Abstract
In continuation of our previous work on Trichosanthes dioica Roxb. (Cucurbitaceae), the aim of this study was to screen the glycemic attributes of an aqueous extract of Trichosanthes dioica leaves in normal as well as various diabetic models. The variable doses of 250, 500, and 750 mg kg− 1 body weight (bw) of the extract were administered orally to normal and streptozotocin (STZ)-induced sub- and mild-diabetic rats in order to define its glycemic potential. The dose of 500 mg kg− 1 bw was identified as the most effective dose which brings down the blood glucose level (BGL) by 32.9% (P < 0.001) at 6 h during fasting blood glucose (FBG) studies in normal rats. However, glucose tolerance test (GTT) showed the maximum reduction of 30.9% (P < 0.001) in BGL at 5 h in normal rats with the same dose, whereas the reduction observed was by 40.3% and 88.6% (P < 0.001) in sub- and mild-diabetic rats, respectively, at 3 h of glucose administration only. This evidence clearly indicates that the aqueous extract of Trichosanthes dioica leaves has good hypoglycemic potential along with a high anti-diabetic profile.
