| Abstract: | Two new isoflavone diglycosides, formononetin 8-C-[beta-d-apiofuranosyl-(1 --> 6)]-beta-d-glucopyranoside (1) and formononetin 8-C-[beta-d-xylopyranosyl-(1 --> 6)]-beta-d-glucopyranoside (2), were isolated from the roots of Pueraria lobata, together with four known compounds, 4'-methoxypuerarin (3), daidzin (4), genistin (5), and daidzein (6). The structures of these compounds were elucidated by the spectroscopic methods. |
