Objective To establish a HPLC method for the determination of tanshinone A in compound nephritis tablets. Method : The mobile phase was methanol-water (80:20) and the detection wavelength was 270 nm. RESULTS: The calibration curve for tanshinone A was linear in the range of 0.044488 to 0.242 mg, with r=0.9999 (n=5). The average recovery was 98.9% and the RSD was 1.5% (n= 6). Conclusion : This method is effective, accurate and simple
