Abstract

Jacobaea is a small genus of plants belonging to Asteraceae family, formerly joint to Senecio genus, that includes more than 60 species and sub-species. Several taxa of this genus have been extensively studied both for their non-volatile and volatile metabolites. In the present study the chemical composition of the essential oil (EO) from aerial parts of Jacobaea delphiniifolia (Vahl) Pelser & Veldkamp, collected in Sicily, was analyzed by GC-MS. No one report has been previously published on the EO of this species. The result showed the presence of a large quantity of two metabolites, namely 1-undecene (63.57%) and thymol methyl ether (13.65%). Chemotaxonomic considerations were carried out by comparing the other oils of Jacobaea taxa studied so far.
