摘要
目的 确立HPLC法测定慢性咽炎口服液中黄芩苷的含量。方法色谱柱:Agilent XDB—C18柱(150mm×4.6mm、5μm);流动相:甲醇-水-磷酸(47:53:0.2);流速:1.0mL·min^-1;检测波长:280nm。结果黄芩苷在0.05~0.24μg范围内呈良好的线性关系(r=0.9997),平均回收率99.9%,RSD1.0%。结论方法简单可行.可控制慢性咽炎口服液的质量。
Objective To establish the method for determine the content of baicalin in oral liquid for chronic pharyngitis. Methods Chromatographic column: Agilent column XDB - C18 ( 150mm× 4.6mm , 5μm ) ; mobile phase: methanol -water-phosphoric acid (47:53:0.2) ; flow rate:l.0mL· min^-1 ; wavelength: 280 nm. Results Baicalin had a good linear relationship between 0.05 - 0. 241μg, the average recovery rate was 99.9 %. Conclusion The method is simple and feasible, and can control the quality of oral liquid for chronic pharygitis
