Abstract

Pomegranates (Punica granatum L.) have been celebrated for their medicinal properties for centuries, prominently in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine. This study evaluates the antimicrobial efficacy of solvent extracts from pomegranate peel against pathogenic microorganisms. Extracts were obtained using methanol, ethanol, chloroform, and n-hexane. The antimicrobial activity was assessed against Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Aspergillus niger, Trichoderma viridens, and Candida albicans. The disc diffusion method was employed to measure inhibition zones. Results demonstrate significant antimicrobial activity across all extracts, with methanol and ethanol showing the highest efficacy. Chloroform and n-hexane extracts also displayed notable activity against certain pathogens. Notably, methanol extract showed inhibitory effects on E. coli (P=0.0378, F=3.861), B. subtilis (P=0.0001, F=20.56), P. aeruginosa (P=0.0402, F=3.775), A. niger (P=0.0031, F=8.353), Trichoderma viridens (P=0.0001, F=59.72), and Candida albicans (P=0.0001, F=34.23). Ethanol extract exhibited significant inhibition on E. coli (P=0.0001, F=71.48), B. subtilis (P=0.0003, F=14.76), P. aeruginosa (P=0.0001, F=26.02), A. niger (P=0.0001, F=19.21), Trichoderma viridens (P=0.0001, F=22.44), and Candida albicans (P=0.0002, F=16.60). Chloroform extract showed significant inhibition on E. coli (P=0.0005, F=13.45), B. subtilis (P=0.0456, F=3.602), P. aeruginosa (P=0.0027, F=8.673), A. niger (P=0.0001, F=95.34), and Candida albicans (P=0.0001, F=35.09). Furthermore, n-hexane extract exhibited significant inhibition on E. coli (P=0.0001, F=57.23), B. subtilis (P=0.0120, F=5.662), P. aeruginosa (P=0.0072, F=6.599), A. niger (P=0.0001, F=69.44), and Candida albicans (P=0.0001, F=35.09). These findings underscore the potential of pomegranate peel extracts as natural antimicrobial agents and provide valuable insights for their future application in pharmaceuticals and other industries.
