The essential oil extracted from Carduncellus helenioides was analyzed using GC/EIMS. It was characterized by diepicedrene-1-oxide (10.6%), isoaromadendrene epoxide (7.1 %), caryophyllene oxide (6.20 %) , eudesmol (6.17 %) and aromadendrene oxide (1.3 %) as major constituents. The antibacterial activity of the essential oil of this plant were carrying out by disc diffusion method against four bacterial strains and the oil was only active against Staphylococcus aureus ATCC 25923.
