摘    要:目的建立同时测定双黄连冻干粉中黄芩苷和连翘苷含量的高效液相色谱法。方法采用Hypersil-C18柱(250mm×4,6mm,5μm),流动相为甲醇-乙腈-水-磷酸(65:15:75:0,5),流速为1.0mL/min,检测波长为230nm。结果黄芩苷进样量在0,14-2,80μg范围内与峰面积线性关系良好(r=0.9998),平均回收率为98,09%,RSD=0,76%(n=6);连翘苷进样量在0,077-1.93μg范围内与峰面积线性关系良好(r=0,9997),平均回收率为98,38%,RSD=1,11%(n=6)。结论方法专属性强、准确、快速,适用于双黄连冻干粉的质量控制。

关 键 词:高效液相色谱法  黄芩苷  连翘苷  含量测定

Abstract:Objective To establish a HPLC method for the determination of baicalin and phillyrin in Shuanghuanglian Powder. Methods The column was Hypersil ODS (250 mm × 4.6 mm, 5 μm). The mobile phase consisted of methanol - acetonitrile - water - phosphoric (65 : 15 : 75:0. 5). A gradient method was set up. The flow rate was 1.0 mL/min. The detecting wavelength was at 230 nm. Results The calibration curves were linear in the range of 0. 14-2. 80 μg for baicalin(r = 0. 999 7),and 0. 077- 1.93μg for phillyrin,respectively. The average recovery rates were 98. 09% and 98.38% (n =6) with RSD of 0.76% and 1.11% ,respectively, Conclusion The method is rapid and accurate. It can be used for quality control of Shuanghuanglian Powder.
Keywords:HPLC  baicalin  phillyrin  content determination
