柿皮化学成分的研究

Chemical Constituents form Exocarp of Diospyros kaki

目的:研究柿皮Diospyros kaki的化学成分。方法:采用硅胶柱色谱方法分离纯化,通过1H-NMR,13C-NMR,MS,IR等波谱方法以及化合物的理化性质进行结构鉴定。结果:从柿皮中分离得到7个化合物,分别鉴定为棕榈酸(1),β-谷甾醇(2),乌苏酸(3),24-丙基-3β-羟基-胆甾-5-烯(4),齐墩果酸(5),东莨菪内酯(6),肉豆蔻酸(7)。结论:化合物4,6,7均首次从该植物中分离得到。

Objective：To study the chemical constituents from exocaep of Diospyros kaki.Method：Compounds were isolated by chromatographic techniques.The structures were identified by physicochemical properties and spectral analyses（1H-NMR,13 C-NMR,MS and IR）.Result：Seven compounds were isolated and identified as palmitic acid（1）,β-sitosterol（2）,ursolic acid（3）,24R-24-propylcholest-5-en-3β-ol（4）,oleanolic acid（5）,scopoletin（6）,myristic acid（7）.Conclusion：Compounds 4,6,7 were obtained from this plant for the first time.
