title: [Study on the chemical constituents from the aerial parts of Medicago sativa and their hypolipidemic activity].
abstract: OBJECTIVE
  To research the chemical constituents from the aerial parts of Medicago sativa.
  
  
  METHODS
  Various column chromatographies were emoployed to isolate and purify the constituents. Their structures were elucidated by spectral analysis (IR, UV, MS, 1H-NMR, 13C-NMR) and chemical evidence.
  
  
  RESULTS
  Two constituents were obtained and identified as soysaponin I (I), azukisaponin V (II).
  
  
  CONCLUSIONS
  These two compounds are isolated from the arial parts of Mesicago sativa for the first time. Moreover,the compounds are found to have hypolipidemic activity.
