[Triterpenoids from leaves of Ilex cornuta].
OBJECTIVE
To investigate the chemical constituents of Ilex cornuta.


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


RESULTS
Seven compounds were isolated and identified as follows: 2alpha-hydroxy ursolic acid (1), arjunolic acid (2), 23-hydroxy ursolic acid (3), 27-0-p-(Z) -coumaroyl ursolic acid (4), 27-O-p-(E)-coumaroyl ursolic acid (5), asiatic acid (6).


CONCLUSIONS
Compound 1, 2 were obtained from this genus for the first time and 3-6 from this plant for the first time.
