title: [Comparison study of different extraction methods of Sarcandra glabra].
abstract: OBJECTIVE
  To compare the different extraction methods of Sarcandra glabra (Thunb.) Nakai.
  
  
  METHODS
  To compare the yield of extraction and determination content of extraction by 6 kinds of different extraction methods as cold-soaked extraction, percolation extraction, reflux extraction, continuous reflux extraction, ultrasonic extraction and microwave extraction, and the content of furmaric acid was determinated as index.
  
  
  RESULTS
  The yields of extraction and contents of availability component were very different through 6 kinds of different extraction methods. Among them, the yields of reflux extraction and continuous reflux extraction were higher, the contents of availability components of ultrasonic extraction and microwave extraction were higher.
  
  
  CONCLUSIONS
  Microwave extraction method is better than other methods. It is fast economical, solvent and energy, and also has higher yield of availability component.
