abstract: OBJECTIVE
  to set up a determination of tanshinone II A and deoxyschizaadrin in danshenwuweizi tablet by RP-HPLC.
  
  
  METHODS
  two components were separated through Kromasil C18 (250 mm x 4.6 mm, 5 microm) column with methanol-water (85:15) by volume as a mobile phase. The flow rate was 1 ml x min(-1) and the detection wavelength were 270 nm (tanshinone II A) and 254 nm (deoxyschizandrin).
  
  
  RESULTS
  The linear range of tanshinone II A and deoxyschizandrin were 0.3232 microg-1.616 microg and 0.525 microg-2.625 microg, respectively. The average recovery was 99.83% with RSD 0.36% for tanshinone II A and 100.2% with RSD 0.72% for deoxyschizandrin respectively.
  
  
  CONCLUSIONS
  The method is simple, accurate and rapid with good reproducibility. It can be used for the quality control of danshenwuweizi tablet.
