Abstract

Objective To formulate the quality standard of Rukang Capsule. Method The TLC of Zhebeimu, Xuanshen, Ruxiang and Tiandong were done separately. The HPLC-ELSD was used to determine the content of Astragaloside in Mongolian Milkretch Root. Result There were the same spots between the controls and samples and an excellent linear relationship for 1.44～4.32 μg to the content determination of Astragaloside. The average recovery can reach 100.3% with 0.5% of RSD. Conclusion This method is reliable and accurate to application, and can be used for the quality control of the preperation.
