NEW RESOURCE PLANTS FOR CITRAL AND CINEOLE

The essential oils were extracted by steam distillation from fresh leaves of 3 species of Cinnamomum collected from west Hubei. 4 samples of essential oils, prepared respectively from different producing area, were examined qualitatively and quantitatively by the methods of capillary GC/MS/DS on Finnigan-4510 type. As the result, the major component of 3 samples is citral——the essential oil of C. wilsonii produced from Changyang County contains it 77.99%, the essential oil of C. wilsonii produced from Xianfeng County contains it 86.47% and the essential oil of C. bodinieri var. hupehanum contains it 95.01%. The major component of the essential oil of C. Camphora is 1,8-cineole (65.76%).
