摘 要:目的:建立HPLC同时测定老鹳草属5种老鹳草中原儿茶酸、没食子酸、柯里拉京、鞣花酸和金丝桃苷含量的方法。方法:采用Agilent TC-C18色谱柱(4.6 mm×250 mm,5μm),流动相0.1%磷酸-乙腈梯度洗脱,流速1.0 m L·min-1,检测波长280 nm,柱温30℃。结果:原儿茶酸、没食子酸、柯里拉京、鞣花酸和金丝桃苷5种成分的线性范围分别为0.500~5.000μg(r=0.999 5),0.075~0.750μg(r=0.999 7),1.790~17.900μg(r=0.999 9),0.580~5.800μg(r=0.999 6),0.065~0.650μg(r=0.999 6),平均回收率在94.05%~102.58%,RSD在1.6%~2.9%。结论:该方法简单、准确,具有良好的重复性和稳定性,可为老鹳草药材的质量评价提供一定的参考依据。Objective: To establish an HPLC method to determine the content of protocatechuic acid,gallic acid, corilagin,ellagic acid and hyperoside in Geranii Herba. Method: HPLC column Agilent TC-C18( 4. 6 mm × 250 mm,5 μm) was eluted with the,mobile phase of 0. 1% phosphonic acid-acctonitril in a gradient mode,the flow rate was 1. 0 m L·min- 1,the detection wave-length was 280 nm,and the temperature was 30 ℃.Result: The linear ranges of the 5 ingredients in HPLC were 0. 500-5. 000 μg( r = 0. 999 5),0. 075-0. 750 μg( r = 0. 999 7),1. 790-17. 900 μg( r = 0. 999 9),0. 580-5. 800 μg( r = 0. 999 6),0. 065-0. 650 μg( r =0. 999 6),the ranges of average recoveries and RSD were 94. 05%-102. 58% and 1. 6%-2. 9%. Conclusion:The method is simple and accurate with a high repeatability,which could provide reference for the quality evaluation of Geranii Herba.
