Objective : To establish a method for the determination of the content of Qingshang Qutong Capsule. Methods: The wavelength of λR was measured at 370nm by thin-layer scanning method. The developing solution was chloroform-methanol-water (80∶35∶10) submerged overnight at 10°C, and ultraviolet light (365nm) was positioned. RESULTS: The average recovery of puerarin was 98 43% and the RSD was 145 %. Conclusion: This method is simple, accurate and reliable. It can be used as one of the quality control indicators of the preparation.
