Purpose: Obesity is a risk factor for various adult diseases such as type 2 diabetes, cardiocerebrovascular disease, and cancer. With an increasing obesity population worldwide, the prevention of obesity with natural components has emerged as an alternative health care strategy. Ramulus mori (Sangzhi, RM) is widely used as a traditional herbal medicine in East Asia. It contains various phytochemicals, including stilbenes and 2-arylbenzofurans.
In this study, we compared the anti-obesity effects of RM extracts and its major stilbene components (mulberroside A [MSA] and oxyresveratrol [ORT]) in high fat diet (HFD)-fed obese mice.
Methods: Five week-old, male C57BL/6J mice were grouped into 7 experimental groups: normal diet (ND), HFD, HFD + 1% RM water extracts (MW), HFD + 0.1% MSA, HFD + 1% RM ethanol extracts (ME), HFD + 0.1% ORT, and HFD + 1% Garcinia cambogia extracts (GC) as a positive control. All mice were fed experimental diet for 13 weeks.
Results: Compared to the HFD group, total body weight and weekly body weight gain were significantly decreased in the ME, ORT, and GC groups. Glucose tolerance level was significantly decreased in all experimental groups, whereas plasma insulin level was decreased in MSA, ME, ORT and GC groups. Plasma glucose, triglyceride (TG), and total cholesterol levels were significantly decreased, whereas high-density lipoprotein cholesterol levels were increased in the MSA, ORT, and GC groups. Hepatic TG accumulation was also significantly decreased in the MSA, ME, ORT, and GC groups. Adipose tissue weight and size of adipocytes were significantly decreased in the MSA, ME and ORT groups, and were comparable to values obtained in the GC group. The levels of adiponectin and SREBP1c mRNA expressions were increased in the ORT and GC groups.
Conclusion: These results indicate that ME, ORT and MSA exert significant anti-obesity effect, and have the potential to be developed as a weight control ingredient of functional foods.
