利用HPLC测定诃子的两种传统藏药炮制品中多酚类成分含量的变化

摘要

Taking Terminalia chebula Retz.as the control product,the polyphenolic contents of the processed products in Tibetian,Rubia cordifolia L.processed Terminalia chebula Retz.and Euphorbia fischeriana Steud processed Terminalia chebula Retz.were analyzed by HPLC.Polyphenolic contents increased from 4.54％ to 5.69％ and 7.46％,respectively,which may lead to the change in their pharmacological effects.%本文以生药诃子为参考,采用HPLC法对诃子的两种藏医炮制品,茜草制诃子和白狼毒制诃子中多酚类成分的含量变化进行研究.结果显示,炮制后诃子中多酚类成分含量均有增加,其含量由4.54％分别增至5.69％和7.46％这可能导致了两种炮制品药理作用的改变.
