ABSTRACT

This study investigates the antibacterial activity of leaf extracts of syzygium aqueum and Averrhoa carambola extracts against common bacterial pathogens. Both plants have been traditionally used in folk medicine, at their antibacterial properties remain under explored in scientific research. The extracts were prepared using Soxhlet extraction with ethanol as the solvent. Antibacterial activity was evaluated against selected gram positive (lactobacillus acidophilus) and gram negative (klebsiella pneumonia, Escherichia coli) bacterial strains using agar well diffusion method. The minimum inhibitory concentration was determined by dilution method. The antibacterial effects of both plants can be attributed to bioactive compounds. Which were identified through preliminary phytochemical analysis. The crude extracts of syzygium aqueum suppresses the growth of klebsiella pneumonia and Escherichia coli and crude extract of Averrhoa carambola suppresses the growth of lactobacillus acidophilus and klebsiella pneumonia. This shows that the ethanolic extracts of syzygium aqueum and Averrhoa carambola are active against klebsiella pneumonia. This suggest that syzygium aqueum and Averrhoa carambola possess antibacterial properties, supporting their potential use as natural alternatives in treating bacterial infection.
