Antihyperglycemic activity of Piper betle leaf on streptozotocin-induced diabetic rats.

| Abstract |
Piper betle, an indigenous medicinal plant, has a folk (Siddha and Ayurvedha) reputation in the rural southern India. The present study was carried out to evaluate the effect of P. betle on glucose metabolism since it is consumed as betel-quid after meals. Plasma levels of glucose and glycosylated hemoglobin and activities of liver hexokinase and gluconeogenic enzymes such as glucose-6-phosphatase and fructose-1,6-bisphosphatase in control and streptozotocin (STZ) diabetic rats were assayed. Oral administration of leaf suspension of P. betle (75 and 150 mg/kg of body weight) for 30 days resulted in significant reduction in blood glucose (from 205.00 +/- 10.80 mg/dL to 151.30 +/- 6.53 mg/dL) and glycosylated hemoglobin and decreased activities of liver glucose-6-phosphatase and fructose-1,6-bisphosphatase, while liver hexokinase increased (P < .05), in STZ diabetic rats when compared with untreated diabetic rats. P. betle at a dose of 75 mg/kg of body weight exhibited better sugar reduction than 150 mg/kg of body weight. In addition, protection against body weight loss of diabetic animals was also observed. The effects produced by P. betle were compared with the standard drug glibenclamide. Thus, the present study clearly shows that P. betle intake influences glucose metabolism beneficially.
