Creeping thyme (Thymus serpillum L.) is mostly used as a medicinal plant in the Russian Federation. It has much more winter hardiness then common thyme (Thymus vulgaris L.), which is similarly used in Europe. However, T. vulgaris is interesting as a plant in food industry and in medicine. T. vulgaris contains two to three times more essential oil (2 %) than T. serpillum L. and a higher сontent of thymol in its essential oil (up to 35-40 % depending on the genotype). The objectives of the present study are to determine the total essential oil content, the total polyphenol content, the total flavonoid content and the yield from 8 varieties of thyme during two years. We found that the ‘Colchida’ and ‘Lemon’ varieties are characterized by high yields. The maximum amounts of essential oil were found in ‘Deutscher Winter’ (1.3 %), ‘Médoc’ and ‘Lemon’ (1.19 %), flavonoids content in plants was 1.27-2.87 %. Our studies have shown that T. vulgaris can be considered as a potential medicinal and aromatic plant for growing in the non-chernozem zone of the Russian Federation.
