The objective of the study was to evaluate antibacterial activity of aqueous and methanol extract of Eryngium foetidum against E. coli, Staph aureus and Ps. aeruginosa. Phytochemical screening was done followed by antibacterial activity by disc diffusion method. Three different concentrations of the plant extracts were taken and for comparison ciprofloxacin, ceftriaxone, ampicillin and amikacin were taken as standards. The zone of inhibition was measured for their antibacterial activity. The methanol extract of Eryngium foetidum showed mild to moderate antibacterial activity against Staph. aureus whereas there was no antibacterial activity shown by aqueous extract. Phytochemical screening of the plant revealed the presence of tannins, saponins and triterpenoids. The results of this study concludes that methanol extract of Eryngium foetidum possess antibacterial activity against gram positive bacteria and further studies are required to confirm the phytoconstituents responsible for its antibacterial activity.
