The aim of this work was to determine the volatile constituents of fresh and dried (shade dried) fruits of Magnolia kobus DC. using gas chromatography-mass spectrometry (GC-MS). Essential oils from fresh and dried fruits of M. kobus were obtained by steam distillation and the yields were 0.81 and 1.73% (v/w), respectively. GC-MS analysis revealed the identification of seventeen components from both the fresh and dried fruits of M. kobus, which were mostly monoterpene hydrocarbons (62.8–71.8%). A comparison of oils from fresh and dried fruits exhibited the changes in the amounts of several constituents. Major components of the essential oil were α-pinene (26.7–31.6%), β-pinene (20.2–27.9%) and limonene (8.6–10.0%). In the dried sample, concentration of α-pinene, β-pinene, caryophyllene, camphene, and α-humulene contents were decreased. On the other hand, limonene, α-terpineol, bornyl acetate and terpinen-4-ol contents were increased in the dried sample. The present investigation clearly suggested that the drying treatment decreased the concentration of major components in the essential oil of M. kobus fruit.
