Antimicrobial activity was tested against n-hexane, ethyl acetate, acetone, ethanol and acetone fraction of acetone extract. The investigation is carried out against various gram positive and gram negative bacterial strains ( Escherichia coli ATCC – 11246; Staphylococcus aureus ATCC – 6538 P; Salmonella typhimurium ATCC – 23564; Pseudomonas aeruginosa ATCC – 27853; Proteus vulgaris ATCC – 13315; Bacillus cereus ATCC – 11778) . Disc diffusion method is employed for the detection of antimicrobial activity. Streptomycin was used as standard. The crude acetone extract (3) exhibits activity against Proteus vulgaris and Salmonella typhimurium, while the crude ethanol extract (4) ellucidates antimicrobial activity against Pseudomonous auroginosa.
