%X Eleven compounds were extracted from EtOH extract of the twigs of Calophyllum inophyllum. On the basis of spectroscopic data, their structures were identified as 6-hydroxy-2,3-dimethoxyxanthone ( 1 ) , 1,3,7-trihydroxylxanthone ( 2 ) , 1,3,7-trihydroxy-8-methoxyxanthone ( 3 ) , 7-hydroxy-1,3-dimethoxyxanthone ( 4 ) , pseudo taraxasterol ( 5 ) , 1,3,6-trihydroxy-5,7-dimethoxyxanthone ( 6 ) , 2-hydroxy-1-methoxy-xanthone ( 7 ) , 2-hydroxy-1,8-dimethoxyxanthone ( 8 ) , 1,3,5-trihydroxy-2-methoxyxanthone ( 9 ) , 4-hydroxyxanthone ( 10 ) , and 1,3,5-trihydroxyxanthone ( 11 ) . Compounds 6 - 8 were isolated from this plant for the first time, and compounds 2 - 5 from the genus Calophyllum for the first time. Compound 1 was a new natural product. Compound 9 showed inhibitory activities towards human gastric carcinoma (SGC-7901), with the IC50 value of 1.8×10-5 mol/L.
