ABSTRACT

Purpose: This study is carried out for the purpose to investigate the antibacterial activity of Syzygium cumini L. Leaves. The aim of the study is to evaluate the antibacterial activity and to determine the zone of inhibition of alcoholic extract on some bacterial strains. Methodology: In the present study, microbial activity against the medically important bacteria is determined using the methanolic extract of Syzygium cumini L. leaves by using agar disc diffusion method. Findings: It shows antibacterial activity against 2 Gram positive bacteria - Staphylococcus aureus, Bacillus cereus and 2 Gram negative bacteria Alcaligenes faecalis, Aeromonas hydrophilia pathogenic bacteria. Zone of inhibition of alcoholic extract of leaves is compared with the standard drugs like chloramphenicol, ampicillin, cotrimoxazole and vancomycin for antibacterial activity. After practical, it is observed that the remarkable activity against microbes is shown by the alcoholic extract of the leaves of Syzygium cumini L. The phytochemical of plant is analyzed. The antibacterial activity of leaves due to secondary metabolites present in the Syzygium cumini L. Plant. So, this plant could be useful to discover new antibacterial natural
