The roots of the common burdock are used in medical and pharmaceutical practice mainly in the form of aqueous extracts, and pharmacological effect is due to water-soluble compounds based on polysaccharides, which causes research interest in identifying the features of the accumulation of this group of compounds.
The purpose of the study is to study the features of the accumulation of biologically active substances in the roots of ordinary burdock, prepared in various agricultural and urbobiogeocenoses of the Voronezh region. As part of the study, 51 samples of the roots of the common burdock we determined the content of the sum of polysaccharides in terms of fructose, gravimetrically precipitated water-soluble polysaccharides and extractive substances extracted by water. In terms of the content of extractive substances extracted by water, 8 samples of the roots of ordinary burdock do not meet the requirements of regulatory documentation. The amount of substances extracted by water was reduced in samples harvested on agricultural land in the Gribanovsky, Repyevsky, Ertilsky districts, under high-voltage power lines, near the chemical enterprises of Minudobrenia OJSC, Voronezh Sintezkauchuk OJSC, along the М4 route in the Ramonsky district, at a distance of 100 m from the А144 route in the Anninsky district The correlation between the accumulation in the studied samples of the sum of polysaccharides in terms of fructose and the sum of gravimetrically determined water-soluble polysaccharides is characterized by a coefficient of 0.42, which indicates a positive moderate relationship. The correlation coefficient between the numerical values of the sum of polysaccharides in terms of fructose and the sum of extractive substances extracted by water from the roots of ordinary burdock was 0.45, which also indicates a moderate positive relationship. A strong positive correlation was established for numerical values of the content in the roots of the common burdock of the sum of gravimetrically determined water-soluble polysaccharides and the sum of extractive substances extracted by water.
