| 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 μol/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. |
