Obesity is a chronic metabolic disorder that is characterized by excessive body fat and dysregulation of lipid metabolism. Hyperlipidemia in obesity is strongly associated with chronic diseases such as type 2 diabetes, cardiovascular disease, certain forms of cancer, and respiratory complications [1]. Currently two categories of medications are available to treat obesity: appetite suppressants and inhibitors of specific nutrient absorption. However, they often have undesirable side-effects. Therefore much attention has been focused on natural products, which may increase fat oxidation, decrease adipogenesis, and regulate lipid metabolism. AMP-activated protein kinase (AMPK) is regarded as important as it senses the cellular energy status and plays a critical role in the energy balance of the body through a concomitant inhibition of fatty acid synthesis and an activation of fatty acid oxidation [2]. Metabolic changes induced by AMPK involve both acute effects on the phosphorylation of key enzymes and chronic effects on the expression of genes involved in metabolic regulation [3]. Thus, AMPK has been recognized as a promising target for the management of obesity and hyperlipidemia
