Abstract The essential oils obtained separately from the leaves and the fruits of Athamanta sicula L. collected in Sicily were studied by capillary GC/MS. The main component in the leaf oil was myristicin (97.6%), while Î²-pinene (2.8%), Î²-phellandrene (5.8%), Î´-3-carene (22.6%), terpinolene (20.5%) and myristicin (41.3%) were the main components of the fruit oil.
