摘要
目的 建立用高效液相色谱法测定复方百部止咳冲剂中黄芩苷含量的方法。方法色谱柱为Shim-Pack VPODS;流动为甲醇-水-乙腈(47:53:0.5);流速1.0mL/min;检测波长278nm;柱温(40.0±2)℃。结果 黄芩苷进样量在0.25~1.25μg范围内有良好的线性关系,回归方程为Y=3.262×10^6X+1.956×10^5,r=0.9998(n=5),平均回收率为99.42%,RSD=0.7%(n=5)。结论 该检测方法简便准确,可用于复方百部止咳冲剂的质量控制。
Objective To establish a method for determination of Baicalin in Co. Baibu Antitussive Granules by HPLC. Methods The column Diamomul C18 was used, the mobile phase consisted of methamol, water and acetonitrile (47: 53: 0.5), flow rate was 1.0 ml/min, the wavelength was at 278 nm. Results The linear range was within 0.25 to 1.25 μg, the average recovery was 99.42%, and RSD was 0.7% ( n = 5 ). Conclusion This assay method was simple and accurate.
