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). \\ | 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 concentration of these compounds is higher during the flowering stage and quite higher in the flowers than in the stems. Therefore, the distillation of flowers and stems together does not affect the commercial quality. Type A oils could be used in cosmetics and aromatherapy, | ||

"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, | "The chemical composition of the everlasting essential oils from Greece and Croatia are quite different.

+ | "The results obtained showed a difference in the composition of the essential oils of H. italicum from Elba Island, mainly due to the environment where the plant grows, and, in particular, to the soil type. These hypotheses were further confirmed by the comparison of these oils with essential oils obtained from H. italicum collected on other islands of the Tuscan archipelago." | ||
