Evaluation of Antioxidant Properties, Total Phenolic Content, and Biological Activities of New Tomato Hybrids of Industrial Interest

Abstract The objective of the present work was to establish the antioxidative ability linked to lipophilic, hydrophilic, and polyphenolic fractions of new tomato hybrids of industrial interest, grown in an outdoor field, named “Medugno”, situated in the Agro-Nocerino Sarnese area (Province of Salerno, Campania Region, Italy). Antioxidant activities of lipophilic, hydrophilic, and polyphenolic extracts of tomato hybrids determined by the 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid), N,N-dimethyl-p-phenylenediamine dihydrochloride, and 2,2-diphenyl-1-picrylhydrazyl methods, respectively, showed the best results in hybrids obtained between the pure San Marzano and Black Tomato lines. Antioxidant activity tests, performed also on the San Marzano×Black Tomato hybrid (pulped tomatoes), indicated that the industrial transformation process of this new tomato hybrid did not cause a significant loss of antioxidant activity. The in vitro production of nitrite by lipopolysaccharide-stimulated macrophages J77...
