This present study was carried out in Khartoum state-Sudan, during March 2019. Phytochemical activities were investigated to detect the effects of antibacterial; this plant was collected from Elsalihen area, locality of Algoze, South Kordofan State, western Sudan. The dried cortex of Xeromphis nilotica was extracted successively with (Ethanol, Ethyl acetate , methanol and distil water,). The phytochemical screening carried out on four different extracts of species cortex and it contain amount of secondary metabolize such as ( alkaloids, Carbohydrate Tannins, Phenol, Sterols & Triterpenes, Saponin, Flavonoids ,Quinine ,Amino acid and Protein were studied .The antibacterial activity of extracts were evaluated against four standard bacteria (Gram positive; Bacillus subtilis, Staphylococcus aureus) and (Gram negative; Escherichia coli, Pseudomonas aeruginosa) and the results showed that there are high inhibition zone (21-19) in ethanol and ethanol extract and low in habitation zone in water extract in all concentration
