摘 要:目的通过HPLC法测定银黄胶囊中绿原酸和黄芩苷的含量。方法以《中国药典》2015年版一部为依据,采用HPLC法,色谱柱为C18反相液相色谱柱,流动相:乙腈-0.4%磷酸(13:87)和甲醇-水-磷酸(47:53:0.2);检测波长:327nm和280nm;流速:1.0ml/min;柱温:25℃。结果该方法样品处理简单、分离度良好,具有良好的重现性。结论本方法可以确保产品质量,可以作为银黄胶囊的质量标准检测方法。Objective To determine the content of chlorogenic acid and baicalin in Yinhuang capsules by HPLC. Method HPLC was used with C18 column. Flow phase: acetonitrile -0.4% phosphoric acid (13:87) and methanol - water - phosphoric acid (47:53:0.2); detection wavelength: 327 nm and 280 nm; flow rate: 1.0 ml/ min; column temperature: 25℃. Result The sample was easy to deal with and the chromatogram was good with a good reproducibility. Conclusion The method can be used to control the quality of Yinhuang capsules.
