To study the chemical constituents of the twigs of Garcinia xipshuanbannaensis. The compounds were isolated by column chromatography with silica gel, RP-18 and Sephadex LH-20, and their structures were elucidated by spectroscopic analysis. Fifteen compounds were obtained and identified, which were bannaxanthone E (1), xanthochymol (2), isoxanthochymol (3), cycloxanthochymol (4), osajaxanthone (5), gentisein (6), mangostinone (7), kaempferol (8), quercetin (9), vitexin (10), 2"-O-acetylvitexin (11), 3-acetoxyoleanolic acid (12), (-)-epicatechin (13), beta-sitosterol (14) and daucosterol (15), respectively. Compounds 4-9 and 11-13 were isolated from the plant and compounds 11-13 were obtained from the genus Garcinia for the first time.
