چکیده
A new furanoisoflavone, 2'-methoxy-4',5'-methylenedioxy-[2'',3'':7,8] furanoisoflavone, leptobotryanone (1), and a new natural O-prenylated isoflavone, 4'-γ,γ-dimethylallyloxy-5,7-dihydroxyisoflavone (2), were isolated from the twigs of Millettia leptobotrya, together with twelve known flavonoids, 4'-γ,γdimethylallyloxy-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.

The dichloromethane extract of the stem bark of Millettia usaramensis subspecies usaramensis showed anti-plasmodial activity against the chloroquine sensitive (D6) and chloroquine resistant (W2) strains of Plasmodium falciparum. Chromatographic separation of the extract led to the identification of a new rotenoid, (6aR,12aS)-2,3-methylenedioxy-9-methoxy-8-(3,3-dimethylallyl)-12a-hydroxyrotenoid...
