摘要
目的:建立用高效液相色谱法测定小儿清热宁颗粒中黄芩苷的含量。方法:用DiamonsilTMC18柱;流动相为甲醇-水-磷酸(47∶53∶0.2);紫外检测波长280nm;柱温35℃。结果:黄芩苷的线性范围为0.06668-0.60012μg(r=0.9999),平均回收率为97.02%,RSD=1.28%(n=5)。结论:方法简单、准确、复方制剂中其他成分对测定无干扰,可用于该制剂的质量控制。
Objective:To develop a quantitative method by HPLC for the content determination of Baicalin in Xiaoerqingrening Granule. Method:The analysis was carried out using C-18 column (200mm ×4.6mm, 5μm). The mobile phase consisted of methanol-water-phosphoric acid (47: 53:0. 2,v/v). The detective wavelength was at 280nm. t =35℃. Results. The linear range of Baiealin was 0. 06668% 0. 60012μg (r = 0. 9999). The average recovery was 97. 02 % (RSD = 1.28%, n =5). Conclusion.The method was proved to be simple and accurate. It could be used in the quality control of Xiaoerqingrening Granule.
