The aim of present investigation was to evaluate the antibacterial activity of methanolic extracts of leaves, flowers and seeds of Moringa concanensis Nimmo belonging to the family Moringaceae. The antibacterial activity of the extracts was studied by using pathogenic bacterial strains such as Staphylococcus aureus (MTCC 737) and Escherichia coli (MTCC 433). Using disc diffusion method, different concentration of the extracts (20, 30, 40 and 50 mg/μl) was compared with the control Streptomycin. The extracts showed potential antibacterial properties comparable with that of standard Streptomycin against the test organisms. The methanol extract of leaves and flowers of M. concanensis showed that higher antibacterial activity when compared to the seed extracts.
