肺热清解口服液质量标准研究

Study on Quality Standard of Feireqingjie Oral Liquid

目的研究肺热清解口服液的质量控制方法。方法采用紫外分光光度法测定肺热清解口服液中总黄酮的含量,采用薄层色谱法对肺热清解口服液中桑白皮进行定性鉴别,采用纸色谱法对肺热清解口服液中的地龙进行定性鉴别。结果总黄酮的浓度在0.00526～0.05260 mg/mL范围内与吸光度呈良好的线性关系(r=0.9998),平均回收率为98.65%,RSD=0.28%(n=6)。桑白皮的薄层色谱在与对照药材色谱相应位置上显相同的斑点,地龙的纸色谱在与氨基酸对照品和地龙对照药材的纸色谱相应位置上显相同的颜色,阴性对照均无干扰。结论本方法简便、准确,可作为控制肺热清解口服液质量的方法之一。

Objective To study the quality control method of Feireqingjie Oral Liquid. Methods UV was used to determine the content of total flavonoid. Cortex Mori was identified qualitatively by TLC. Pheretima was identified qualitatively by PC. Results Total flavonoid showed a good linear relationship in the range of 0.005 26-0.052 60 mg/mL, r=0.999 8. The average recovery rate was 98.65%, RSD=0.28% （n=6）. The TLC spot of Cortex Mori was coincident with the standard reference, and Pheretima showed the same color as the reference in PC, with no interference of negative control. Conclusion The method is convenient, accurate and can be used as one of the quality control methods of Feireqingiie Oral Liquid.
