Objective: To establish the quality standard for Zhang's Jinshu pills. Methods: Identification of Salvia miltiorrhiza,Angelicae Dahuricae Radix,and Astragalus membranaceus in Zhang's Jinshu pills was performed by thin- layer chromatography( TLC),and high- performance liquid chromatography was used to determine the content of puerarin in Radix Puerariae in this prescription. Results: TLC had a good specificity with no negative interference. Puerarin showed a good linear relationship between concentration and peak area withi0. 979μg( r = 0. 9997),and the average recovery rate was 97. 1%( n = 6). Conclusion: This method is simple and accurate and can be used for the quality control of Zhang's Jinshu pills.
