Inhibition effects of tea flower extract on glucose absorption in experimental glucose tolerance mice / 国际药学研究杂志

Objective To study the inhibitory effects of tea flower extract (TFE) on α-glucosidase and glucose intestinal absorption. Methods Three different postprandial hyperglycemia models (2 g/kg glucose, 4 g/kg sucrose, and 6 g/kg starch) were used, with 8 mice in each group. Oral administration of 150 or 300 mg/kg of TFE, 6.25 mg/kg of acarbose, or water was performed on mice 1 day and 30 mins before the oral administration of 2 g/kg glucose, 4 g/kg sucrose, and 6 g/kg starch at 10 ml/kg of body weight. Blood glucose levels were analyzed chronologically to evaluate the effect of TFE. In vitro studies were also performed to study the inhibitory effects of TFE on α-glucosidase and small intestinal mucosa glycosidase.
