摘要
目的:建立生脉颗粒中五味子醇甲的含量测定方法。方法:用高效液相色谱法测定,选用C18色谱柱(5μm,4.6mm×250 mm),流动相:甲醇-水(60:40),流速:1.0 mL/min,检测波长:250 nm。结果:五味子醇甲在0.05~0.2μg范围内线性关系良好,r=0.999 9,平均回收率为95.87%(n=6),RSD为0.39%。结论:该方法简便、灵敏、准确、重现性好,可作为生脉颗粒中五味子醇甲的含量测定方法。
Objective:To develop a method for determining the Schisandrin in shengmai granule. Methods: HPLC with ODS-C18 (5 μm ,4.6 mm x 250 mm) column was used. The mobile phase of Sehisandrin was a mixture of methanol H20 (60: 40) , with the flow rate of 1.0 ml/min and detection wavelength at 250 nm. Results: Schisandrin (0.05 -0.2μ g) showed fine linear relationship (r = O, 999 9) ,the average recovery was 95, 87% (n = 6) , RSD = 0.39%. Conclusion. The method is quick,simple and accurate and can be used to determine the content of Schisandrin in shengmai granule.
