The article presents the results of a study of the physico-chemical composition, antioxidant activity, vitamin and mineral composition of wild raw materials of Northern Kazakhstan (sweet clover, St. John's wort and purslane). It has been established that this vegetable raw material contains a significant amount of bioactive compounds - polyphenols, vitamins and minerals. Polyphenols, β-carotene have antioxidant, immune-restoring properties. The article also presents the results of an assessment of the chemical composition, including the content of secondary metabolites, quality and safety indicators of the initial plant raw materials. The article contains the results of studying the biological activity of the aboveground parts of sweet clover, St. John's wort and purslane, and the prospects for using the selected plant raw materials for the extraction of secondary metabolites with a wide range of biological activity are established. These studies open up new opportunities for the use of native plants in the food industry. The expediency of using these plants as sources of natural antioxidants and biologically active additives to improve human health is substantiated. The possibilities of integrating these plants into formulations of food additives and functional products to improve the overall condition of the body are also considered. The use of biologically active substances of plants of Northern Kazakhstan in the food industry opens up new opportunities for the development of the region and the expansion of the range of functional nutrition.
