Antihyperglycaemic effect of Casearia esculenta root extracts in streptozotocin-induced diabetic rats.Pharmazie. 2002 Nov; 57(11):758-60.P
The present study was carried out to evaluate the antihyperglycaemic effect of Casearia esculenta root extract and to study the activities of liver hexokinase and gluconeogenic enzymes such as glucose-6-phosphatase and fructose-1,6-bisphosphatase in liver and kidney of normal and streptozotocin-induced diabetic rats. Oral administration of aqueous extract of root (300 mg/kg body weight) for 45 days resulted in a significant reduction in blood glucose from 250.79 +/- 12.65 to 135.70 +/- 8.90 and in a decrease in the activities of glucose-6-phosphatase and fructose-1,6-bishosphatase and an increase in the activity of liver hexokinase. However, in the case of 200 mg/kg body weight of extract, less activity was observed. The study clearly shows that the root extract of C. esculenta possesses potent antihyperglycaemic activity but weaker than that of glibenclamide.
