The chemical composition of the volatile metabolites of Crithmum
maritimum harvested from several geographic localities along the
Mediterranean coasts was studied by GC and GC-MSD.The
major oil
constituents were found to be dillapiole, gamma-terpinene, sabinene,
limonene and beta-phellandrene.The Western populations were richer
in dillapiole,whereas the Southern collections were characterized by
increased amounts of thymol methyl ether and gamma-terpinene. The
Italian chemical profiles differentiated by the significant contributions of
carvacrol methyl ether and isoterpinolene.The essential oils were also
investigated for their insecticidal activity and their repellency against
Pheidole pallidula (Nylander)ants and found to possess significant
activity.
