The Chemical Composition and antimicrobial activity of peel essential oil of sweet orange Citrus grown in Peshawar, Pakistan were investigated. The major chemical composition concentration of essential oil were D-Limonene was 95.62%, beta-myrcene was 2.78%, alpha-pinene was 0.75%, n-octyl acetate was 0.32%, beta pinene was 0.2% and beta farnesene was 0.09%. The antimicrobial activity of sweet orange peels oil were evaluated using well diffusion methods towards 4 bacteria and 3 fungal cultures. The results were compared with those synthetic antibiotics Gentamycin, Tetracyclin, Fluconazole and Nystatine. The Salmonella typhi were inhibited by essential oil with inhibition zone 13mm (50µL), 10mm (25µL) and 06mm (10µL). The Staphylococcus aureus ATCC6538 with the inhibition zone were 21(50µL), 18mm (25µL) and 07mm (10µL). No inhibition zone was observed for rest of bacteria E. coli and B. cereus. While all the tested fungal strains were showed a strong resistance to these oils.
