title: [Optimization of extraction process for compund kaliziran gel with orthogonal design].
abstract: OBJECTIVE
  To optimize the extraction process of compund kaliziran gel.
  
  
  METHODS
  Orthogonal design was used to optimize the extracting process of eight herb medicines with the extract yield, the content of psoralen, isopsoralen and osthole as indexes, and to optimize the extracting process of Polygonum multflorumi and Seman sinapis albae with the extract yield and the content of 2,3,5,4'-tetrehydroxy-stilbene glucoside as indexes.
  
  
  RESULTS
  The optimum extraction progress was as follows:eight herb medicines were extract 2 times for 1 hour with 8 times of 60% alcohol; P. multflorumi and S. sinapis albae were extract 2 times for 1 hour with 8 times of 40% alcohol.
  
  
  CONCLUSIONS
  The optimum extraction processes are stable and feasible.
