title: [Conditions for extraction of ergosterol from fruits of Ganoderma lucidum using supercritical fluid extration].
abstract: OBJECTIVE
  To study the feasibility of supercritical fluid extraction (SFE) for extraction of ergosterols from the fruits of Ganoderma lucidum.
  
  
  METHODS
  Optimum extraction conditions were studied by orthogonal tests, the ergosterol were analyzed by RP-HPLC.
  
  
  RESULTS
  The optimal extraction conditions were pressure as 20 MPa, temperature at 45 degrees C, using ethanol as modifier carrier at the volume of 1 mL x g(-1), and 1.5 hour of extraction time.
  
  
  CONCLUSIONS
  SFE has the superiority of adjustable polarity, and has the ability of extracting ergosterol from fruits of Ganoderma lucidum.
