紫藤瘤化学成分研究

Chemical constituents of Wisteria Sinensis Sweet Caulis

目的研究紫藤瘤(Wisteria sinensis Sweet Caulis)化学成分。方法紫藤瘤(15 kg)95%乙醇渗漉液的石油醚萃取部位,经过硅胶、Sephadex LH-20等多种材料进行分离纯化,通过波谱技术进行结构鉴定。结果从95%乙醇提取物的石油醚萃取部位中分离鉴定了6个化合物,分别为蒲公英赛醇(1),蒲公英赛酮(2),木栓酮(3),表木栓醇(4),β-谷甾醇(5),β-胡萝卜苷(6)。结论化合物1～6均为首次从该种中分得。

Objective To study the chemical constituents of Wisteria sinensis Sweet Caulis.Methods The petroleum ether section from 95% ethanol extraction of Wisteria sinensis Sweet Caulis were separated and purified by silica gel,Sephadex LH-20 column chromatogra-phy,respectively.Their structures were elucidated by using spectroscopic analysis.Results Six compounds were isolated from the petroleum ether section of 95% ethanol extraction of Wisteria sinensis Sweet Caulis.They were identified as taraxerol（1）,Taraxerone（2）,Friedelin（3）,epifriedelanol（4）,β-sitosterol（5）,and β-daucosterol（6）.Conclusion Compounds 1~6 have been isolated from the plant for the first time.
