Aerial parts of Artemisia arborescens were collected from different sites of the Mediterranean area (southwestern Algeria and southern Italy) and the chemical composition of their essential oil ( EO ) extracted by hydrodistillation was studied by both gas chromatography ( GC ) equipped with an enantioselective capillary column and GC /mass spectrometry ( GC / MS ). The EO s obtained were tested against several Listeria monocytogenes strains. Using GC and GC / MS , 41 compounds were identified, accounting for 96.0 – 98.8% of the total EO . All EO s showed a similar terpene profile, which was rich in chamazulene, β ‐thujone, and camphor. However, the concentration of such compounds varied among the EO s. A . arborescens EO inhibited up to 83.3% of the L . monocytogenes strains, but the inhibitory spectrum varied among the EO s, with those from Algeria showing a higher inhibition degree than the Italian EO s. Such effect likely depended on the ketone ( β ‐thujone + camphor) content of the EO . The differences in the EO composition support the hypothesis that A . arborescens has at least two different chemotypes: a β ‐thujone and a chamazulene type. The EO inhibitory spectrum indicates the A . arborescens EO as a valuable option in the control of the food‐borne pathogens.
