title: [Research on method in avoiding the interference of poloxamer in determination of polysaccharides in thermosensitive gel].
abstract: OBJECTIVE
  To study a method in avoiding the interference of poloxamer in determination of polysaccharides in thermosensitive gel and develop an assay correspondingly.
  
  
  METHODS
  After extracting the freeze dried gel with acetic ether, detected it in colorimetric method.
  
  
  RESULTS
  The interference of poloxamer was removed thoroughly, while the retention rate of the polysacchrarides showed to be 100.11% (n = 3). The average recovery was 102.6% (n = 6).
  
  
  CONCLUSIONS
  The method shows to be simple, maneuverable, stable and well reproducible.
