The essential oils, which extracted from the peels and fleshes of Citrus sudachi, Navel Orange and Citrus iyo, were analyzed by gas chromatography and the following results were obtained. 1) The yields of the essential oil from each peel were 1.2% for C. sudachi, 2.1% for Navel Orange and 1.7% for C. iyo. The amount of the essential oil from each flesh was very little, so the yields from the fleshes weren't calculated. 2) The common compositional characteristic of the essential oils extracted from the peels of the three C. spices, was found that Limonene was contained in large percentage, i.e. 95.5% for Navel Orange, 88.6% for C. iyo and 73.4% for C. sudachi. And among the other components,β-Phellandrene, γ-Terpinene, p-Cymene, α-Pinene and Myrcene were found more in the peel oil of C. sudachi, γ-Terpinene, Myrcene, Linalool and α-Pinene in that of C. iyo. 3) The essential oils from the fleshes of the three C. species, also contained Limonene in large quantity, but the proportion of Limonene in the fleshes was less than that of in the peels i.e. for C. sudachi, 58.4% for C. iyo and 30.7% for Navel orange. The essential oils from the fleshes commonly contained several components which had high boiling point. And the oil from the flesh of Navel orange contained α-Pinene as much as 23.8%, and it was distinctivelly different from the other two.
