, broccoli, and cauliflower ( Brassica sp.) are rich in essential nutrients. In addition, they contain substantial quantities of the glucoside-aglycone sulforaphane or 4-methylsulfinylbutyl isothiocyanate, which are very potent inducers of detoxication

wavelength treatment ( Table 1 ). The enzyme myrosinase catalyzes the hydrolysis of sinigrin to produce allyl isothiocyanate, which reduces the incident of certain cancers ( Stoewsand, 1995 ). Wavelength did not affect the accumulation of any of the other GS

the potential bioherbicidal effects of Brassica seed meals. Some Brassica seed meals contain nitrogen- and sulfur-containing compounds called glucosinolates (GLS), which can be hydrolyzed into a number of bioactive compounds, including isothiocyanates

vegetables are the glucosinolates (GS) and their hydrolyzed isothiocyanate products. Isothiocyanates are chemopreventive agents demonstrating anticarcinogenic activity in the human diet. Previously, research in our group showed that a 5-d exposure to only
