壮药青藤仔化学成分研究

Chemical Constituents from a Zhuang Medicine of Jasminum nervosum Lour.

采用硅胶、凝胶等柱色谱方法从壮药青藤仔Jasminum nervosum Lour.的茎中分离得到10个化合物,分别为β-谷甾醇(1)、豆甾醇(2)、β-胡萝卜苷(3)、齐墩果酸(4)、3-乙酰基齐墩果酸(5)、蒲公英赛醇(6)、白桦脂酸(7)、蒲公英赛酮(8)、豆甾醇-3-O-β-D-葡萄糖苷(9)、2α-羟基齐墩果酸(10)。其中化合物5-8和10为首次从该属植物中分离得到。

Ten compounds were isolated from a Zhuang medicine of Jasmznum nervosurn Lour. l ney were identified by physieochemical properties and spectral analyses as β-sitosterol（1）, stigmasterol （2）, β- daueosterol（3）, oleanolie acid（ 4）, acetyloleanolic acid （ 5 ）, astaraxerol （ 6 ）, betulinic acid （ 7）, taraxerone （8）, stigmasterol-3-O-β-D-glucopy-ranoside （9）, 2α-hydroxy-oleanolic acid （10）. Compounds 5-8 and 10 were isolated from this plant for the first time.
