Abstract

Obesity is one of the most common metabolic syndromes and is a major threat to human health worldwide. Given the size of this problem, there is growing interest in natural agents that may decrease obesity. In this study, we investigated the anti-obesity effect of a capsicoside G-rich fraction (CRF; 13.35% capsicoside G) isolated from pepper seeds in diet-induced obese mice. C57BL/6J mice were fed either a normal diet or a high-fat diet (HFD), with or without CRF (HFD + CRF; 10 and 100 mg/kg body weight). The body weight and food efficiency ratio of mice fed HFD + CRF were lower in comparison to that of mice fed only an HFD. Epididymal adipose tissue weight and adipocyte hypertrophy were significantly lower in HFD + CRF mice than in HFD mice. The fat deposition in the liver of mice fed HFD + CRF was lower compared to that of mice fed only an HFD. CRF significantly reversed the HFD-induced elevation of the expression of key adipocyte differentiation regulators, including peroxisome proliferator-activated receptor γ, CCAAT/enhancer-binding protein α, sterol regulatory element binding protein 1c, and their target genes. These results suggest that CRF could be used as dietary therapy for the prevention of obesity and obesity-related metabolic diseases. Copyright © 2016 John Wiley & Sons, Ltd.
