The aerial parts of Satureja hortensis L. were collected at flowering stage, dried naturally in a drying room and then submitted to distillation in order to obtain the essential oil. Three distillation methods were applied: hydrodistillation in Deryng-type apparatus, hydrodistillation in Clevenger-type apparatus and water-steam distillation. The isolated oils were analyzed by GC-MS. Carvacrol (62.91-72.19 %) and γ-terpinene (17.17-21.37 %) were the dominating components in the all analyzed oil samples. On the basis of the obtained data it was proved that distillation method had no significant effect on the content of the main S. hortensis essential oil components. However, there were statistically significant differences found for interaction between the concentration of the main oil constituents and the method of distillation.
