title: [Study on chitosan clarification refining the decoction of jiangtangtongmai by homogenous design method].
abstract: OBJECTIVE
  To study the effect of chitosan clarification refining the decoction of Jiangtangtongmai by homogenous design method.
  
  
  METHODS
  The content of catalpol in the refined decoction by the alcohol-precipitation method and chitosan clarification method was determined by RP-HPLC.
  
  
  RESULTS
  Catalpol can be well preserved by chitosan clarification method.
  
  
  CONCLUSIONS
  Chitosan clarification method can replace alcohol-precipitation method in refining of the decoction of Jiangtangtongmai.
