Abstract

Dietary fat is one of the most important environmental factors associated with the incidence of cardiovascular diseases. In this study, the antiobesity effects of rutin (R) and o-coumaric acid (oCA) were investigated. Wistar rats were divided into normal and obese groups, and obese rats were prefed a high-fat diet (HFD) containing 40% beef tallow for 4 weeks. Then, R and oCA were given as a supplement to obese rats at doses of 50 and 100 mg/kg, respectively, for a period of 8 weeks. The results showed that body, liver organ, and adipose tissue weights of peritoneal and epididymal fat pads in the HFD+ R and HFD+oCA groups were significantly decreased as compared to those in the HFD group. Serum lipid profiles, insulin, and leptin were significantly decreased in the HFD+ R (high dose, HD) and HFD+oCA (HD) groups as compared to those in the HFD group. Hepatic triacylglycerol and cholesterol levels were significantly decreased in the HFD+ R (HD) and HFD+oCA (HD) groups as compared to those in the HFD group. Moreover, the consumption of R and oCA reduced oxidative stress and glutathione disulfide (GSSG) content, and enhanced the levels of glutathione (GSH), GSH peroxidase (GPx), GSH reductase (GRd), and GSH S-transferase (GST) in the hepatic tissue of rats with HFD-induced obesity. These results demonstrate that intake of R and oCA can be beneficial for the suppression of high-fat-diet-induced dyslipidemia, hepatosteatosis, and oxidative stress in rats.
