RESUMEN
Bioactivity-guided fractionation of an ethanolic extract of Vitis repens led to the isolation of resveratrol (1), 11-O-acetyl bergenin (2), and stigmast-4-en-3-one (3). The compounds were examined for their in vitro antitrypanosomal activities against trypomastigotes of Trypanosoma evansi. Resveratrol showed antitrypanosomal activity with an IC50 value of 0.13 microM, whereas 11-O-acetyl bergenin and stigmast-4-en-3-one exhibited IC50 values of 0.17 and 0.15 microM, respectively.
