摘要
目的 :测定不同采收月份老鹳草生药 (ErodiumstephanianumWilld .)中柯里拉京 (corilagin)的含量 ,确定最佳采收时间。方法 :采用高效液相色谱法对不同采收月份的老鹳草生药中柯里拉京进行含量测定。结果 :柯里拉京在 0 .2 2～1 .1 0 μg范围内呈良好的线性关系 ,平均回收率为 98.6 %(RSD为 0 .6 3%)。 结论 :8月份采收的老鹳草生药中柯里拉京含量最高。
AIM: To determine the contents of corilagin in Erodium stephanianum Willd. from different collection month and to define the best collection time for this herb. METHODS: The contents of corilagin in each samples of E. stephanianum were determined by HPLC. RESULTS: The linear regression of corilagin was obtained in the range of 0.22～1.10μg. The average recovery was 98.6% with a RSD of 0.63%. CONCLUSION: The content of corilagin in E. stephanianum collected in August is the highest among the samples throughout the collection months.
