Abstract: Glucosinolates, anthocyanins, total phenols, and vitamin C, as well as antioxidant capacity, were investigated in Chinese kale sprouts treated with both glucose and gibberellic acid (GA₃). The combination of 3% (0.03 g/ml) glucose and 5 μmol/L GA₃ treatment was effective in increasing glucosinolate content while glucose or GA₃ treatment alone did not influence significantly almost all individual glucosinolates or total glucosinolates. The total phenolic content and antioxidant activity of Chinese kale sprouts were enhanced by combined treatment with glucose and GA₃, which could be useful in improving the main health-promoting compounds and antioxidant activity in Chinese kale sprouts.

Key words: Glucosinolate; Antioxidant; Glucose; Gibberellic acid; Chinese kale sprouts
