title: [Influence of super fine crushing on the extraction of polysaccharides from polystictus versicolor].
abstract: OBJECTIVE
  To study the extractive technique of Polysaccharides from Polystictus Versicolor pretreated by super fine crushing.
  
  
  METHODS
  Polystictus versicolor was pretreated by technique of super fine crushing, and the contrast examination of super powder (5 microm) and polystictus versicolor was done. Then the extractive technique of polysaccharides from polystictus versicolor super powder was optimized by the orthogonal design.
  
  
  RESULTS
  The extraction yield of Polysaccharides from polystictus versicolor super powder was higher 61% than that of polystictus versicolor. The optimum extractive technique of polysaccharides was 100 degrees C, 80 min and extracting 3 times.
  
  
  CONCLUSIONS
  Technique of super fine crushing is propitious to the extraction of polysaccharides from polystictus versicolor.
