Inhibitory effect of the ZL and FL Citrus limon extracts on the oxidative DNA damage caused by H₂O₂. Line 1: untreated plasmid; Line 2: plasmid treated with 5 mg/ml ZL extract; Line 3: plasmid treated with 5 mg/ml of FL extract; Line 4: positive control (quercetin (10 mg/ml) + Rf Fenton); Line 5: negative control (plasmid + Rf Fenton).
