Antibacterial Activity of Borassus Flabellifer

Background: The present study was carried out to evaluate the antibacterial properties of different extracts of Borassus flabellifer belonging to the family Arecaceae, which has been using to treat different illnesses.Methods: The root part was selected for the antibacterial activity and different extracts were prepared using soxhlet extraction procedure using different solvents successively and those were tested for their antibacterial property using agar well diffusion method at different concentration on standard human pathogenic bacterial strains. The zones of inhibitions for tested extracts were measured for each concentration on each bacterial strain tested in millimeter (mm) and showed zone of inhibitions were compared with the standard drug, ciprofl oxacin.Results: The chloroform extract showed less activity compared to ethyl acetate and ethanol extracts at low concentrations, but as the concentration increases the bactericidal activity was increased. The extracts showed more activity at 40mg/100μL. Among all extracts methanol extract showed more,but compared to ciprofloxacin the results on tested bacterial strains are not excellent. The extracts also showed more activity on gram negative bacterial strains. The extracts showed more activity on S.typhimurium and S. pneumoniae and lower activity on S. aureus and E. coli.Conclusion: The results of the present study provides the evidence on antibacterial property of selected medicinal plant if they use in higher concentrations and there is a scope to further studies onisolation of antimicrobial compounds from this species.
