Background: Pomegranate (Punica granatum L.) has gained commercial importance in food and health industries due to increasing scientific evidence linking its consumption to better health outcomes. Objective: This study aimed to detect the active substances (phenols, tannins, flavonoids, alkaloids, and saponins) in the pomegranate peel and their effectiveness against bacteria isolated from intestine and stomach which included Salmonella and Escherichia coli, which are responsible for most gastrointestinal diseases. Materials and Methods: The experiment was designed randomly and was statistically analyzed using the least significant difference at P < 0.05. The plant extracts were obtained by alcoholic extraction using Soxholet. The compounds were diagnosed qualitatively and quantitatively using reference methods. Results: The results showed that peels contained high concentration compounds of alkaloid, tannic acid, and saponins. A 15% alcohol extract gave a high inhibition rate compared to the water extract and alcohol at a rate of 40 mm corresponds to 19 mm in the chloroform extract and 20 mm in the water extract at the concentration of 15%. A 15% concentration of alcoholic extract with antacid ampicillin and chlorophyll was compared with high efficacy compared to effective anti-ampicillin.
