COMPARATIVE PHARMACOGNOSTIC STUDY OF TWO CHEMOTYPS THYMUS SERPYLLUM L. OF CENTRAL KAZAKHSTAN
The article presents the results of a comparative pharmacognostic study of two samples of the herb Thymus serpyllum L.s.l. collected in the territory of Central Kazakhstan. The results of the research allowed to determine that the Thymus serpyllum L.s.l. growing in the Karaganda region is represented by two chemotypes that have an external similarity, however, there are slight differences related to the environment and growing conditions. In two samples of Thymus serpyllum L.s.l. identical diagnostic features of the anatomical structure for the leaf, stem, calyx and corolla were determined. At the same time, there are significant differences between the two chemotypes of Thymus serpyllum L.s.l. in yield and component composition of the essential oil, as well as in the quantitative content of flavonoids, phenol carboxylic acids, tannins, triterpene compounds, watersoluble polysaccharides, pectic substances, amino acids and organic acids.
