OBJECTIVETo investigate the chemical constituents of Ilex cornuta.

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

RESULTSeven 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).

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

OBJECTIVETo investigate the chemical constituents of the aerial parts of Polygala sibirica systematically.

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

RESULTTen compounds were isolated and identified as 6-hydroxy-1, 2, 3, 7-tetramethoxy xanthone (1); 1, 2, 3, 6, 7-heptamethoxy xanthone (2); 1, 7-didydroxy-2, 3-methylenedioxy xanthone (3); 1, 7-dihydroxy-2, 3-dimethoxy xanthone (4); 1, 3, 7-trihydroxy-2-methoxy xanthone (5); 1, 6, 7-trihydroxy-2, 3-dimethoxy xanthone (6); alpha-spinasterol (7); alpha-spinasterolic-3-O-beta-D-glucoside (8); squalene (9) and polygital (10).

CONCLUSIONCompounds 1-10 were isolated from this species for the first time.
