+"...Corsican oils were found to contain neryl acetate as predominant compound, with amounts from 15.8% (from plants in stage of early shoots) to 42.5% (in full flowering period). In a second part, we sampled Helichrysum italicum subsp. italicum from three locations over the growth cycle of the plant. Significant variations were observed in the concentration of the main constituents, pointing out a chemical composition of oils produced from plants in early shoots (higher amounts of ketones and β‐diketones [like 3,5-dimethylheptan-2,4-dione and 4,6-dimethyloctan-3,5-dione]) different from that obtained from samples harvested in the stages of flowering (higher contents of neryl acetate)." \\

 Tuscan Helichrysum italicum subsp.italicum oils exhibited high contents of sesquiterpene hydrocarbons (23-38%) with significant amounts of β-selinene (7-12%), β-caryophyllene (5-11%) and α-selinene (5-8%). The major compounds were α-pinene (53.5% max) or neryl acetate (22.0% max). \\

 "The chemical composition of the everlasting essential oils from Greece and Croatia are quite different. Oil from Croatia is similar to the oil of Italian origin and its chemical composition varies in relation to the geographic origin and vegetation cycle...The yield of the essential oil obtained by hydrodistillation was 0.21% (w/w) and forty four compounds were identified. The main compounds were: α-pinene (12.8%), 2-methylcyclohexyl pentanoate (11.1 %), neryl acetate (10.4%), 1,7-di-epi-α-cedrene (6.8%), thymol (5.4%), eremophilene (4.3%), limonene (4.0%), 2,3,4,7,8,8a-hexahydro-1H-3a,7-methanoazulene (3.1%), α-bergamotene (2.6%) and ar-curcumene (2.3%). Everlasting essential oil exhibited a very complex composition... Seven esters were identified, representing 29.0% of the total oil. 2-Methylcyclohexyl pentanoate and 2-methylcyclohexyl octanoate were tentatively identified. Furthermore, thymol (5.4%), eleven free alcohols (mono- and sesquiterpene alcohols) and six acids - (E)-2-methyl-2-butenoic, octanoic, decanoic, undecanoic, dodecanoic and tetradecanoic acid - were found, representing 3.7% of the total oil." \\

 The main compounds of 21 essential oil samples isolated from Helichrysum italicum ssp.italicum collected in seven locations of Elba Island were α-pinene (1.0-32.9%), limonene (0.4-12.9 %), 1,8-cineol (tr-18.2%), linalool (1.1-6.7%), nerol oxide (tr-2.8%), nerol (2.8-12.8%), neryl acetate (5.6-45.9%), neryl propionate (1.9-7.7%), ɣ-curcumene (1.0-7.2%), ar-curcumene (0.5-6.7%), and rosifoliol (eudesm-5-en-8-ol, 1.8-17.2%). Neryl isovalerate (sour sweaty floral rose) was found at 0.1-1.3%.\\

+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. \\
