Abstract
Natural remedies from medicinal plants are considered to be effective and safe alternative treatments for diabetes mellitus. The current study deals with the effect of a single oral dose of the aqueous extract of Trichosanthes dioica. Roxb. (Cucurbitaceae) seeds in different diabetic animal models. Evaluation of the antihyperglycemic effect in normal, subdiabetic, and mild diabetic animal models is based on fasting blood glucose (FBG) and glucose tolerance test (GTT) studies. The graded doses of the extract, viz., 500, 750, 1000, and 1250 mg/kg body weight (b.w.), were administered orally. It was found that the blood glucose concentration decreased in a dose-dependent manner. The dose of 1000 mg/kg b.w. was found to be most effective with a maximum fall of 30.4% at 6 h during FBG studies in normal rats. However, the GTT studies showed the maximum reduction of 26.6% at 5 h in normal rats. Moreover, in case of subdiabetic and mild diabetic rats, the observed reduction in blood glucose levels was 32.8% and 35.9%, respectively, at 3 h during GTT. The data clearly reveal the significant antihyperglycemic profile of Trichosanthes dioica. seeds.
