Abstract: The white flowers of Michelia alba DC. Are noted for their strong fragrance and they are widely cultivated in South and Southwest China. The essential oil obtained from the flower is used in teaperfuming as well as in making highly prized perfume. Yellowish oil was acquired with 0.24% yield by steamdistillating the flowers. The essential oil was analysed by means of GC/MS/DS. As a result, 24 constituents were identified as follows: methyl 2-methylbutyrate, campbene, β-pinene, α-phellandrene, β-myrcene, limonene,. 1,8-cineole, ocimene, △3-carene, o-cymene, α-cubebene, cis-linalool oxide, α-ylangene, trans-linalool oxide, β-cubebene, linalool, cis-caryophyllene, β-selin- erie, δ-cadinene, trans-carveol, methyl, eugenol, β-bisabolene, methyl isoeugenol, isoaristolene.
