接骨草叶石油醚部位化学成分

Chemical Constituents of Petroleum Ether Extract of Sambucus chinensis Leaves

目的：研究忍冬科植物接骨草Sambucus chinensis叶石油醚萃取部位的化学成分.方法：运用乙醇渗漉法对接骨草叶进行提取,对石油醚萃取部位采用多种色谱手段进行分离纯化,通过波谱解析进行结构鉴定.结果：从接骨草叶中分离得到8个化合物,分别为乌索酸（1）,齐墩果酸（2）,β-谷甾醇（3）,胡萝卜苷（4）,鲨烯（5）,植醇（6）,正二十五烷醇（7）,十七烷酸对羟基苯乙酯（8）.结论：化合物5-8为首次从该属植物中分离得到.

Objective：The chemical constituents of extract of petroleum ether soluble part from leaves of Sambucus chinensis were investigated.Method：After being extracted with ethanol percolation,the chemical constituents were isolated and purified by column chromatography and their structures were identified by spectral analysis.Result：Eight compounds were obtained from leaves of S.chinensis and identified as ursolic acid （1）,oleanic acid （2）,β-sitosterol （3）,daucosterol （4）,squalene （5）,phytol （6）,n-pentacosanol （7）,4-hydroxyphenethyl heptadecanoate （8）.Conclusion：Compounds 5-8 were isolated from genus Sambucu for the first time.
