Background: Medicinal plants have a powerful and synergistic effect against most microorganisms due to the presence of phytochemicals they contain. The inappropriate use of antibiotics possess a significant increase in antibiotic resistance globally, gives to scientists a signal to search alternative therapeutic drugs from medicinal plants. Therefore, formulating alternative antibiotics extracted from herbal medicines for treating such infectious disease in an effective and comfortable manner is being essential.

Methodology: Three plant leaves (Chenopodium murale, Malva parviflora and Lannea furticosa) were collected and extracted using standard methods and the yield was obtained. Phytochemical analysis was done to see the presence of phytochemical compounds in the plants selected. The extracted ingredients were then subjected to the standard bacterial strains to determine their antibacterial activity by measuring the zone of inhibition they possess.

Results: Leaves of Lannea fruticosa gave the highest yield in all the extracts, (22.6%), chloroform extract (7.6%), ethanol-aqueous extracts (19.04%). This plant also produced a maximum zone of inhibition of 34mm and 24mm at the highest concentration (400mg/ml) in aqueous extract against both P. aeruginosa and S. aureus respectively. Besides, all the plants had all phytochemical constituents.

Conclusion: All the selected traditional medicinal plants had a remarkable antibacterial effect due to the presence of phytochemicals they contain which gives them a potency to have a considerable effect against the UTIs causing infectious organisms.
