藤黄中三萜成分的研究

Triterpenes from Garcinia hanburyi Hook.f.

采用正相、反相硅胶柱色谱法和半制备型高效液相色谱法对中药藤黄（Garcinia hanburyi Hook．f）中的三萜类化合物进行了分离和纯化，通过NMR谱鉴定共得到10个化学成分：白桦脂酸（1）、α-香树精（2）、羽扇豆醇（3）、β-香树素（4）、麦珠子酸（5）、蒲公英甾醇（6）、鲍尔烯醇（7）、丁酰鲸鱼醇（8）、3-O-α-L-吡喃阿拉伯糖齐墩果酸（9）和山楂酸（10）。其中，化合物3和4为首次从该植物中得到，化合物5—10为首次从该属植物中分离得到。

Ten triterpenes were isolated from Garcinia hanburyi Hook. f. by silica gel, reversed-phase silica gel column chromatography and semi-preparative high performance liquid chromatography. They were identified as betulinic acid （1）, α-amyrin （2）, lupeol （3）, β-amyrin （4）, alphitolic acid （5）, taraxasterol （6）, bauerenol （7）, butyrospermol （8）, 3-O-α-L-arabinopyranosyl oleanolic acid （9） and maslinic acid （ 10）. Compounds 3 and 4 were isolated from this plant for the first time, and compounds 5-10 were isolated from this genus for the first time.
