Abstract

Using highly efficient liquid chromatography, the presence of substances of a flavonoid nature in industrial hemp was established. During the performance of high performance liquid chromatography, the dominant substance was isolated, which was identified as quercetin (3, 3', 4', 5,7 - pentahydroxyflavone). The technique of quantitative determination of the amount of flavonoids in the leaves of industrial hemp was used. The content of flavonoids in hemp leaves has been determined. Thus, industrial hemp is a promising medicinal raw material in terms of creating flavonoid preparations.
