Isoflavones from vines of Pueraria lobata

摘要: OBJECTIVE To investigate the isoflavones from vines of Pueraria lobata. METHOD The compounds were isolated by column chromatography over silica gel and RP-C18, purified Sephadex LH-20 preparative TLC. structures elucidated on basis physico-chemical properties spectral data. RESULT Twelve identified as: 3'-methoxydaidzein (1), formononetin (2), genistein (3), daidzein (4), daidzin (5), genistin (6), ononin (7), 5-hydroxyl (8), calycosin (9), 6"-O-acetyl (10), (11), puerarin (12). CONCLUSION For first time, 9-11 genus plant, 1, 3, 6-8 obtained this plant.
