This study aimed to examine the antibacterial effects of constituents obtained from leaves. This goal was achieved by using three organic solvents, namely Ethanol, Ethyl acetate, and Hexane to prevent the growth of the causative urinary tract infections isolates, such as , , , and sp. in Iraq. The fresh leaves collected from different regions of Hillah City, during March 2020, were classified according to the taxonomic features of Iraqi Flora. Extractions were completed by a method of digestion and then the stock solution of 200 mg/mL was prepared in 10% of Dimethylsulfoxide. A Millipore filter (0.22 µm) was used for the sterilization of all the extracts used in this study. Agar well diffusion method was utilized to test the antibacterial effects of the constituents separated from the dried leaves of against the urinary tract infection bacteria at three concentrations of 50, 100, and 200 mg/mL for each extracted constitute by the three different solvents. Dimethylsulfoxide 10% and the meropenem were utilized as the negative and positive controls. Constituents separated by ethanol solvent at 200 mg/mL exhibited significant supremacy (≤0.05) over the meropenem against sp. isolate, and exhibited the same significant difference (≤0.05), compared to the meropenem drug against . Constituents extracted by Ethyl acetate organic solvent at a concentration of 200 mg/mL exhibited a similarly significant effect (≤0.05), compared to the meropenem against sp. isolate. However, the hexane extract was the least effective among the other solvents utilized in this study. The results of the current study revealed that constituents in the leaves of could be considered a valuable herbal remedy for controlling urinary tract infections pathogenic bacteria.
