目的 :建立肝泰胶囊中的五味子甲素的含量测定方法。方法 :采用反相高效液相色谱法进行分离测定。 C1 8为固定相 ,甲醇-水 ( 75∶ 2 5 )为流动相 ,检测波长 2 5 0 nm。结果 :加样回收率为 1 0 0 .5 6 % ,RSD为 1 .0 2 % ( n=6 ) ;3批样品五味子甲素含量分别为 0 .1 2 % ,0 .1 1 % ,0 .1 1 %。结论 :此方法快速、简便 ,可作为该药质量控制方法。
Objective : To establish a method for determination of schizandrin A in Gantai Capsule. Methods : Separation and determination by reversed phase high performance liquid chromatography. C1 8 is the stationary phase, methanol-water (75:25) is the mobile phase, and the detection wavelength is 250 nm. RESULTS: The recovery rate of the sample added was 10.06% and the RSD was 1.02% ( n=6 ). The content of schisandrin A in the three batches of samples was 0.12%, 0.11%, 0 respectively. .1 1 %. Conclusion: This method is rapid and simple and can be used as a quality control method for this drug.
