Essential oils have broken ground in the field of natural product chemistry due to their great importance in pharmaceutics, beauty, food, liqueurs, flavours, and perfumery. In this study, essential oils were extracted from the leaves of five citrus species; Citrus hystrix, Citrus tangelo, Citrus reticulata, Citrus aurantifolia and Citrus limon using hydro-distillation method, the chemical composition of the oils was determined using GC-MS and the oils were tested against Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Candida albicans, and Aspergillus niger to determine their antimicrobial activities at different concentrations to determine their medicinal potentials. 57 compounds were identified in all the citrus species investigated, Citrus hystrix, Citrus tangelo, Citrus reticulata,Citrus aurantifolia, and Citrus limon were found to contain linalool, β-ocimine,γ-terpinine, phytol and 1-ethoxyhexane as the highest occurring components with 98.135%, 83.920%, 29.294%, 20.381%, and 15.180% respectively. All the oils showed strong antimicrobial potentials against all the microorganisms and this indicates that essential oils of the citrus species investigated are potential sources of drugs to cure diseases caused by test organisms.
