The ethanolic extract from Peritrophe bicalyculata leaves was evaluated for the presence of phytochemicals and its antimicrobial activity in vitro against selected bacteria and fungi using the antibiotic gentamycin as control. The extract showed the presence of secondary metabolites such as alkaloid, saponin, tannin and steroid. It also inhibited the growth of the tested microorganisms at different concentrations. However stronger in-vitro activity was recorded against Staphylococcus aureus, Klebsiella spp, Pseudomonas aeruginosa, Aspergillus niger, Asperigillus clavatus and Rhizopus stolonifer. The antimicrobial activity of the plant extract is an evidence of ethnomedicinal potential of the plant.
