Quercetin protects against cardiac oxidative stress induced by high-cholesterol diet. (a) TBARS and (b) 8-isoprostane were measured in the heart from 12 h fasting rats fed for 4 weeks with control diet (C), control diet containing 0.5% quercetin diet (CQ), high-cholesterol diet (HC), and high-cholesterol diet containing 0.5% quercetin (HCQ). Values are expressed as mean ± SEM. N = 6–8 rats/group. Two-way ANOVA test and Bonferroni posttest. Statistical differences: ^∗ p < 0.05, ^∗∗ p < 0.01, ^∗∗∗ p < 0.001, and ^∗∗∗∗ p < 0.0001.
