Flavonoids are organic compounds with diverse phenolic structures that possess significant therapeutic potential, including antiviral, anti-inflammatory, and antioxidant activities. This article describes the conditions that ensure the maximum extraction of flavonoids from the leaves of forgotten sweetvetch: 70% ethanol as the extraction solvent, a particle size of 2.5 mm, an extraction time of 40–50 minutes, and a raw material-to-solvent ratio of 1:100. The optimal conditions for the complexation reaction between flavonoids from forgotten sweetvetch leaves and aluminum chloride were also determined, including the extract₃ volume ratio (1:1) and the appropriate stabilizer.
