Abstract

Objective:To establish the quality standard of Kangjun Xiaoyan Capsule.Method:The identification of Radix stemonae and Radix et rhizome rhei were carried out by TLC.The content of baicalin was determined by HPLC.Result: The TLC spots were clear and separated well without interference of negative sample.The calibration curve of baicalin was linear in the range of 0.01-0.16 g·L-1,Y=43 887 599.5X-4 893.8(r=0.999 9).The average recovery was 98.56% with RSD 1.01%(n=6).Condusion: The method is simple,rapid and accurate.It can be used for the quality control of Kangjun Xiaoyan Capsule.
