Savory essential oil contained 0.5-1.7% of each of the following monoterpene hydrocarbons: a-thujene, a-pinene, camphene, P-pinene, P-myrcene, sabinene, a-phellandrene, a-terpinene, and 4.2% sesquiterpene hydrocarbon—P-caryophyllene. The content of y-terpinene was 10.5%. This essential oil contained two isomeric phenols—thymol (17.5%) and carvacrol (35.2%). A high content of thymol, carvacrol, and y-terpinene was respondent for the antioxidant properties of the savory oil [15, 16]. It was revealed earlier that the addition of thyme oil (1200 mg per 1 kg of mass) into rat feed increased the general antioxidant status of the animals and kept a high level of polyunsaturated fatty acids in cell membranes during the process of their ageing [17]. Thyme and savory essential oils have a close content of the main components, both essential oils showed the same antiradical properties. As can be seen in Table 10.1, the values of antiradical efficiencies AE are close for two oils [15]. That is why we hoped that the oil of savory, which is successfully grown in central Russia, would also possess biological activity. It should be noted that savory oil doses in our work were by a factor of 100 lower than in the study by Youdim and Deans [17].

The essential oil of Teucrium polium L. (TP-EO) was extracted from the aerial parts of plants collected at the flowering phase. The sample was collected from plants growing in North West Riyadh (Kingdom of Saudi Arabia). The plant was identified as Teucrium polium L. by Migahid.[33] The sample was shade-dried at room temperature (20-25 °C) for 10 days. Thereafter, 150 g of the dried aerial parts was ground and immersed in 1 L of distilled water. The TP-EO was obtained with hydro-distillation method at 60 °C for 4 h using Clevenger-type apparatus technique. Then, the essential oil was collected over anhydrous sodium sulfate and kept in a closed vial prior to further experiments. According to study by Guetata and Al-Ghamdi,[19] the predominant constituents of the essential oil (TP-EO) extracted aerial parts Teucrium polium L in Saudi Arabia were γ-Muurolene (8.72%), δ-cadinene (5.08%), γ-cadinene (2.81%) α-cadinol (5.93%) spathulenol (3.42%), caryophyllene oxide (1.22%), β-pinene (4.58%), α- limonene (4.29%), α- pinene (3.7%), p-cymene (2.91), sabinene (2.74), 4-terpinol (3.72%), cis-bisabolene (1.54%), linalool (1.18%), and α-thujene (3.69%).
