摘要
建立祛屑息风胶囊的质量控制方法。色谱柱:Agilent TC-C_(18)(5μm,4.6 mm×250 mm);流动相:水-乙腈(40∶60);检测波长:322 nm;流速:1.0mL/min;柱温:25℃。蛇床子素进样量在0.089 0~0.9771μg与色谱峰面积呈良好的线性关系,平均回收率99.82%,RSD为0.93%。本研究建立的祛屑息风胶囊质量控制方法简单、结果稳定、重复性良好。
The quality control method of Quxiexifeng capsules was established.Chromatographic column:Agilent TC-C_(18)(5μm,4.6 mm×250 mm);water-acetonitrile(40∶60) as mobile phase;detection wavelength was322 nm;flow rate was 1.0 mL/min;column temperature was 25 ℃.In the range of 0.089 0-0.977 1μg of osthol,there was a good linear relationship between the injection volume and the peak area of chromatogram,with an average recovery of 99.82% and RSD of 0.93%.The quality control method of Quxiexifeng capsule established in this study is simple,stable and reproducible.
