Biosynthesis and Accumulation of Sulphur Compounds in White Radish During the First Three Days of Sprouting

Abstract

Glucosinolates (GLs) and S-methyl cysteine sulfoxide (SMCSO) are natural sulphur containing phytochemicals. They are two of the most important bioactive compounds found in brassica vegetables, which are highly regarded for their health-promoting activity. In this study we have analysed the content of GLs and SMCSO in white radish, by an HPLC-MS method, in order to illustrate their biosynthesis and accumulation during the first 72 hours of sprouting. Total GLs content ranged between 54.17 and 126.86 µmol/g DW. There were eight GLs identified, in radish sprouts and around 94 % of them were aliphatic. Obvious differences, during the 72 hours of sprouting, were noticed in glucoraphenin and glucoraphasatin. S-methyl cysteine sulfoxide content ranged between 0.21 and 35.95 µmol/g DW. Our results revealed a negative strong correlation between GLs and SMCSO.
