To the biochemistry of some representatives of the genus Thymus L. under the culture

Representatives of the genus Thymus (thyme) are widely used in folk medicine as anti-inflammatory, expectorant, antibacterial agents. However, two species of thyme are pharmacopeial and approved for use in scientific medicine: T. serpyllium L. and T. vulgaris L., therefore, the study of other species is promising for expanding the resource potential of representatives of this genus. The research provides the results of studying the chemical composition and some commodity quality indicators of raw materials (humidity and total ash) of four taxa of the genus Thymus: T. serpyllum L., T. marschallianus Willd., T. pseudonummularius Klokov & Des.-Shost., T. caucasicus Willd. ex Benth., which have been cultivated for more than 20 years in the South-Ural Botanical Garden-Institute of the UFRC RAS in the collection "Aromatic Garden". It has been established that the commodity quality indicators of the raw materials of the studied thyme samples meet the requirements of the pharmacopeial monograph (GM 1.5.3.0007.15). Analysis of the chemical composition of the studied thyme samples has shown that they contain biologically active substances important for spicy-aromatic plants - essential oils (0.88–1.37 %), tannins (8.15–12.48 %), ascorbic acid (0.069–0.102 %), organic acids (2.19–3.58 %), flavonoids (1.73–2.38 %). The leading position in all indicators of the conducted chemical analysis is occupied by T. marschallianus, which is superior to the pharmacopeial species (T. serpyllum) and can be recommended as an alternative source of raw materials for expanding the raw material base and further studying this species from other regions of the Russian Federation according to the indicators of the type sections of the pharmacopeial article "Identification" and "Tests."
