title: [Purification of Ganoderma lucidum polysaccharide by ultrafiltration technology].
abstract: OBJECTIVE
  To investigate the feasibility and technology for purifying Ganodermna lucidum polysaccharide (GLP) by ultrafiltration.
  
  
  METHODS
  A spire roll ultrafiltration unit was selected to purify GLP.
  
  
  RESULTS
  Purity of 73.5% and recovery ratio of 69.4% for GLP were obtained by using a membrane with cut-off molecular mass of 6000, while operating temperature, pressure and time were 45-50 degrees C, 0.6 MPa and 45 min, respectively.
  
  
  CONCLUSIONS
  Ultrafiltration is one of the new feasible methods for the purification of GLP.
