To establish the quality standard of Yuxia capsules. Methods: Radix stephaniae tetrandrae(Fang Ji)and Radish Seed(Laifuzi) were identified by TLC and the contents of Tetrandrine and Fangchinoline were detremined by HPLC. Results: The TLC chromatography was exclusive and the blank test showed no interference. The detremination of fangchinoline kept good linear relation in the content ranges of 24～84 μg/mL r =0.9992. The average recovery test of fangchinoline was 102.3%, RSD=2.57%.The detremination of tetrandrine kept good linear relation in the content ranges of 34.5～207.0 μg/mL, r =0.9999. The average recovery test of tetrandrine was 102.3%, RSD=2.57%. Conclusion:The established qualitative methods are simple, fast, accurate and with good reproducibility which can be used for the quality control of Yuxia capsules.
