The influence of the time of distillation on the content and composition of essential oil isolated from wild thyme (Thymus serpyllum L.) by hydrodistillation was investigated. The GC-MS data showed that the essential oil was rich in carvacrol (30.90–46.16%) and its biogenetic precursors γ-terpinene (5.72–9.09%) and p-cymene (4.51–13.46%). Other constituents identified in significant amounts were β-caryophyllene, carvacrol methyl ether and (-)-β-bisabolene. On the basis of the obtained data it was proved that time of distillation had no effect on essential oil content. Moreover, there was no significant effect of the distillation time on the content of essential oil constituents found in the experiment.
