Abstract

The acetone extract of Sophora flavescens Aiton (Leguminosae) exhibited lethal activity against Trypanosoma cruzi. Column chromatographic separation of the extract guided by trypanocidal activity afforded a new prenylated flavanone (4), together with nine known flavonoids: sophoraflavanone G (1), (-) -kurarinone (2), kushenol L (3), 2′-methoxykurarinone, (5), 7,4′-dihydroxy-5-methoxy-8-(γ,γ-dimethylallyl)-flavanone (6), leachianone A (7), 8-prenylnaringenin (8), noranhydroicaritin (9) and alopecurone G (10). The structure of the new flavanone 4 was determined on the basis of spectroscopic analyses. The minimum lethal concentrations of these compounds against epimastigotes of T. cruzi were 3.7 μM (1), 14 μM (2), 7.1 μM (3), 7.2 μM (4), 6.9 μM (5), 71 μM (6), 5.5 μM (7), 18 μM (8), 4.4 μM (9) and 3.6 μM (10).
