title: [Determination of evodiamine and rutaecarpine in Evodia rutaecarpa (Juss.) Benth after compatibility with Coptis chinensis Franch].
abstract: OBJECTIVE
  To studying changes of evodiamine and rutaecarpine in E. rutaecarpa after compatibility with C. chinensis.
  
  
  METHODS
  An YWG C18 column was used with a mobile phase of CH3CN-H2O(40:60), the flow rate was 1.0 ml.min-1 and the detection wavelength was 290 nm.
  
  
  RESULTS
  The average recovery was 97.82% and 97.00%, the relative standard deviation was 0.81% and 1.10% for evodiamine and rutaecarpine respectively.
  
  
  CONCLUSIONS
  The amounts of evodiamine and rutaecarpine were decreased after compatibility with C. chinensis.
