The cauliflower, is a very appreciate vegetable crop for its nutritional and nutraceutic properties. In particular it contains glucosinolates that have been reported to prevent some cancer diseases. The aim of this work was to determined profiles of nitrogen and sulphur metabolites of the corimb of cauliflower (Brassica oleracea subp. botrytis cv Atalaya) in plants grown under different farming methods (traditional versus reduced/no work). The analyses were done on the immature flowers and the corimb stem of plants harvested and stored at -80°C. The samples powdered in liquid nitrogen were used to determine the content of protein, carbohydrates, pigments, ascorbate and glutathione, inorganic and organic acids and glucosinolates. The comparative analyses of data evidenced that different distributions of such metabolites occurred in the immature flowers and the corimb stem, but no significant change seemed dependent on the applied farming methods. The work was financed by Seconda Università di Napoli and MIUR (Progetto PRIN 2006077008).

Abstract
The cauliflower, is a very appreciate vegetable crop for its nutritional and nutraceutic properties. In particular it contains glucosinolates that have been reported to prevent some cancer diseases. The aim of this work was to determined profiles of nitrogen and sulphur metabolites of the corimb of cauliflower (Brassica oleracea subp. botrytis cv Atalaya) in plants grown under different farming methods (traditional versus reduced/no work). The analyses were done on the immature flowers and the corimb stem of plants harvested and stored at -80°C. The samples powdered in liquid nitrogen were used to determine the content of protein, carbohydrates, pigments, ascorbate and glutathione, inorganic and organic acids and glucosinolates. The comparative analyses of data evidenced that different distributions of such metabolites occurred in the immature flowers and the corimb stem, but no significant change seemed dependent on the applied farming methods.
