Antibacterial activity of methanolic leaf; stem bark and root bark extract of Butea superba Roxb., was evaluated through disc diffusion method. Prelimenery phytochemical tests revealed the presence of alkaloids, saponina, sterols and tannins at different concentrations. Antibacterial activity was tested against gram +ve and gram -ve organisms. The methanolic leaf extract exhibited maximum activity against Staphylococcus aureus(NCIM-2079) Stem bark methanolic extract on Enterobacter aerogenes(NCIM-2340) and root bark extract on Enterobacter aerogenes (NCIM-2340). All the extracts tested exhibited concentration dependent activity against tested organisms.
