目的:建立测定五仁醇胶囊中的五味子乙素含量的HPLC法。方法:Kromasil ODS C_(18)柱(250 mm×4．6 mm,5μm),以乙腈-水(65:35)为流动相,流速1．0 ml·min~(-1);检测波长为254 nm。结果:五味子乙素在0．10-2．52μg范围内,线性关系良好(r=1．000 0),平均回收率为100．0％,RSD 1．1％(n=5)。结论:该方法可用于五仁醇胶囊的质量控制。
Objective: To establish HPLC method for determination of schizandrin B content in Wuren alcohol capsules. Method: Kromasil ODS C 18 column (250 mm×4.6 mm, 5 μm) with acetonitrile-water (65:35) as mobile phase, flow rate 1.0 ml·min -1, detection wavelength 254 nm. RESULTS: In the range of 0.10-2.52 μg, the schisandrin B had a good linear relationship (r=1.000 0). The average recovery was 100.0% and the RSD was 1.1% (n=5). Conclusion: This method can be used for the quality control of Wuren alcohol capsules.
