The therapeutic effects of mulberry () leaves on lipid metabolism, including lipogenesis, lipolysis and hyperlipidemia are widely known, although their fermented products are yet to be applied. To investigate the therapeutic effects of a novel extract of mulberry leaves fermented with(EMfC) on lipid metabolism, the lipid profile of serum, lipid accumulation, lipolytic activity and lipogenesis regulation were measured in high fat diet (HFD)-induced obese C57BL/6 mice treated with EMfC for 12 weeks. Briefly, the concentrations of low-density lipoprotein, triglyceride, total cholesterol and glucose significantly decreased in the serum of the HFD+EMfC treated group when compared with the HFD+Vehicle treated group, while the levels of high-density lipoprotein increased in the HFD+EMfC group. The amount of abdominal fat and the size of adipocytes were significantly lower in the HFD+EMfC treated group when compared with the HFD+Vehicle treated group. The weight and number of lipid droplets of liver tissue exhibited a similar decrease. Furthermore, the mRNA levels of peroxisome proliferator-activated receptor-γ for adipogenesis as well as adipocyte protein 2 and Fas cell surface death receptor for lipogenesis reduced following EMfC treatment for 12 weeks. Phosphorylation of perilipin and hormone-sensitive lipase, and in the adipose triglyceride lipase expression showed a significant increase in the HFD+EMfC treated group. These results indicated that EMfC may prevent fat accumulation in the HFD-induced obese C57BL/6 mice through the inhibition of lipogenesis and by stimulating lipolysis. Thus, the results provide evidence for the potential use of EMfC as an anti-obesity complex in the treatment ofobesity.
