+Neryl acetate as the main component (30.4%) of a steam distilled essential oil of Helichrysum italicum subsp. italicum from Corsica was not a key odorant (only 2 of 10 panelists detected a weak odor zone by GC-O). The most odor-active constituents perceived by all of the panelists and showing the highest mean Flavor Dilution factor were 4,6-dimethyloctan-3,5-dione (0.7%, curry plant-like), 1,8-cineole (1.0%, menthol floral), and nerol (3.7%, lemon floral). Other odor-active constituents were α-pinene (2.1%, lemon floral), p-cresol (trace, sweat spicy curry), linalool (2.4%, orange blossom, citrus), eugenol (0.1%, spicy fruity), and β-damascenone (only detected by GC-O, fruity rose) and another eleven compounds which could not be identified. \\
