Exploring Sicilian accession of (L.) L.: chemical composition of flower and root's essential oils.

L. (Apiaceae) is a genus distributed worldwide, with the Mediterranean area serving as the centre of its diversity. (L.) L. is an annual plant growing primarily in the temperate biome. For the first time, in this research the chemical composition of the essential oil (EO) from flowers and roots of a Sicilian accession of this plant, was evaluated by GC-MS. An update of all the EOs of the species was carried out and compared to these data the volatile profile of the EO obtained from the Sicilian accessions of is rather particular. Flower and root EOs ( and , respectively) showed alkanes as the main class, accounting for 27.2% and 60.0%, respectively. Both EOs were also characterised by the presence of alloaromadendrene oxide (15.6% in and 11.5% in ). also showed a good amount of sabinene (11.6%), which is totally absent in .
