Abstract

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