title: [Chemical constituents from Polygala telephioides].
abstract: OBJECTIVE
  To study the chemical constituents of Polygala telephioides.
  
  
  METHODS
  The compounds were isolated and purified on macroporous resin, silica gel, Sephadex LH-20, Chromatorex ODS column chromatograph and the structures were determined based on the spectral and chemical evidences.
  
  
  RESULTS
  Four compounds were obtained and characterized as telephiose G, telephiose D, isomangiferin, quescetin 3-O-beta-D-glucopyranoside, respectively.
  
  
  CONCLUSIONS
  Compounds 2-4 were obtained from this plant for the first time and the compound 2 (telephiose G) was a new compound.
