摘　　要：目的:建立5种藏五加菜中绿原酸的HPLC含量测定方法并比较其绿原酸的含量差异。方法:Kromasil C18柱(4.6 mm×250 mm,5μm),柱温30℃,流动相为乙腈(A)-0.2%磷酸水溶液(B)(10∶90);检测波长324 nm,流速1 mL.min-1。结果:70%甲醇回流提取100 min绿原酸的提取最完全,绿原酸在0.27～3.24 mg峰面积与进样量具有良好的线性关系,回归方程Y=3×106X-1.786 19×105,平均回收率100.25%,RSD 0.96%(n=9)。川产五加属植物中绿原酸含量老叶远低于嫩叶;不同种的川产五加属嫩叶绿原酸含量:糙叶藤五加嫩叶低温烘干品>蜀五加嫩叶低温烘干品>红毛五加嫩叶低温烘干品>无梗五加嫩叶低温烘干品;不同加工工艺中绿原酸的含量:茶叶>烘干>阴干≈热烫>晒干>微波干燥>>盐渍≈冻藏1个月。结论:方法简便、准确、重复性好,有助于藏五加菜质量控制方法的研究。Objective： To establish a RP-HPLC method to determine the content of chlorogenic acid from Tibetan vegetables of Acanthopanax. Method： The analysis was carried out at 30 ℃ on a Kromasil C18 column eluted with a mobile phase consisted of acetonitrile （A） -water with 0.2% phosphoric acid （B） （10： 90）. The detective wavelength was at 324 nm with the flow rate of 1.0 mL · min^-1. Result： The calibration curve of chlorogenic acid was linear within the concentration ranges of 0.27-3.24 mg with r of 0. 999 9 （ n = 7）. The average recovery was 100. 31% with RSD of 0.95% （n = 9）. Refluent extracting 100 m in with 70% methanol is the best way to acquire chlorogenic acid. The results of content of chlorogenic acid were as following： tender leave＇s 〉 eider leave＇s; tender leave＇s of A. leucorrhizus 〉A. setchuenensis 〉A. giraldii 〉A. sessiliforus. Tea made 〉 dried with electrothermal oven under 40 ℃ 〉 Shade-dried or equal to water-scalded with by boiling water in 2-5 min 〉 dried in the sun 〉 microwave-dried 〉 〉 pickled or equal to that of frozen. Conclusion ： This method was simple, accurate and repeatable. It was useful for the study of the quality control of TibetanVegetables of Acartthopanax.
