The aim of this study was to investigate the amounts of glucosinolates (GSL) in kale at various development stages. Kale varieties Manchoo Collard and TBC were cultivated from 20 February 2012 to 3 July 2013 in the greenhouse at Chungnam National University. During the cultivation periods, samples were harvested at 35, 63, 91, 105, 119, and 133 days after sowing (DAS) and the amount of GSL quantified by HPLC. Ten types of GSL (progoitrin, sinigrin, glucoalyssin, gluconapin, glucoiberverin, 4-hydroxyglucobrassicin, glucobrassicin, 4-methoxyglucobrassicin, gluconasturtiin, and neoglucobrassicin) were observed in TBC, whereas nine types of GSL (the same as above, except glucoiberverin) were identified in Manchoo Collard.
