HPLC法测定扶正化瘀片中五味子醇甲、乙含量

Determination of schisandrol A and B in Fuzheng Huayu tablets by HPLC

目的:建立HPLC法同时测定扶正化瘀片中五味子醇甲、乙含量的方法,为扶正化瘀片的质量标准提升提供参考依据。方法:采用Agilent Zorbax Extend C18柱对五味子醇甲和五味子醇乙进行HPLC分析,流动相为甲醇-水,梯度洗脱;流速1.0 mL/min;柱温30℃;检测波长250 nm。结果:五味子醇甲、乙质量浓度分别在0.0240~1.2034 mg/mL(r=0.9999)、0.0157~0.7845 mg/mL(r=0.9999)范围内线性关系良好,平均加样回收率分别为105.63%(RSD 0.90%、n=9)、103.24%(RSD 3.81%、n=9)。结论:该方法准确稳定,重复性好,适用于扶正化瘀片中五味子醇甲、乙的质量控制。

Objective:An HPLC method was established for the content determination of schisandrol A and B in Fuzheng Huayu tablets,so as to provide reference for the improvement of the quality standard.Methods:An HPLC for the determination of schisandrol A and B was performed on an Agilent Zorbax Extend C18 column with the mobile phase comprising of methanol-water flowing at 1.0 mL/min in a gradient elution manner at the detection wavelengths of 250 nm and column temperature of 30℃.Results:The schisandrol A and B showed a good linearity in the range of 0.0240-1.2034 mg/mL(r=0.9999)and 0.0157-0.7845 mg/mL(r=0.9999),respectively.The average recoveries were 105.63%(RSD 0.90%,n=9)for schisandrol A and 103.24%(RSD 3.81%,n=9)for schisandrol B.Conclusion:This method is accurate,stable and repeatable and is suitable for the quality control of schisandrol A and B in Fuzheng Huayu tablets.
