    Abstract:
    From the roots of Millettia puguensis (Leguminosae), a novel isoflavonoid (5), 2'-methoxy-4',5'-methylenedioxy-7,8-[2-(1-methylethenyl)furo]isoflavone, and four known compounds, i. e., lupeol (1), (-)-maackiain (2), 6,7-dimethoxy-3',4'-methylenedioxyisoflavone (3) and 7,2'-dimethoxy-4',5'-methylenedioxyisoflavone (4) were isolated and identified by 1H-, 13C-NMR and mass spectroscopy. All compounds were evaluated for their antiprotozoal and cytotoxic activities, but only a moderate antileishmanial activity was observed for compound 3 (IC50 = 32 microM against Leishmania infantum), and a moderate cytotoxicity for compound 2 (IC50 = 43 microM on MRC-5 cells).
