Objective: To investigate the chemical constituents of Ilex cornuta.
Method: The chemical constituents were isolated by column chromatographic methods. And the structures were identified by spectral data.
Result: 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).
Conclusion: Compound 1, 2 were obtained from this genus for the first time and 3-6 from this plant for the first time.
