摘要
目的建立测定复方思日颗粒中绿原酸含量的方法。方法采用Waters Sun Fire TMCis(150mm×4.6mm,5μm)色谱柱,流动相为甲醇(A)-乙腈(B)-0.4%磷酸水溶液(C),梯度洗脱(0~50min,5.5%A-6%A,2.9%B,91.6%C→91.1%C),柱温30℃,流速1.0mL/min,检测波长327nm,进样量15μL.结果绿原酸对照品在4.24~25.44μg/mL浓度范围内与峰面积的线性关系良好。加标回收率为98.739%(n=9),RSD为2.622%,分离度〉1.5,对称因子不得低于0.7。结论HPLC方法简便、结果准确,可用于复方思日颗粒中绿原酸的含量测定。
Objective To establish a HPLC method to determine the content of Chorogenic acid in Si Ri Granules. Method A Waters SunFire TM Cls (150 mm×4.6 mm, 5μm) column was used. The mobile phase was methanol(A)-acetonitrile(B)--0.4%H3PO4(C)(0~50 rain,5.5% A→6% A,2.9%B,91.6% C →91.1% C)with gradient elution and detection wavelength was 327 nm. The flow rate was 1.0 mL/min, the injection volume was 15 μL and the column temperature was 30℃. Result A good linearity was obtained in the range of 4.24~25.44μg/mL. The average recovery was 98.739%(RSD 2.622%, n =9). The Separating size was more than 1.5, the symmetrical factor was not less than 0.7. Conclusion The method was good for determining Chorogenic acid in Si Ri Granules.
