Özet: The chemical composition of volatiles from the leaves of three different Illicium species has been studied. The essential oils were obtained by hydrodistillation and analyzed by GC (FID) and GC-MS. The components by identified by MS libraries and their LRIs. The essential oil contents vary between 0.12% and 0.21% (v/w), calculated on a dry weight basis. Illicium majus J. D. Hooker & Thomson afforded oil whose major constituents were aromadendrene (13.0%), cuparene (8.2%), 1,8-cineole (8.1%) and calamenene (7.8%). However, 1,8-cineole (8.4%), linalool (7.7%), (E)-nerolidol (7.6%) and sabinene (7.1%) were the quantitatively significant compounds of the leaf oil of Illicium micranthun Dunn. The leaf oil of Illicium tsaii A. C. Smith comprised mainly of (E)-nerolidol (15.5%), β-caryophyllene (8.1%), β-cedrene (6.5%), 1,8-cineole (6.3%) and calamenene (6.3%). The chemical composition of the leaf essential oils of these plants from are being reported for the first time.
