Abstract The composition of the essential oils of the aerial parts of Teucrium creticum L. (Lamiaceae) from Cyprus was determined by GC and GC/MS. A total of 34 components were identified. The major constituents of the flower and leaf oils were linalool (23.1%), β-caryophyllene (13.3%) and caryophyllene oxide (11.3%), while β-caryophyllene (22.0%), caryophyllene oxide (157%), spathulenol (l4.2%) and linalool (10.6%) were the major components of the flower, fruit and leaf oils. The major constituents of the flower oil were β-caryophyllene (21.5%), followed by caryophyllene oxide (13â8%), Linalool (12.0%), germacrene D (10.8%) and spathulenol (8.6%) while an α-bisabolol oxide (l6.7%), caryophyllene oxide, β-bourbonene (9â9%) and linalool (8.1%) were major components of the stem oil.
