However, its antidiabetic activity is unreported. In this study,\n                    <jats:italic>G. alata<\/jats:italic>\n                    methanolic extract was tested for its antidiabetic, antioxidant, and \u03b2-cell modulatory effects in a streptozotocin-induced diabetic rat model. In this model of diabetic rats, the oral glucose tolerance test with\n                    <jats:italic>G. alata<\/jats:italic>\n                    extract at 125, 250, and 500\u200amg\/kg doses revealed the efficacy of the 250\u200amg\/kg dose in improving glucose tolerance comparable to the standard drug glibenclamide. Diabetic rats were treated with a 250\u200amg\/kg dose of\n                    <jats:italic>G. alata<\/jats:italic>\n                    extract orally for 2\u200ah (acute) or 14 days (chronic). In the case of acute treatment, the extract lowered blood glucose levels significantly at 120\u200amin both in nondiabetic and diabetic rats. Chronic treatment of diabetic rats with 250\u200amg\/kg of\n                    <jats:italic>G. alata<\/jats:italic>\n                    extract resulted in a significant decrease in blood glucose level closer to that of nondiabetic rats. Interestingly, increased serum insulin, improved \u03b2-cell function, and antioxidant status were observed in\n                    <jats:italic>G. alata<\/jats:italic>\n                    -treated diabetic rats.\n                    <jats:italic>G. alata<\/jats:italic>\n                    also showed strong antioxidant and \u03b1-glucosidase inhibitory activities in\n                    <jats:italic>in vitro<\/jats:italic>\n                    assays.
