Abstract:

Changes in the contents of glucosinolates, anthocyanins, vitamin C and total phenolics and ferric reducing
antioxidant power (FRAP) value in two radish cultivars known as ‘Fushunhong’ and ‘Shengfengbai’ were investigated
during seed germination. The results showed that individual glucosinolates decreased significantly in two radish cultivars
except for glucoraphasatin in ‘Shengfengbai’. The phenolic contents in 5-day-old sprouts of ‘Fushunhong’ and ‘Shengfengbai’
decreased by 61.62% and 43.93%, respectively, as compared to those of raw seeds. Vitamin C was found to be absent in
seeds but its content increased sharply with the progress of germination, reaching 65.81 and 52.48 mg/100 g, respectively, in
7-day-old sprouts of ‘Fushunhong’ and ‘Shengfengbai’.
