Abstract
As a part of a research on anti-protozoan agents, the acetonic extracts from Jasonia glutinosa aerial parts (Asteraceae) were tested in vitro against Entamoeba histolytica, Leishmania donovani (promastigote forms) and Trichomonas vaginalis. The 20% acetone extract was not effective at the assayed concentrations. The pure acetone extract was found to be active against Leishmania donovani and Entamoeba histolytica.
