title: [Studies on extraction process of Fructus Schisandrae chinensis and Fructus Ligustri lucidi in gandening tablet].
abstract: OBJECTIVE
  To optimize the combined extraction methods of Fructus Schisandrae Chinensis and Fructus Ligustri Lucidi.
  
  
  METHODS
  The extraction effects of three processes (SFE CO2, alcohol-extraction, water-extraction) were compared by the contents of deoxyschizandrin, the dried extraction yield and production feasibility.
  
  
  RESULTS
  The method of alcohol-extraction was the best of the three methods, and the extraction conditions were optimized by orthogonal design as follows: sixfold 90% alcohol for two times and each for one hour.
  
  
  CONCLUSIONS
  The extraction method is steady and feasible, which can be used for reference for the extraction process of Fructus Schisandrae Chinensis and Fructus Ligustri Lucidi.
