Aim Of The Study: Ninety-four ethanolic extracts of plants used medicinally by the Yanesha, an Amazonian Peruvian ethnic group, for affections related to leishmaniasis and malaria were screened in vitro against Leishmania amazonensis amastigotes and against a Plasmodium falciparum chloroquine resistant strain.
Materials And Methods: The viability of Leishmania amazonensis amastigote stages was assessed by the reduction of tetrazolium salt (MTT) while the impact on Plasmodium falciparum was determined by measuring the incorporation of radio-labelled hypoxanthine.
Results And Conclusions: Six plant species displayed good activity against Plasmodium falciparum chloroquine resistant strain (IC(50) < 10 microg/ml): a Monimiaceae, Siparuna aspera (Ruiz & Pavon), A.
