The composition of 21 essential-oil samples isolated from Helichrysum italicum collected in seven locations of Elba Island (Tuscany, Italy), characterized by different soil types, during three different periods (January, May, and October 2010) was determined by GC-FID and GC/EI-MS analyses. In total, 115 components were identified, representing 96.8-99.8% of the oil composition. The oils were characterized by a high content of oxygenated monoterpenes (38.6-62.7%), while monoterpene and sesquiterpene hydrocarbons accounted for 2.3-41.9 and 5.1-20.1% of the identified constituents, respectively. The main oxygenated derivatives were nerol (2.8-12.8%) and its ester derivative neryl acetate (5.6-45.9%). To compare the chemical variability of the species within Elba Island and between the island and other localities within the Mediterranean area, studied previously, multivariate statistical analysis was performed. 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.
