Steam distillation, petroleum ether, and ethanol extracts from Hyptis suaveolens leaves were evaluated for their antimicrobial activity in vitro . Steam distillation extract exhibited broad-spectrum antibacterial and antifungal activity against the tested organisms. It showed highest antifungal and antibacterial activity against Aspergillus niger and Micrococcus luteus, respectively. Activity indices of A. niger against miconazole (25 µg/ml) and M. luteus against chloramphenicol (10 µg/ml) were 0.89 and 0.67, respectively.
