An attempt was made to analyze the antibacterial potential of Gmelina arborea leaf extracts against human bacterial pathogens viz., Staphylococcus haemolyticus, Staphylococcus lentus, Eschericia coli, Serratia marcescens, Enterobacter amnigenus, Klebsiella pneumoniae, Klebsiella oxytoca, and Brevibacterium paucivorans. Antibacterial study was carried out by disc diffusion and plate hole diffusion assay against selected bacterial pathogens using the solvents acetone, ethyl acetate, ethanol and chloroform extracts. The results of the present study showed the presence of wide spectrum of antibacterial activities against all the above bacterial pathogens studied. In both the methods, the maximum zone of inhibition was observed in ethyl acetate and ethanol extracts against Eschericia coli, Staphylococcus haemolyticus, Klebsiella oxytoca and Brevibacterium paucivorans. It was observed that the inhibition zones of ethyl acetate leaf extracts showed more significant activity than the standard antibiotic chloramphenicol.
