大果木姜子的化学成分

Study on Chemical Constituents of Cinnamomum migao

目的:研究大果木姜子Cinnamomum migao H.W.Li的化学成分。方法:采用多种色谱法分离纯化,通过光谱分析、理化常数测定及与文献、已知化合物对照进行结构确认。结果:从中分离得到6个化合物,其结构鉴定为(+)-儿茶素(1)、β-谷甾醇(2)、东莨菪内酯(3)、5,7,4’-三羟基二氢黄酮(4)、6,8-二甲氧基-7-氧-β-D-葡萄糖香豆素(5)、胡萝卜苷(6)。结论:所有化合物首次从该植物中分离得到,其中化合物3～6为首次从该属植物中分离得到。

Objective：To study the chemical constituents of Cinnamomum migao.Method：Various chromatographic techniques were employed for isolation and purification of the constituents.Their structures were identified by means of spectral analysis and comparison with the reported data.Result：Compounds isolated from C.migao were identified as（＋）-catechin（1）,β-sitosterol（2）,scopoletin（3）,5,7,4’-thihydroxyflavanone（4）,isofraxidin-β-D-glucosid（5）,daucosterol（6）.Conclusion：All compounds were isolated from C.migao for the first time,in which compounds（3-6） were firstly reported in this genus. 更多
