The extraction and characterization of limonene from Citrus species: sweet orange (Citrussinensis), lemon (Citrus limon) and lime (Citrus aurantifolia) fruit peels form the basis of this work. The Citrus fruits (sweet orange, lemon and lime) were obtained from Eke Ekwulobia market, in Aguata LGA of Anambra State which is in the Southeastern part of Nigeria. The peels were removed from the fruits and limonene was extracted from the peels of the three different fruits through simple distillation method. The results for the percentage yields of limonene from the different citrus peels showed that sweet orange peels have the percentage yield of 1.13%, lemon peels have the percentage yield of 0.76% and lime peels 0.69%. The limonene was characterized and the results showed that the limonene has citrus aroma, neutral to both blue and red litmus papers, changed the colour of potassium permanganate from purple to brown which is a positive test for unsaturation, reacted with conc. H2SO4 and CHC
