title: Antidiabetic and hypolipidemic activities of Dillenia indica extract in diabetic rats.
abstract: OBJECTIVE
  The present study was carried out to investigate the antidiabetic and hypolipidemic activities of bioactive fraction (ethyl acetate fraction) of Dillenia indica methanolic extract in experimental diabetic Wistar rats.
  
  
  METHODS
  Type-1 diabetes was induced by single intraperitoneal injection of streptozotocin (60 mg/kg body weight), and type-2 diabetes was induced by single intraperitoneal injection of streptozotocin (60 mg/kg body weight), 15 min after the intraperitoneal injection of 120 mg/kg nicotinamide. The rats were treated by administering graded oral doses of isolated ethyl acetate fraction of methanolic extract of D. indica (DIEE), 200 and 400 mg/kg body weight, respectively, for 21 d. The blood glucose level was estimated at weekly intervals by glucometer. Serum cholesterol, triglycerides and high-density lipoprotein cholesterol (HDL-C) were also evaluated in normal and diabetic rats by an autoanalyzer.
  
  
  RESULTS
  In both experimental models, daily oral treatment with DIEE for 21 d resulted in a significant reduction in blood glucose (P<0.01), serum cholesterol (P<0.05) and triglycerides (P<0.05) levels whereas HDL-C level was found to be increased (P<0.05) as compared with the diabetic control group.
  
  
  CONCLUSIONS
  DIEE at 400 mg/kg body weight has prominent antidiabetic effect in experimental type-1 and type-2 diabetes models in rats. It may therefore be used as an alternative remedy for the treatment of diabetes mellitus.
