To analyze three essential oils isolated from three different brands' clove samples collected from Gulf region and tested their antimicrobial activities. The essential oils were isolated from powder clove samples by water distillation method and analyzed and identified by gas chromatography-mass spectrometry. Antimicrobial activities of the three isolated essential oils were calculated on the diameter inhibition zone by disc diffusion method against three bacterial strains with amoxicillin standard. Twenty-eight, twenty-two and twenty-six chemical ingredients with high percentage were characterized based on gas chromatography retention time from clove essential oils collected from Saudi Arabia, United Arab Emirate and Jordan. The highest antimicrobial activity was obtained from Saudi Arab against Escherichia coli, Pseudomonus aeruginosa and Staphylococcus aureus and the lowest was from Jordan and the order of antimicrobial activity was Saudi Arabia>United Arab Emirate>Jordan. All three essential oils from Gulf region are containing very portent chemical ingredients and it could be used as medicine or antibiotics for different aliments.
