The essential oil from the fruit of Machilus thunbergii Sieb. et Zucc. grown of Ibaraki-city (Osaka prefecture), has been studied. The constituents of each essential oil, which was obtained respectively from the mesocarp, seed and leaf by steam distillation, were investigated by chromatographic and spectral methods. As a result, 77 compounds were identified. The major components in the mesocarp oil were α-pinene, β-pinene, α-phellandrene, cis-β-ocimene, trans-β-ocimene and α-zingiberene, those in the seed oil were α-pinene, α-copaene, caryophyllene, δ-cadinene and caryophyllene oxide, while those in the leaf oil were caryophyllene, germacrene-D and δ-cadinene. Seasonal variation of the oil content was examined. The oil content decreased with ripening of the fruit. This tendency is similar to the result, which was observed in the fruit of Lindera strych-nifolia (Sieb. et Zucc.) F. Vill. The content of α-phellandrene and trans-β-ocimene, which were the main constituents in the whole fruit oil, increased with the ripening of the fruit, but decreased in the over-mature oil.
