 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 main constituent, neryl acetate was not a key odorant despite its content of 30%! The 1,3-diketones (specific components of Helichrysum oilsare key odorants of the essential oil...
