Abstract
Essential oil was extracted from cones of metasequoia (Metasequoia glyptostroboides) by steam distillation, fragrance was determined by sensorial analysis and chemical compositions were analyzed by gas chromatography-mass spectrometry with solid-phase microextraction apparatus. Metasequia contained 0.40% of essential oil in the cone. Major impact fragrances of the essential oil were woody, coniferous and herbal, and minor impact fragrances were minty, spicy and oily. There were nine constituents in the essential oil : 8 hydrocarbons and 1 oxide. Constituents were limonene (66.18%), ${\delta}$-3-carene (11.11%), ${\beta}$-caryophyllene (6.66%), ${\beta}$-myrcene (5.92%), ${\beta}$-pinene (4.14%), caryophyllene oxide (2.39%), camphene (2.32%), ${\alpha}$-caryophyllene (0.85%), and tricyclene (0.43%). Herbal and minty frangrances could be due to limonene and ${\delta}$-3-carene, spicy frangrance to caryophyllene, woody and coniferous frangrances to ${\alpha}$-pinene and ${\beta}$-pinene, and oily fragrance to camphene.
