title: [Studies on chemical constituents of Hedysarum polybotrys].
abstract: OBJECTIVE
  To study the chemical constituents of Hedysarum polybotrys Hand.-Mazz..
  
  
  METHODS
  The compounds were separated with Sephadex LH-20 and silica gel column chromatography, and their structures were identified on the basis of spectral analysis.
  
  
  RESULTS
  Five compounds were identified as hedysalignan A (1), isoliquiritigenin (2), formononetin (3), calycosin (4) and ononin (5).
  
  
  CONCLUSIONS
  Hedysalignan (1) is a new compound and the others were obtained from the plant for the first time.
