[Isoflavones from vine stem of Millettia dielsiana].
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.
