Abstract: The essential oils from 3 varieties Osmanthus fragrans Lour. in Jiang Xi province were obtained by hydrodistillation and analysed by GC-MS. Main compounds of O. fragrans var. thunbergii were linalool oxide, geraniol, α-ionone, β-ionone, dihydroactinidiolide, butyl phthalate, etc. Main aroma components were geraniol, α-ionone, β-ionone, δ-decalactone and linalool oxide. The compounds of O. fragrans were linalool oxide, epoxylinalol, decalactone, β-ionol, β-ionone, diisobutyl phthalate, etc. Main aroma components were β-ionone, diisobutyl phthalate and linalool oxide. The compounds of O. fragrans var. semperflorens were geraniol, theaspirane, β-ionol, dihydroactinidiolide, decalactone, 4-(2,6,6-Trimethyl-cyclohex-1-enyl)-butan-2-ol, etc. Main aroma components were β-ionol, geraniol and theaspirane.
