Thiobarbituric acid reactive species (TBARS) production in the reaction mixtures of the deoxyribose degradation assay: (a) H₂O₂/Fe(III)EDTA/ascorbic acid (1 h incubation); (b) H₂O₂/Fe(III)EDTA (1 h incubation); (c) Fe(III)EDTA/ascorbic acid (16 h incubation); and (d) Fe(III)EDTA (16 h incubation) (100% = TBARS of the control reaction mixture of the assay variant H₂O₂/Fe(III)EDTA/ascorbic acid). Error bars show standard deviation (SD) of three replicates; letters (a–h) indicate levels of significance (95% Duncan); EDTA = ethylenediaminetetraacetic acid.
