Comparison of antioxidant activity between two sweet pepper genotypes infected with Alternaria alternata

Abstract

The resistance of two sweet pepper varieties (cultivar Anita and breeding line 82/16) to fruit root caused by fungus Alternaria alternata was evaluated. In order to determine the antioxidant capacity of methanol extracts of tested fruits as well as their relation with phenolic compounds three different antioxidant tests were used and the content of total polyphenols and total flavonoids was measured. The results suggested that not only phenolic compounds might be involved in antioxidant activity of pepper fruits, but also carotenoids and vitamins C and E
