Antioxidative potential of spelt, common buckwheat and tartary buckwheat bran

Abstract

Species as spelt, common buckwheat and tartary buckwheat contain antioxidants and some other substances, which are important for maintaining human health. In our research we tried to determine which and how many antioxidants contained bran and which species of plants contained the the highest quantity of antioxidants. We determined the amount of antioxidants in samples spectrophotometrically. We found out that bran of tartary buckwheat contained the the highest quantity of antioxidants. Total antioxidant activity of tartary buckwheat was 87.23 % DPPH discoloration, followed by common buckwheat with 11.71 % DPPH discoloration, and the lowest total antioxidant activity was found in spelt (1.01 % DPPH discoloration).
