                  Satureja montana L., commonly known as winter savory or mountain savory, belongs to
            the Lamiaceae family. It is a perennial semishrub (20–30 cm) that inhabits arid, sunny, and
            rocky regions. The purpose of our study was to determine volatile compounds of S. montana

            aerial parts cultivated in Plodove (Ukraine).
                  The volatile compounds of  S.  montana  aerial parts were identified by comparing the
            mass spectra data with spectrometer database of the NIST 11 Library and by comparison of
            their retention index calculated against n-alkanes (C9–C20). Each chromatographic analysis
            was repeated three times. The average value of the relative composition of the essential oil
            percentage was calculated from the peak areas.  The Hewlett Packard  HP 6890 series GC
            system chromatograph was used for the study, which was coupled with the Hewlett Packard
            5973 mass selective detector (Hewlett Packard, Waldbronn, Germany). The chromatograph
            was equipped with the non-polar, high-temperature ZB-5HT (5 % diphenyl, 95 %
            dimethylpolysiloxane) capillary column; length, 30 m; inner diameter, 0.32 mm; film
            thickness, 0.25  μm (Phenomenex Inc., Torrance, CA,  USA). The gas chromatograph was
            equipped with a split injector; the split ratio was 20:1 and 1 μm of a sample was introduced.
            Helium served as the carrier gas, and its flow rate was 2 mL/min. Analyses were performed at
            a temperature of 40–280 °C and the heating rate was 10°C/min. Injector temperature was 250
            °C.
                  According to the published data, essential oil of S. montana consists mainly of carvacrol
            (0.1–53.35 %),  p-cymene (0.66–41.4 %), thymol (0.15–46.0 %), linalool (0.1–50.42 %), and
            other monoterpenoids, as well as sesquiterpenes and diterpenes. Based on an analysis of the
            chemical composition of the  S.  montana essential oil, currently, some chemotypes are
            identified. Among them are chemotype of thymol and carvacrol, chemotype of linalool,
            p-cymene, and  α-terpineol, chemotype of linalool, intermediate chemotype of
            p-cymene/linalool, chemotype of p-cymene, thymol and carvacrol, chemotype of myrcene and
            viridiflorol.
                  Based on the experimental studies conducted, the authors established the presence of a
            special chemotype of  S.  montana  grown on experimental plots in the Kherson region.
            p-Thymol was dominated (about 81.79 %) in its essential oil. In general, 34 compounds were
            identified. p-Thymol has not been stated earlier in the available scientific publications as the
            dominant component of the S. montana essential oil. Among minor components was linalool
            2.09 %, o-cymene 1.26 %, cis-β-terpineol 1.21 %, terprinen-4-ol 1.07 %, thymol 0.65 %,
            carvacrol 0.05 %. According to literature data, essential oils in which such aromatic
            substances as carvacrol, eugenol or thymol dominate have a pronounced antimicrobial action.
            Hajdari et al. (2016) stated the absence of  carvacrol in the myrcene and viridiflorol
            chemotype and linalool chemotype. These chemotypes contained also minor amounts of
            thymol (0.15–0.79 %).
                  As a result of the performed studies, the new chemotype of S. montana was identified.
