Abstract

In the present study, an extensive in vitro antimicrobial profiling was performed for three medicinal plants grown in Cuba, namely Simarouba glauca check for this species in other resources , Melaleuca leucadendron check for this species in other resources and Artemisia absinthium check for this species in other resources . Ethanol extracts were tested for their antiprotozoal potential against Trypanosoma b. brucei, Trypanosoma cruzi check for this species in other resources , Leishmania infantum check for this species in other resources and Plasmodium falciparum check for this species in other resources . Antifungal activities were evaluated against Microsporum canis check for this species in other resources and Candida albicans check for this species in other resources whereas Escherichia coli check for this species in other resources and Staphylococcus aureus check for this species in other resources were used as test organisms for antibacterial activity. Cytotoxicity was assessed against human MRC-5 cells. Only M. leucadendron extract showed selective activity against microorganisms tested. Although S. glauca exhibited strong activity against all protozoa, it must be considered non-specific. The value of integrated evaluation of extracts with particular reference to selectivity is discussed.
