The present study was conducted to determine the antibacterial activity of Tribulus terrestris against Pseudomonas aeruginosa. Four different concentrations i.e. 15mg/ml, 20mg/ml, 25mg/ml, 30mg/ml of different extract of water and ethanol extracts of Tribulus terrestris were screened for antibacterial activity by disc diffusion method. Ofloxacin was control drug. Ethanol extract of Tribulus terrestris showed maximum inhibition zone i.e. 27.33mm as compared to aqueous extract. Aqueous extract of Tribulus terrestris showed inhibition zone from 13.66 to 25.66mm but ethanol extract showed 14.66 to 27.33mm inhibition zone. It was concluded that Tribulus terrestris is an effective medicinal plant which shows effective antibacterial activity against Pseudomonas aeruginosa.
