Background and Objective: Medicinal plants have been known to cure many diseases due to the presence of active bio constituents, the goal of this study to detect and evaluate the effectiveness of antimicrobial activity of some Sudanese medicinal plants. Materials and Methods: Methanolic extracts of the following types of local medicinal plants Artemisia herba-alba, Cyperus rotundus, Cymbopogon schoenanthus sb sp. Proximus, Trigonella foenum-graecum, Nigella sativa, Hyphaene thebaica, Nauclea latifolia and Ziziphus spina-christi were tested against eight types of bacteria that were isolated from the same plants as their pollutants. Cup-plate method was used and then the inhibition zone of each plant was measured and compared with the inhibitory zone of some antibiotics used for the same isolates. Results: Methanol extracts of some plant species showed antibacterial activity against most of the studied bacterial species. Cymbopogon schoenanthus ssp. Proximus showed antibacterial activity against most isolated bacterial species in comparison with commercial antibiotics used. Conclusion: According to the findings of this research, severalmedicinal plants have efficacy and effect on certain types of bacteria and are superior or comparable to certain types of antibiotics. When compared to the other medicinal plants used in this study, Cymbopogon schoenanthus sbsp. proximus has the highest activity on most types of Gram-positive and Gram-negative bacteria, as well as the superiority of some antibiotics.
