Tangeretin and heptamethoxyflavone were investigated for their ability to repair metabolic damage caused by high-fat diet in C57BL/6J mice. In the first four weeks, induction of obesity was performed and the mice received standard diet (11% kcal from fat) or high-fat diet (45% kcal from fat). After that, in the next four weeks, two groups received supplements (tangeretin or heptamethoxyflavone – dose of 100mg/kg) into the high-fat diet, and the other groups continued to receive their respective diets. Tangeretin and heptamethoxyflavone decreased blood serum levels of glucose, leptin and resistin and the HOMA-IR index. Besides that, blood serum TBARS levels were lower in supplemented groups than in non-supplemented. In addition, tangeretin reduced adipocyte size, and heptamethoxyflavone decreased fat accumulation in the liver. The results show that tangeretin and heptamethoxyflavone have protective effects against insulin resistance and oxidative stress caused by high-fat diet in mice, and may prevent metabolic alterations associated with the development of metabolic syndrome and type<br/>2 diabetes.
