Abstract

The bioassay-guided fractionation of methylene chloride extracts of Miconia fallax DC. and Miconia stenostachya DC. led to the isolation of five triterpene acids. The Triterpenes ursolic acid, oleanolic acid and gypsogenic acid were active against blood trypomastigote forms of Trypanosoma cruzi. In contrast, the acetyl and methyl ester derivatives were not found to potentiate the trypanocidal activity. These results suggest the importance of the polar groups for activity.
