目的为制定小儿感冒茶(山银花、板蓝根、重楼)的质量控制方法。方法用TCL鉴别山银花、板蓝根、重楼。用高效液相色谱法测定小儿感冒茶中绿原酸的含量。结果通过方法学考察,绿原酸检测浓度在0.244~1.952μg范围内与峰面积积分值呈良好的线性关系,加样回收率为99.22%,RSD%=0.92(n=2)。结论实验应用方法简便准确、重现性好、精密度高。所建质量标准可用于小儿感冒茶的质量控制。
The purpose of the development of pediatric cold tea (Shan Yinhua, Radix, re-floor) quality control methods. Methods TCL identification Shannon, Radix, re-floor. Determination of Chlorogenic Acid in Pediatric Cold Tea by High Performance Liquid Chromatography. Results By methodological study, the concentration of chlorogenic acid in the range of 0.244 ~ 1.952μg showed a good linear relationship with the peak area integral. The recovery rate was 99.22%, RSD% = 0.92 (n = 2). Conclusion Experimental method is simple and accurate, reproducible, high precision. The quality standards can be used for the quality control of pediatric cold tea.
