Some biochemical characteristics of species of the genus Monarda

Abstract

The paper presents a comparative study of the content and composition of biologically active substances of the aboveground parts of plants of some Monarda species cultivated in the Botanical Garden, Ural Branch of Russian Academy of Sciences, Ekaterinburg. The greatest quantity of flavones, tannins were found in M. citriodora Cerv. ex Lag., carotenoids, pectins, saponins in M. fistulosa L., pectins in M. didyma L., protopectins in M. media Will. The component composition of the phenolic complex of the samples was studied by high-performance liquid chromatography on an analytical HPLC-system Agilent 1200. 70% ethanol extracts of plants of Monarda species contained at least 35 compounds of phenolic nature, including flavones luteolin, luteolin 7-glucoside, chlorogenic acid.
