title: [Extracting techniques for optimizing zi shen granule by orthogonal text].
abstract: OBJECTIVE
  To optimize the extracting techniques for Zi Shen Granule.
  
  
  METHODS
  By taking the rate of extractum and the total of anthraquinone as the indexes components, the extraction techniques were optimized for Zi Shen Granule through L9 (3) 4 orthogonal text.
  
  
  RESULTS
  The best condition is twice extraction by 2h or 1.5 h, to add octuple water. Then the water solution was concentrated to relative concentration 1.10, and adds ethanol to 70% alcohol Concentration,then stewing 24h.
  
  
  CONCLUSIONS
  The optemized extraction technique is rational and jarless and ideal for mass production.
