摘要: 通过正交试验选择杜仲叶中绿原酸的最佳提取条件:30%甲醇回流20min,用反相液相色谱法测定绿原酸含量:色谱柱为KromasilC18柱,流动相为甲醇-0.02%磷酸溶液(体积比22:78),波长327nm,流速1.0ml/min。绿原酸在9.68~242μg/ml呈良好线性关系,相关系数r为0.9999,本法快速、简单、准确、分离度好、回收率大于95.9%。

Abstract: The conditions for the extracting chlorogenic acid in the Eucommia Ulmoides Olive leaves were optimized by the orthogonal test as follows: continuous extraction by 30% methanol for 20 minutes; determined by RP-HPLC. The chlorogenic acid was seperated on kromasil C18 column, with CH3OH~0.02%H3PO4 (22:78) at a flow-rate of 1.0ml/min and detected at UV 327nm.The calibration curve was linear in the range of 9.68~242μg/ml (r=0.9999). This method is simple, rapid and accurate with good separation, and the recoveries are above 95.9%.
