Abstract
The first phytochemical investigation on the vine stems of Millettia dorwardi Coll. et Hemsl led to the isolation of ten flavonoids (isoafrormosin 1, formononetin 2, afrormosin 3, padmakastein 4, liquiritigenin 5, 4H-1-Benzopyran-4-one,7-hydroxy-5,8-dimethoxy-3-(4-methoxyphenyl)-isoflavone 6, 4H-1-Benzopyran-4-one,7-hydroxy-3-(3-hydroxy-5-methoxyphenyl)-6-methoxy 8, 4H-1-Benzopyran-4-one,6-methoxy-3-(4-methoxyphenyl)-6,4′-dimethoxyisoflavone 9, irisolidone 10, prunetin 11), one heterocycle (5-5′-dibuthoxy-2-2′-bifuran 7) and one new isoflavone glycoside (4H-1-Benzopyran-4-one,5-hydroxymethyl-3-(4-methoxyphenyl)-6-β-d-glucopyranoside-isoflavone 12). Their structures were determined by extensive analysis of their spectroscopic data. Among them, compounds 4, 6-10, 12 were for the first time isolated from this genus. The chemotaxonomic importance of these compounds was also summarized.
