摘要
[目的]研究藤黄科藤黄属植物大叶藤黄(Garcinia xanthochymus)的化学成分。[方法]采用硅胶柱色谱、Sephadex LH-20、ODS以及MCI等多种色谱方法分离纯化,并根据理化性质和波谱数据鉴定化合物结构。[结果]从大叶藤黄提取中分离鉴定了10个化合物,经波谱解析分别鉴定为1,4,5,6-Tetrahydroxy-7,8-diprenylxanthone(1)、1,7-二羟基口山酮(2)、Isogarciniaxanthone E(3)、1,4,5,6-Tetrahydroxy-7-prenylxanthone(4)、Subelliptenone G(5)、1,4,6-Trihydroxy-5-methoxy-7-prenylxanthone(6)、Carpachromene(7)、6-Prenylapigenin(8)、达玛烯二醇II(9)、3-Epicabraleadiol(10)。[结论]该试验分离鉴定的化合物7、9、10为首次从该属植物中分离得到。
[ Objective ] The research aimed to study the chemical constituents of Garcinia xanthochymus. [ Method ] The extract of Garcinia xanthochymus was isolated and purified by silica gel, Sephadex LH-20, ODS and MCI gel. Their structures were elucidated on the basis of physicochemical properties and spectroscopic data. [ Result ] Ten compounds were identified as 1,4,5,6-Tetrahydroxy-7,8-diprenylxanthone （ 1 ）, 1,7-Dihydroxyxanthone （ 2 ）, Isogareiniaxanthone E （ 3 ）, 1,4,5,6-Tetrahydroxy-7-prenylxanthone （ 4 ）, Subelliptenone G （ 5 ）, 1,4,6- Trihydroxy-5-methoxy-7-prenylxanthone （6）, Carpachromene （7）, 6-Prenylapigenin （8）, Dammarenediol II（9） , 3-Epicabraleadiol （10）, respectively. [ Conclusion] Compounds 7, 9, 10 were isolated from the genus Garcinia for the first time.
