Abstract :
This study aimed to appraise the chemical features such as total phenol (TP), total flavonoid (TF), and total
antioxidant capacity based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power
(FRAP) assays of bran and grain in 10 genotypes of rice (Oryza sativa L.) grown in Iran. Based on two
procedures of DPPH and FRAP, the results demonstrated that in terms of the amount of antioxidants in the
bran of genotypes of the tested rice, genotype G4 achieved the highest and genotype G6 achieved the lowest
mean. Also, the examination of the amount of the antioxidant in genotypes grain of the tested rice showed
that genotype G4 had the highest and genotype G6 had the lowest mean in the antioxidant of the grain.
Besides, the examination of phenol and flavonoid levels of grain and the bran of the tested genotypes
indicated that genotype G3 had the highest TP level and the genotype G4 had the highest flavonoid level in
this experiment and they were placed in group A in the mean comparison table. The correlation result
between phenolic compounds and antioxidant procedures confirmed that there are significant correlations
among traits in this study.
