title: [Saponins from roots of Hedysarum multijugum].
abstract: OBJECTIVE
  To study the chemical constituents from the root of Hedysarum multijugum.
  
  
  METHODS
  The compounds were separated by chromatographic methods, their structures were identified by spectral analysis.
  
  
  RESULTS
  Four compounds were isolated and identified as soyasaponin II methyl ester (1), soyasaponin II (2), soyasaponin Bg (3), and soyasaponin I (4).
  
  
  CONCLUSIONS
  The four compounds were obtained from the plant for the first time. Compound 3 was isolated from the genus Hedysarum for the first time, and the NMR data of 3 was reported for the first time.
