[Isoflavones from vines of Pueraria lobata].
OBJECTIVE
To investigate the isoflavones from the vines of Pueraria lobata.


METHODS
The compounds were isolated by column chromatography over silica gel and RP-C18, and purified by Sephadex LH-20 column chromatography and preparative TLC. The structures were elucidated on the basis of physico-chemical properties and spectral data.


RESULTS
Twelve compounds were isolated and identified as: 3'-methoxydaidzein (1), formononetin (2), genistein (3), daidzein (4), daidzin (5), genistin (6), ononin (7), 5-hydroxyl ononin (8), calycosin (9), 6"-O-acetyl genistein (10), 6"-O-acetyl daidzin (11), puerarin (12).


CONCLUSIONS
For the first time, compounds 9-11 were isolated from the genus Pueraria plant, and compounds 1, 3, 6-8 were obtained from the vines of this plant.
