In this study, the concentrations of four flavonols (morin, myrycetin, quercetin and kaempferol) were determined in radish and alfalfa sprouts. Sprouts were germinated in total darkness and various temperatures (4°C, 20°C, 30°C) and light conditions (UV, IR) According to germination conditions, different amounts of flavonols in sprouts were observed. Total content of flavonols varies within 55.39-216.20 μg·g−1 and 382.16-721.05 μg·g−1 dry weight for radish and alfalfa sprouts, respectively. A highest concentration of flavonols was determined in sprouts germinated in darkness and 20°C. The results indicated that alfalfa sprouts are a rich source of kaempferol − 580 μg in 1g of lyophilized product.
