title: [Study on the extraction of polysaccharides from Marasmius androsaceus Mycelium].
abstract: OBJECTIVE
  To optimize the extraction condition for the polysaccharides from Marasmius androsaceus Mycelium.
  
  
  METHODS
  The single factor tests and response surface methodology (RSM) were applied. Overall research was proceeded by rational desingn. Technological condition parameters were determined according to regression analysis by SAS.
  
  
  RESULTS
  The optimum condition was as follows: extraction temperature was 78 degrees C , extraction-duration was 1. 5h, water to material ratio was 36: 1. The optimum extracting rate for the polysaccharide was 11. 59%.
  
  
  CONCLUSIONS
  The RSM is for optimum extraction process and it will improve the extraction conditions of polysaccharides.
