title: [Studies on flavoniod constituents of Hedysarum multijugum].
abstract: OBJECTIVE
  To study the chemical constituents from Hedysarum multijugum.
  
  
  METHODS
  The compounds were separated by chromatography methods, their structures were identified by spectral analysis.
  
  
  RESULTS
  Six compounds were isolated and identified as beta-sitosterol (1), 7-hydroxy-4'-methoxy isoflavone (2), betulic acid (3), 1,7-dihydroxy-3, 9-dimethoxy pterocarpene (4), 5, 7-dihydroxy-8-C-prenyl-4'-methoxy isoflavone (5) and 5, 7-dihydroxy-4'-methoxy isoflavone (6).
  
  
  CONCLUSIONS
  Compound 4 is a new compound and the others were obtained from the plant for the first time.
