Description
Summary:The article presents the results of studying the chemical composition of the leaves of blue honeysuckle, naturally growing in the southern taiga of the Krasnoyarsk Territory. It was found that along with fiber and lignin, the studied biomass contains a significant amount (about 70 wt. %) of extractive substances. Using fractional extraction with solvents of increasing polarity, it was possible to extract from the studied raw materials 9.5 wt.% of substances soluble in non-polar solvents and about 60 wt.% of compounds soluble in isopropanol and water. A spectrophotometric study showed the presence in the leaves of blue honeysuckle (Lonicera caerulea L.) such classes of biologically active compounds that provide a wide range of pharmacological action of the plant, such as chlorophyll-containing derivatives, a complex of bioflavonoids, carbohydrate components, anthocyanins, tannins, organic acids and others. This circumstance opens up broad prospects for the practical usage of the biomass under study in the production of food additives, pharmaceutical and perfumery and cosmetic preparations.
