Antidiabetic activity of aqueous extract of Eucalyptus citriodora Hook. in alloxan induced diabetic rats

Abstract

The present study was undertaken to study the antidiabetic activity of the aqueous extract of Eucalyptus citriodora Hook. leaf in alloxan-induced diabetic rats. The activity of the extract was studied on glucose loaded and alloxan-induced diabetic rats. In both the tests, the extract has shown significant and considerable antidiabetic effect in a dose dependent manner. On oral administration of the extract at a dose of 500 mg/kg of body weight, the reduction of blood glucose level was 22.9% after 4th hr and on continuous administration the reduction in blood glucose level after 21 days was 49.9 and 56.8% with dose of 250 and 500 mg/kg of body weight respectively. Aqueous extract of leaves of E. citriodora exhibited significant antidiabetic activity which was comparable with the standard drug Glibenclamide.
