THE STUDY OF PHENOLIC COMPOUNDS OF THREE TYPES OF THE GENUS TANACETUM L. IN THE CONDITIONS OF THE BASHKIR CISURALS

Essential oil plants of the genus Tanacetum L. (Asteraceae) contain a rich set of biologically active substances (essential oils, flavonoids, hydroxycinnamic acids, tannins, vitamins, organic acids, etc.) with a wide range of pharmacological activity – anti-inflammatory, choleretic, anthelmintic, antibacterial, antioxidant. Recently, new types of biological activity of plants of the genus Tanacetum have been identified, which makes it relevant to study closely related species as additional sources of medicinal plant raw materials. The purpose of this work is a comparative study of the qualitative composition and quantitative content of some phenolic compounds of three species of the genus Tanacetum L. – T. vulgare, T. balsamita and T. balsamitoides. The flowers of the studied samples were used for analysis: T. vulgare, a wild species harvested in the Ufa region of the Republic of Bashkortostan, as well as flowers of two species (T. balsamita and T. balsamitoides) cultivated in the South Ural Botanical Garden-Institute of the UFIC RAS. As a result of the study, it was found that samples of the wild species T. vulgare contain a higher amount of flavonoids (2.70±0.10%) and hydroxycinnamic acids (3.05±0.12%), but poorly studied closely related species T. balsamita and T. balsamitoides are slightly inferior in the content of flavonoids (2.53±0.12 and 2.14±0.09%) and hydroxycinnamic acids (2.74±0.11 and 2.38±0.08%) to the pharmacopoeial species - T. vulgare, therefore they are promising for further study as potential sources of valuable biologically active substances and for expanding the raw material base of medicinal plant raw materials.
