Abstract:The antioxidation capacities and relationship of 14 various colors peanut were investigated in this manuscript through examining the active oxygen resistance reactivity units(AORRU),superoxide anion resistance reactivity units(SARRU),total antioxidant reactivity units(TARU),flavonoid compounds,Vc contents,protein contents and pigments concentrations.Significantly differences were observed in the peanut varieties and in different parts of same peanut kernel.The main results were achieved:(1)There were genotype differences in flavonoid compounds,Vc contents,protein contents and pigments concentrations of peanut kernel;(2) the highest flavonoid compounds and Vc contents in seed coats;(3)highest free amino acids content in embryo;(4) the pigments concentrations in seed coat of white peanut was not the lowest.Furthermore,the results demonstrated that the antioxidation capacities of peanut were significantly positive related to the total free amino acids content and the flavonoid compounds,but the protein content shown negative role on the antioxidation capacities and the flavonoid compounds.
