The genus Teucrium belongs to the Lamiaceae family. Lamiaceae is one of the important plant groups because most members of this group are used as medicinal and aromatic plants. In this study, the leaves and flowers of Teucrium chamaedrys subsp. chamaedrys and Teucrium polium, which were taken from both their natural habitat and cultivars, were analysed by SPME and GC-MS in two vegetation periods. The amount and the composition of volatile oil of cultivated plants were compared with plants from natural areas. Caryophyllene (12.20-23.74%) was the most abundant component in all samples of Teucrium chamaedrys except in samples from natural habitats of the first vegetation period. Moreover, 2-hexen-1-al (12.79-13.98%), germacrene-D (11.99-19.60%) and α-pinene (3.80-11.68%) were the dominant components of the T. chamaedrys, while in Teucrium polium samples, β-myrcene (19.52-25.28%) was the common component in both sampling area of the first vegetation period, limonene (30.87-31.79%) had the highest amount in the second vegetation period. Besides, α-thujone (3.13-18.87%), α-pinene (0.94-17.93%) and germacrene-D (4.31-15.63%) were detected as major components in samples from both natural habitats and cultivars of T. polium.
