title: [Studies on content determination of polysaccharides in Periploca forrestii].
abstract: OBJECTIVE
  To establish a method for content determination of polysaccharides in Periplocaforrestii.
  
  
  METHODS
  The conversion coefficient of P. forrestii. polysaccharide to glucose was obtained by refined polysaccharides, and then the content of crude polysaccharides was determined by sulfuric-phenol method.
  
  
  RESULTS
  The content of crude polysaccharides in P. forrestii. was 54.68% (RSD 3.0%, n = 6), and the average recovery was 101.7% (RSD 6.0%, n =6).
  
  
  CONCLUSIONS
  The method was simple, rapid, and accurate.
