GC-MS analysis of the isolated oils revealed that carvacrol (42.81–45.24%), γ-terpinene (7.68–9.04%), β-caryophyllene (5.28-9.10%), β-bisabolene (5.76–6.91%) and carvacrol methyl ether (4.92–6.09%) were the major components of all the samples.On the basis of the obtained data it was proved that the type of distillation apparatus had no significant effect on the content of the main essential oil constituents of wild thyme. However, based on the means for both years of the study it was proved that hydrodistil-lation in Deryng apparatus was more effective for carvacrol concentration, while in Clev-enger apparatus – for γ-terpinene and carvacrol methyl ether concentration. The type of distillation apparatus had no significant effect on the content of the other essential oil constituents.Key words: wild thyme, hydrodistillation, essential oil composition, carvacrol, γ-terpinene, β-caryophyllene
