中药茅莓根、茎、叶中表儿茶素的含量测定

The Determination of the Content of L-epicatechin of Roots,Stems and Leaves from Rubus parvifolius L.

目的:比较中药茅莓不同部位中表儿茶素的含量,为临床用药提供参考。方法:采用HPLC法测定茅莓根、茎、叶中表儿茶素的含量,从化学成分上考察茅莓不同药用部位有效成分的分布。结果:不同产地茅莓根、茎、叶中表儿茶素含量有一定差异,以广西产地的含量稍高;茅莓根、茎、叶等部位均含有表儿茶素,三者含量有明显差异,含量的大小顺序依次为:叶>根>茎。结论:茅莓根、茎、叶中表儿茶素含量有显著差异,临床上作为药用应有所区别。

Objective：To compare the content of L-epicatechin from different parts of Rubus parvifolius L,to provide reference for clinical application.Methods：Using the method of HPLC to determine the content of L-epicatechin from roots,stems and leaves of Rubus parvifolius L.,to evaluate similarities and differences of Clinical efficacy on the chemical composition.Results：There was some different of the content of L-epicatechin for different place of Rubus parvifolius L.,and the content of Rubus parvifolius L.from Guangxi was lightly higher,we found the compound of L-epicatechin from roots,stems and leaves of Rubus parvifolius L.,and there are significant differences in the content of the three,the size of the order was：leaf root stem.Conclusion：There was some different of the content of L-epicatechin for roots,stems and leaves of Rubus parvifolius L.,it should be different as a medicinal clinic.
