OBJECTIVE： To develop and improve the quality standard for Kanggu zengsheng tablet. METHODS： TLC was used for the qualitative identification of Drynaria fortunei， Epimedii Folium and Spatholobus suberectus； HPLC was used for the contents determination of icariin and acteoside： the column was Diamonsil C18 with mobile phase of acetonitrile-0.1％ formic acid solution （gradient elution） at a flow rate of 1.0 mL/min； detection wavelength was 270 nm for icariin and 334 nm for acteoside， Cdumn temperature was 25 ℃，and the injection volume was 10 μL. RESULTS： The TLC spots of D. fortunei， Epimedii Folium and S. suberectus were clear and well separated， negative control without interference. The linear range was 0.018 8-1.88 μg for acteoside （r＝0.999 9） and 0.107-2.14 μg for icariin （r＝0.999 9）； RSDs of precision， stability and reproducibility tests were lower than 2.0％；recoveries were 100.2％-105.0％（RSD＝1.6％，n＝9） and 96.2％-99.5％（RSD＝1.4％，n＝9）. CONCLUSIONS： The improved standard can more effectively control the quality of Kanggu zengsheng tablet.
