Properties of essential oils can be changed, depend- ing on their origin and composition. Thus, the chemical composition of thyme essential oil used in the current research has been investigated and the results are shown in Figures 1 and 2.
According to the results of the chemical analysis of thyme essential oil, 25 compounds were identified, which represented 94.53% of the oil content. It can be noted that the highest percentage of compounds includes three classes: monoterpene hydrocarbons, aromatic hydrocarbons and oxidized monoterpenes. Other groups of compounds are present in less than 1% (Figs. 1 and 2). More than half of total compounds of thyme essential oil include 6 dominant compounds. Among them, the most dominant is the oxidized mono- terpene thymol (36.12%) and the monoterpene hydro- carbon p-cymene (21.15%). Other dominant compo- nents of this essential oil are the following: γ-terpinene
