Abstract:
The essential oil composition of three spontaneous species growing in an abandoned mining of Elba island was analyzed by GC–MS. A total of 194 compounds were identified representing 73.7–100% of the whole oil composition. The essential oils of Cistus salvifolius and Dittrichia viscosa from this site showed different profiles in comparison with those from not polluted area, where oxygenated sesquiterpenes were the main class. Volatiles from D. viscosa growing in ex-mining area presented 10-epi-γ-eudesmol and α-eudesmol as main compounds while β-caryophyllene and limonene were the main ones in not polluted area. Ambroxide and ambrial were the most important compounds in the essential oil from C. salvifolius harvested in polluted area while nonanal and tridecanal were the main compounds in control samples. Oxygenated monoterpenes were the most abundant class from both Lavandula stoechas samples, with fenchone and camphor as main compounds.
