title: [Enzymatic extraction of baicalein and wogonin from radix scutellariae].
abstract: OBJECTIVE
  The optimum enzymatic extraction of baicalein and wogonin from Radix scutellariae were determined.
  
  
  METHODS
  HPLC method was used to determine the content of baicalein and wogoinin from Radix Scutellariae, 5 factors were studied on enznmalic extraction of celluase.
  
  
  RESULTS
  The optimum enzymatic extraction of celluase were determined as follows enzyme 20U for Ig material, pH 4.8, buffer to raw material ratio20, temperature 50 degrees C, and reaction time 8 h.
  
  
  CONCLUSIONS
  Compared with the traditional water extraction, the extraction yield of baicalein and wogonin increase 5 and 4 times.
