Quercetin decreased high-fat diet induced serum lipid levels and hepatic lipid accumulation. a Serum lipid fractions are shown as ratio of quercetin fed mice (n = 11) over the average value of the control mice (n = 12). Two-way ANOVA; diet significant (p < 0.01). b Representative pictures of hepatic lipid staining with Oil red O for control and quercetin fed mice on a high-fat diet (n = 6). Quantification of mean total area of lipids per picture (c) and mean lipid droplet number per picture (d). Data are presented as mean ± SEM. White bars indicate the control group (C) and black bars indicate the quercetin group (Q). Asterisks indicate a significant difference between both groups, *p < 0.05, **p < 0.01.
