| Abstract | A new furanoisoflavone, 2'-methoxy-4',5'-methylenedioxy-[2 '',3 '':7,8] furanoisoflavone, leptobotryanone (1), and a new natural O-prenylated isoflavone, 4'-gamma,gamma-dimethylallyloxy-5,7-dihydroxyisoflavone (2), were isolated from the twigs of Millettia leptobotrya, together with twelve known flavonoids, 4'-gamma,gamma-dimethylallyloxy-5-hydroxy-7-methoxyisoflavone (3), 2',6,7-trimethoxy-4',5'-methylenedioxyisoflavone (4), 2',7-dimethoxy-4',5'-methylenedioxyisoflavone (5), maximaisoflavone B (6), medicarpin (7), maackiain (8), genistein (9), biochanin A (10), prunetin (11), chrysoeriol (12), kaempferol (13) and desmoxyphyllin A (14) The structures of new compounds were elucidated on the basis of spectroscopic data interpretation, including 1D and 2D NMR and HREIMS. This is the first phytochemical investigation of this plant. |
