摘 要:目的:建立葛根芩连合剂中葛根素的HPLC含量测定方法。方法:色谱柱:ZORBAX Eclipse XDB C18(4.6mm×150mm,5μm),流动相:甲醇-0.2%醋酸水溶液(25:75),流速:1.0mL·min^-1,检测波长:250nm,进样量:5μL,柱温:25℃。结果:葛根素的回归方程为Y=4214.2x+83.295(r=0.9999),在42.08—420.8ng范围内线性关系良好;平均加样回收率为97.36%。(n=6),RSD为2.7%。结论:本方法简便可靠,重现性好,可用于葛根芩连合剂的质量控制。Objective:To establish a method for content determination of Puerarin in Gegen Qinlian Mixture by HPLC. Methods :The samples were determined by RP- HPLC on a ZORBAX Eclipse XDB C18 (4.6 mm× 150 mm,5 μm). The mobile phase consisted of methanol and 0.2% (v/v) acetic acid (25 : 75 ) ;the flow velocity was 1.0 mL · min ^-1 and the detection wavelength was at 250 nm;sample introduction was 5 txL and column temperature was controlled at 25 ℃. Results : The linear range of Puerarin was 42.08 - 420.8 ng and the regression equation was y = 4214.2x + 83. 295 ( r = 0. 9999). The average recovery rate was 97.36% with RSD as 2.7%. Conclusions : The method was simple and reliable, which can be used for the quality control of Gegen Qinlian Mixture.
