Active component determination of Epimedium koreanum from different growing areas of Liaoning Province

采用HPLC法测定辽宁4个产区朝鲜淫羊藿不同部位中淫羊藿苷的含量,采用紫外分光光度法测定总黄酮的含量,以确定最佳产区。结果表明:朝鲜淫羊藿不同地区的有效成分含量不同,不同药用部位的总黄酮和淫羊藿苷含量差异较大,辽宁朝鲜淫羊藿的最佳产区是宽甸地区。

To determine the best production place of Epimedium koreanum through the the study of active component in Epimedium koreanum of four different place of production and different pharmaceutical genetic in Liaoning Province.
