摘 要 ：目的：研究双籽藤黄Garcinia tetralata茎皮的化学成分。方法：采用硅胶、ODS柱色谱等方法进行分离纯化，根据理化性质及波谱数据鉴定化合物的结构。结果：从双籽藤黄95%乙醇提取物的氯仿萃取层中分离得到10个化合物，分别鉴定为1,7-二羟基酮(1)，buchanaxanthone(2)，garciniaxanthone H(3)，1,2,5-三羟基酮(4)，subelliptenone H(5)，6-deoxyisojacreubin(6)，6-deoxyjacreubin(7)，subelliptenone G(8)，苔色酸甲酯(9)和β-谷甾醇(10)。结论：化合物1～10均为首次从该种植物中分离得到，化合物9为首次从该属植物中分离得到。

Abstract:Objective: To study the chemical constituents of the barks of Garcinia tetralata. Method: Compounds were isolated and purified repeatedly by silica gel and ODS column chromatography and their chemical structures were elucidated by their physicochemical properties and spectral data analysis. Result: Ten compounds were obtained and identified as 1, 7-dihydroxyxanthone (1), buchanaxanthone (2), garciniaxanthone H (3), 1, 2, 5-trihydroxyxanthone (4), subelliptenone H (5), 6-desoxyjacareubin (6), 6-deoxyisojacreubin (7), subelliptenone G (8), methyl orsellinate (9) and β-sitosterol (10). Conclusion: Compounds 1-10 were isolated from this plant and compound 9 was obtained from the genus Garcinia for the first time.
