| Consumption of Brassica vegetables is related to a decreased incidence of certain cancer forms, and it has been linked to the presence of glucosinolates in these vegetables. After ripe seeds, Brassica sprouts contain the highest concentration of these compounds and are therefore a good source of glucosinolates for chemoprotection. In the present experiments, the content and distribution of glucosinolates in five varieties of B. oleracea (white cabbage, red cabbage, Savoy cabbage, broccoli and cauliflower) was determined in ripe seeds and sprouts of up to seven days by High Performance Liquid Chromatography. The type and concentration of individual glucosinolates varied according to B. oleracea variety, plant part and length of the sprouting period.... |

| Brassicaceous food crops contain in their tissues different quantities of the glucoside allelochemicals known as glucosinolates (Bellostas et al., 2004; Sørensen, 1990). These compounds are alkyl-N-hydroximine sulphate esters with a β-D-thioglucopyranoside group attached to the hydroximine carbon in Z-configuration relative to the sulphate group (Ettlinger and Kjær, 1968; Kjær, 1960). Glucosinolates are biosynthetically derived from amino acids (Hill et al., 2003) and they occur in all plants of the order Capparales and in some other plants (Bjerg and Sørensen, 1987; Kjær, 1960; Rodman, 1978). These compounds co-occur with myrosinase isoenzymes (Thioglucosidase; EC 3.2.1.147), which catalyze the hydrolysis of the β-D-thioglucopyranoside bond releasing an... |
