Background: α-glucosidase inhibitors controls postprandial hyperglycemia (PPHG) by lowering sharp rise in blood glucose levels after ingestion of carbohydrate rich meal in type 2 diabetic (T2D) individuals. Acalypha indica commonly known as Indian copper leaf is used in traditional medicinal system to treat various diseases. In our previous in-vitro investigation, methanolic extract of A. indica stems (AIS) proved to be an effective a-glucosidase inhibitor, antioxidant, and well tolerated in acute and subchronic toxicity studies in albino wistar rats Objective: In this perspective, this study was designed to evaluate postprandial antihyperglycemic potential of AIS in maltose, sucrose, and glucose loaded streptozotocin (STZ)-induced normal and diabetic rats. As, the acute hyperglycemia at postprandial period has more triggering effect on oxidative stress, study was also aimed to evaluate the antioxidant potential of AIS on STZ-induced Albino-Wistar rats. Materials and Methods: Rats were treated with AIS (300-600 mg/kg b.w.) to investigate effect of AIS in controling PPHG after carbohydrate loading. Hepatoprotective activity of AIS is evaluated in diabetic rats by treating them at the dosages 300-600 mg/kg b.w. Results: Studies revealed 69.10 and 80.35% blood glucose-lowering effect of AIS in maltose and sucrose loaded diabetic rats in comparison with the diabetic control group. AIS recovered the liver damage caused by streptozotocin Conclusion: The present study confirmed high potential of AIS in controling PPHG by inhibiting a-glucosidase enzyme in maltose and sucrose loaded diabetic rats. AIS also exhibited hepatoprotective activity in STZ-induced diabetic rats. Thus, AIS could be used as a nutraceutical supplement to treat T2D effectively.
