In recent years, obesity and diabetes have become the epidemic mainly due to fast food and lifestyle changes. Several herbs have been claimed to control diabetes and obesity. However, there are a few which control both. Our aim was to evaluate the anti-diabetic and anti-obesity activity of methanolic extract of Memecylon umbellatum (MU) in alleviation of insulin resistance (IR). Diet induced obese (DIO) mice model was developed by feeding the mice on high fat diet (HFD) for 10 weeks resulting in hyperglycemia, obesity and IR. 250mg/kg body weight of extract was administered orally daily for 8 weeks. Fasting glucose and body weight were monitored throughout the experiment. At the end of the study, serum parameters, histological examinations and gene expression pattern were analyzed. There was a significant reduction in fasting glucose levels, body weight and triglycerides. Improvement in the glucose tolerance and amelioration of insulin resistance was observed as revealed by reduction in serum IL6, serum oxidised LDL, histological sections of liver and subcutaneous adipose. Gene expression studies demonstrated the anti-inflammatory activity of the extract by down regulating IL6, PAI1 and ApoB gene expression as compared to the untreated HFD control. Our results demonstrate for the first time that oral administration of methanolic extract of MU in DIO mice leads to reduction in hyperglycemia, body weight, triglycerides and ameliorates insulin resistance. Further, mechanism of action of the extract needs to be investigated by purifying the extract and analyzing the active ingredient playing the major role.
