title: [Isoflavones from vine stem of Millettia dielsiana].
abstract: OBJECTIVE
  To investigate the chemical constituents of vine stem of Millettia dielsiana.
  
  
  METHODS
  Various chromatographic techniques were employed for the isolation and purification of the chemical constituents. The structures were elucidated by chemical and spectral analyses.
  
  
  RESULTS
  Seven isoflavones were isolated and identified as 6-methoxycalpogonium isoflavone A (1), durmillone (2), ichthynone (3), jamaicin (4), toxicarol isoflavone (5), barbigerone (6), genistein (7) respectively.
  
  
  CONCLUSIONS
  Compound 5 was isolated from the genus and Compounds 1-6 were isolated from the plant for the first time.
