The article presents a scientific work on the search for the isolation of the sum of flavonoids from young leaves of the walnut family Juglans regia L. from the gardens of the Bostandyk district of the Republic of Uzbekistan. Some physicochemical properties of the isolated flavonoids were studied by qualitative and quantitative methods. In the process of considering various literary sources on the content of flavonoids in nuts, it is known that of all the variety of phenolic compounds, flavonoids prevail in walnuts, which have a wide range of biological action in medicine. Namely, young leaves have medicinal value. The results allow the development to be used for implementation in production in order to increase the effectiveness of drugs.

flavonoids, extract, leaves, walnuts, Juglans regia L., biological activity.
