✦ Synopsis

Essential oils were isolated from dierent parts of Crithmum maritimum L. at three stages of the life cycle (vegetative, ¯owering and fruiting) in the same population (central west Portuguese coast) and essential oils were also extracted from plants growing spontaneously in ®ve parts of the Western coast of Portugal, at the three life cycle stages. GC and GC±MS analyses were carried out in order to determine the oil chemical composition. The major oil components were dillapiol, sabinene, g-terpinene and thymol methyl ether. The higher phenological variations observed were in the components of the in¯orescences essential oils. Gradual variations were found along the life-cycle stages in the oils from the aerial parts. The oil data obtained from the ®ve populations were statistically processed and the results showed the presence of two possible chemotypes of C. maritimum with dierent dillapiol content.
