So, the main object of the work was to study the function of horticultural crops enriched with antioxidants as a possible alternative opportunity in combating covid-19. Natural antioxidants such as vitamins, bioactive molecules, various polyphenols and some of micro nutrients have promising abilities for being used as antiviral agents. This promising feature is accompanied with its effect on decreasing the levels of ROS in infected cells, inhibiting replication of several strains of different viruses and prevention of proliferation of cancer cells. Results highlighted the anti-viral effects of different antioxidants which can be summarized in three groups; 1) polyphenols with anti-inflammatory and anti-allergy effect 2) vitamins with inhibitory effect on oxidation processes, preserves the epithelium, improves immune function in the elderly and 3) minerals with the formation of antibody and improve immune system. According to these comprehensive results of review, antioxidants propose promising goals for improving oxygenation rates and glutathione levels, decreasing sodium intake and blood pressure, strengthens immune response and prevention of chronic human diseases.
