Evaluation of total phenolics, flavonoids and antioxidant activity of 18 Korean onion cultivars: a comparative study

Abstract

Among the 18 cultivars, Sunpower is the most promising in terms of total phenolics, total flavonoids and antioxidant activity. Our results suggest that day length sensitivity/ripening among the cultivars do not play any significant role for high values of total phenolics, flavonoids and antioxidant activity.
