Phytochemical Analysis of Biotechnological Raw Materials of Representatives of the Genus Potentilla L.

Аннотация

The genus Potentilla (Potentilla L.) is a member of the family Rosaceae, widespread in temperate, arctic, and alpine zones of the northern hemisphere. This genus has been known since ancient times for its curative properties. Recent pharmacological studies have confirmed the traditional use of extracts of the Potentilla species against different diseases. The phytochemistry of the members of Potentilla L. remains poorly studied. A biotechnological technique for the production of renewable raw materials has been developed only for Potentilla alba L. The goal of this work is to conduct the phytochemical analysis of biotechnological raw materials of Potentilla alba L. and Potentilla fragarioides L. and to identify the features of the elemental composition and accumulation of biologically active substances in regenerants, compared to the intact plants. The research has led to the development of a biotechnological technique for the production of P. fragarioides phytomass. The intensity and the specificity of accumulation of chemical elements by organs of regenerated plants of P. alba from the nutrient media in tissue culture have been evaluated. The elements of vigorous accumulation (Ca, Mg, Fe, Mn, Zn, Mo, and Cu), as well as the element of strong accumulation, Co, are noted. The features of the elemental composition of P. alba raw materials, depending on the production method, are noted. The quality, the content of water- and alcohol-soluble extractives and of some groups of biologically active substances have been estimated. It is revealed that P. alba and P. fragarioides are concentrators of flavonoids and tannins. At the same time, the indicators of accumulation of biologically active substances in P. fragarioides are higher than those for P. alba, in both conventional and biotechnological plant raw materials.
