Abstract: The Acaianilotic from the Mimosaceaefamily is a wild plant that grows in northern and central Sudan. Trees of thorny leaves are alternating, compoundeep-furrowed between the seeds, containing several active substances in its different parts, such as a number of flavonoids and phenolic substances in the leaves, and materials Such as tannins, organic acids such as gallic acid in fruits, fatty acids in seeds. This study aimed to show the importance of the Acacianilotica and its important role for the human being by using it in the field of scientific research and trying to identify the compounds present in the fruits of the Acacianilotica plant, and to study its effectiveness and use against some types of human pathogenic bacteria in terms of studying ethanol extract (80%) (70%) and petroleum ether and distilled water of the fruits. The plant (Acacianilotica) and its ability to inhibit and stop the growth of some pathogenic bacteria, and to identify and detect the active compounds present in the fruits of this plant.The results showed that the ethanol extract (70%) contains esters, soaps, tannins, flavonoids and carbohydrates, while ethanol extract (80%) contains saponins, alkaloids and flavonoids. Petroleum ether extract showed the presence of esters, tannins and flavonoids. As for the distilled water extract, it contained alkaloids, saponias, tannins, flavonoids and carbohydrates, and when studying the anti-bacterial activity, the results showed that ethanol extract (80%) at different concentrations (100, 50, 25, 12.5 mg / mL), the highest inhibition diameter was 15 mm against Escherichiacoli bacteria at 100 mg / mL and the lowest inhibition diameter of 9mm against Staphylococcuscoli bacteria at concentrations 12.5mg / mL.The results of a study of the antibacterial activity of (70% )ethanol extract and ether Petroleum at concentration of 100 mg / mL, showed that the highest inhibition diameter of (70%) for ethanol was 17 mm against Bacillus subtilis, and the lowest diameter of inhibition of ethanol is 10 mm against Escherichia coli. As for distilled water, the highest inhibition diameter was 14 mm against Bacillus subtilis and the lowest diameter of inhibition is 10 mm against Escherichiacoli and Staphylococcusaureus at a concentration of 100 mg / mL. As for the petroleum ether extract of the fruit of the plantshowed the largest inhibition diameter was 15 mm against Bacillus subtilis and the lowest inhibition diameter was 10 mm against Staphylococcuscoli bacteria, from the previous results, it is noted that the ethanol extract of the fruit of the plant at two concentrations (70%) and (80%) is rich in a large number of active substances and has great activity against pathogenic bacteria and that the diameter of inhibition is directly proportional to the concentration of each type of The bacterium Gram + Ve, Gram -Ve, i.e. the diameter of inhibition increases with increasing concentration. In order fruits of the plant to contain many active substances and their effectiveness against the pathogenic bacteria to humans..
