Abstract

Tomatoes are one of the most widely consumed vegetables in the Mediterranean Diet. They are a rich source of antioxidant compounds and their consumption is linked with a reduction of various types of pathologies. In addition to geographical and seasonal variables, cultivar is an important factor affecting the profile and the concentration of antioxidant compounds. “Pomodorino Vesuviano” is a Protected Designation of Origin (PDO) tomato cultivar traditionally grown in Campania (southern Italy), which to the best of our knowledge has never been analyzed for bioactive compounds before. Here we present a study conducted to investigate the carotenoid and flavonoid content in tomatoes from this cultivar. Results indicate that Pomodorino Vesuviano is a rich source of antioxidants, with lycopene (78.6 mg/kg fresh weight (fw)) and quercetin (8.52 mg/kg fw) are the major components. Moreover, cell-based studies have suggested that a synergistic effect among phytochemicals in tomatoes is responsible for their antioxidant activity, since the combination of low concentrations of carotenoids and polyphenols (i.e. per se inactive concentrations) resulted in a significant reduction of reactive oxygen species (ROS) formation.
