The medicinal plant Parkia biglobosa (Jacq.) was screened for the phytochemical components and antibacterial activity against Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa which are associated with urinary tract infections. Aqueous solutions are more potent than methanolic solutions and activity is concentration dependent. P. aeruginosa is least susceptible than the other organisms.

Key words: Antibacterial activity, Parkia biglobosa, phytochemical, urinary tract infections.
