Biomorphological and biochemical characteristic of Phl'omis tuberosa (Lamiaceae) plants in culture in the taiga middle subzone in Komi Republic

Results of primary introduction studying of Phlómis tuberosa herb in the taiga middle subzone in Komi Republic are given. It is established that Phlómis tuberose plants enter the generative period for the third year of life, then regularly blossom and fructify. On average in 106 days of vegetation they annually form fullfledged seeds, but they do not multiply themselves by self-seeding. In the conditions of the North the chemical composition of Phlómis tuberosa essential oil emitted with a hydrodistillation method from the fresh elevated phytomass of perennial plants is investigated. An exit of essential oil makes 0,32% in terms of absolutely dry raw materials. In component composition of oil 38 compounds are authentically identified, 21 of which are the main. The dominating components are: thymol, ethyl nerolate, trans-α-bergamotene, tricosan, carvacrol, hexahydrofarnesyl acetate, heptacosan, α-caryophyllene, bornylacetate, humulen. It is revealed that Phlómis tuberose plants can successfully be cultivated in the taiga middle subzone as a herb.
