目的:研究清咽利喉片的质量控制标准。方法:采用薄层色谱法鉴别方中的厚朴和玄参,采用高效液相色谱法测定方中君药金银花主要有效成分绿原酸的含量。结果:薄层色谱分离清晰,阴性无干扰。定量方法简便、准确,绿原酸在0.198~1.98μg范围内呈良好的线性关系,平均回收率为99.65%,RSD为1.84%。结论:所建立方法专属性强,灵敏度高,重复性好,可用于清咽利喉片的质量控制。
Objective: To study the quality control standard of Qingyan Lie Liao Tablet. METHODS: Magnolia officinalis and Radix Scrophulariae were identified by TLC, and the content of chlorogenic acid in the main active ingredient of honeysuckle was assayed by high performance liquid chromatography. Results: TLC separation was clear and negative without interference. The quantitative method was simple and accurate. The linear relationship between chlorogenic acid and choline acid in the range of 0.198-1.98μg was obtained. The average recovery was 99.65% and the RSD was 1.84%. Conclusion: The established method has the advantages of high specificity, high sensitivity and good repeatability. It can be used for the quality control of Qingyan Lee Lage.
