title: [Chemical structure of fructosan from Condonopsis pilosula].
abstract: OBJECTIVE
  To study the polysaccharide of Condonopsis pilosula.
  
  
  METHODS
  The polysaccharide, CPP-1, was purified by DE-52 cellulose and Sephadex G-200 gel column chromatography. Purity and molecular weight of the polysaccharide were determined by gel permeation chromatography. Methylation analysis, periodate oxidation and degradation, IR, 1H-NMR and 13C-NMR methods were adopted to elucidate the chemical structure.
  
  
  RESULTS
  The molecular weight of CPP-1 was estimated to be 7.5 x 10(4), and the structure of CPP-1 was a beta-(2 --> 1) linked beta-D-fructosan.
  
  
  CONCLUSIONS
  CPP-1 was a neutral homosaccharide.
