EVALUACIÓN DE LA ACTIVIDAD LEISHMANICIDA DE LOS EXTRACTOS ETANÓLICOS DE Rollinia rufinervis SOBRE Leishmania chagasi EVALUATION OF THE LEISHMANICIDAL ACTIVITY OF THE ETHANOLIC EXTRACTS OF Rollinia rufinervis ON Leishmania chagasi

In this study the bioactivity of the fractions obtained from the ethanolic extracts of the leaves, of the trunk bark and of the root bark of Rollinia rufinervis (An nonaceae) is evaluated. It is found that they show cytotoxic activity and that the presence of acetogenins can cause the antiparasitaire activity. The fractions are tested at concentration between 0.095 "g/mL and 100 "g/mL aga inst promastigotes of Leishmania chagasi, evaluatin g
