Ethanolic extracts of the leaf, stem and root bark and the combination of the three parts of Anogeissus leiocarpus were investigated for in vitro antibacterial activity against clinical isolates of Staphylococcus aureusEscherichia coli andPseudomonas aeruginosa using agar diffusion techniques. The extracts of the plant parts showed higher antibacterial activity against S. aureus (15.80 0.85) than other tested organisms. The plant parts generally were found to contain important bioactive substances such as glycosides, phenols, tannins, saponins, alkaloids, steroids, ellagic acids and anthraquinones. These agents may be responsible for the antibacterial activity of this plant.
