Antidiabetic potential of Andrographis echioides Nees. leaf extract on high fat diet-fed C57BL/6J diabetic mice

The present study validates the antidiabetic potential of Andrographis echioides leaf extract (AeLE) on high fat diet-fed diabetic C57BL/6J mice. The male C57BL/6J mouse (age 6-8 weeks) were divided into 2 groups (lean control group and diabetic group). The lean control group (6 animals) was fed with standard diet pellets. The diabetic group animals (24 animals) were made diabetic by feeding a high-fat diet for 12 weeks. This group was then further divided into 4 groups of 6 animals each and treated orally (for 28 days) with vehicle (0.5%carboxymethyl cellulose), metformin 100mg/kg body weight and 2 different concentrations of test drug viz., 100mg/kg and 200mg/kg body weight. The results show a significant reduction in blood glucose and other biochemical parameters. After 28 days, the metformin and AeLE (200 mg/kg b.w) treated animals had an average serum glucose value of 129.69±1.97 mg/dl and 109.6±3.92 mg/dl, respectively. Also, the liver markers were positively affected by AeLE. In conclusion, A. echioides leaf extract was found to reduce hyperglycemia and significantly improve the biochemical profile of the mice.
