摘 要 ：目的：研究版纳藤黄Garcinia xipshuanbannaensis枝叶的化学成分。方法：利用正相硅胶、反相RP-18柱色谱及葡聚糖凝胶Sephadex LH-20等手段进行分离纯化，根据波谱数据鉴定化合物的结构。结果：分离鉴定了15个化合物，分别为bannaxanthone E(1)，大叶藤黄醇(xanthochymol，2)，异大叶藤黄醇(isoxanthochymol，3)，环大叶藤黄醇(cycloxanthochymol，4)，osajaxanthone(5)，gentisein(6)，mangostinone(7)，山柰酚(8)，槲皮素(9)，牡荆素(10)，2″-O-acetylvitexin(11)，3-乙酰齐墩果酸(12)，(-)-表儿茶素［(-)-epicatechin，13］，β-谷甾醇(14)，胡萝卜苷(15)。结论：化合物4～9，11～13为首次从该种植物分离得到，化合物11～13为首次从该属植物分离得到。

Abstract:Objective: To study the chemical constituents of the twigs of Garcinia xipshuanbannaensis. Method: The compounds were isolated by column chromatography with silica gel, RP-18 and Sephadex LH-20, and their structures were elucidated by spectroscopic analysis. Result: 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), β-sitosterol (14) and daucosterol (15), respectively. Conclusion: 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.
