title: [Study on the initial processing of Corydalis yanhusuo].
abstract: OBJECTIVE
  To establish initial processing technology of Corydalis yanhusuo.
  
  
  METHODS
  Investigated the effect of the factors such as slice method, dry method, drying temperature on the content of water-extract, ethanol-extract, effective component in Corydalis yanhusuo pieces. Compared the quality with that of the traditional initial processing samples.
  
  
  RESULTS
  The best initial process method was: cut fresh Corydalis yanhusuo into 4 - 5 mm thick slices, dry at 70 - 80 degrees C or microwave dry.
  
  
  CONCLUSIONS
  The study provides theoretical base for modifying the initial processing.
