Antibacterial activity of Syzgium aromaticum L. against certain bacterial strains

This study's objective was to assess the antibacterial activity of clove (S. aromaticum) extracts against four distinct bacterial strains: Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, and Klebsiella pneumonia. The extracts were tested in methanol, ethanol, aqueous, and acetone solutions. According to the findings, the methanolic extract out performed the aqueous, acetone, and ethanolic solutions. The agar well diffusion method was used to measure the antibacterial activity. By subtracting the well size (6 mm) from the average value of the inhibition zones, the effective inhibition zone was calculated. The drug concentrations of the plant material corresponded to the growth inhibition zone of the bacteria. As the extract was diluted, a declining trend in the inhibitory zone was seen. Furthermore, the methanolic extract was found to be more efficient.
