국문 초록

Black soybeans are valued for their rich nutritional content and potential health benefits, attributed to their functional components that enhance antioxidant activity. In this study, we evaluate and compare the isoflavone and anthocyanin content, as well as the antioxidant potential, of seven Korean black soybean genotypes. Isoflavone content ranged from 2,032.8 to 3,536.8 μg/g, with Soman displaying the highest levels of both aglycones and glucosides, indicating notable bioactive potential. In terms of anthocyanins, Danheuk had the highest total content (24,080.6 μg/g), while Soman excelled in Pelargonidin-3- glucoside (Pg3glc). Soman also showed superior antioxidant activity across all measures, including total polyphenol, flavonoid content, as well as radical scavenging abilities (ABTS and DPPH). Strong correlations were found between total flavonoid content, total polyphenol content, genistin, total isoflavone content and antioxidant activity, while correlations with total anthocyanins were relatively weaker. These findings reveal significant genetic variability in isoflavone and anthocyanin content among soybean genotypes, with Soman showing particularly high antioxidant potential, suggesting its value for health-related applications and soybean breeding programs.
