山慈菇乙酸乙酯部位化学成分研究

Study on the Chemical Constituents from the Ethyl Acetate Extracts of Cremastra appendiculata

目的:研究山慈菇醇提物的乙酸乙酯部位的化学成分。方法:采用硅胶柱色谱和Sephadex LH-20柱色谱对山慈菇醇提物的乙酸乙酯部位进行分离纯化,根据理化性质和波谱数据分析鉴定化合物。结果:从山慈菇乙酸乙酯部位分离得到7个化合物,分别鉴定为:富马酸(1)、邻苯二甲酸二乙基己酯(2)、L-焦谷氨酸(3)、2-呋喃羧酸(4)、香草酸(5)、对香豆酸(6)、原儿茶酸(7)。结论:其中,化合物1～6为首次从该植物中分离得到。

Objective：To study the chemical constituents from the ethyl acetate extracts of Cremastra appendiculata.Methods：The compounds from the ethyl acetate extracts were isolated by the silica gel column and Sephadex LH-20 column chromatography,their structures were elucidated by the spectral analysis and chemical evidence.Results：Seven componds were separated and identified as fumaric acid（1）,dimethylhexyl phthalate（2）,L-pyroglutamic acid（3）,2-furoic acid（4）,vanillic acid（5）,p-coumaric acid（6）,protocatechuic acid（7）.Conclusions：Compounds 1 to 6 are obtained from this plant for the first time.
