In the present study various extracts of Cyperus esculentus  L. such as acetone, 50%  ethanol, chloroform and petroleum ether were evaluated for their antibacterial activity against several human pathogens such as Escherichia coli, Staphylococcus aureus, Salmonella sp, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa and Citrobacter freundii, by using disc diffusion method. The activity of the samples were compared with that of standard antibiotics. The qualitative phytochemical analysis was also carried out with all the extracts of the sample. Of all the extracts 50%*nbsp; ethanol and acetone extract were found to be rich in phytochemicals such as alkaloids, flavonoids, phenols, tannins, steroids, terpenoids and glycosides. Acetone extract showed highest inhibitory activity against S.aureus, ILpneumoniae and P.vulgaris. 50%  ethanolic extract showed maximum activity against PL.coli, S.aureus and Salmonella sp. Chloroform extract maximally inhibited the growth of S.aureus whereas, petroleum ether extract showed positive results against Salmonella sp respectively. All extracts were sensitive to C. freundii .
