaf of Ilex pernyi].
OBJECTIVE
To investigate the chemical constituents of Ilex pernyi.


METHODS
The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.


RESULTS
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).


CONCLUSIONS
The eight compounds were obtained from this plant for the first time.
