This study was designed to investigate whether Sasa borealis leaves extracts (SLE) may inhibit yeast α-glucosidase and α-amylase activities and postprandial hyperglycemia in STZ-induced diabetic mice. Freeze-dried SLE was extracted with 70% methanol and followed by a sequential fractionation with dicholoromethan, ethylacetate, butanol, and water. Both ethylacetate and butanol fractions showed high inhibitory activities against the α-glucosidase and α-amylase enzymes. The IC∧50 of ethylacetate and butanol fractions against α-glucosidase were 0.54 and 0.63 mg/mL, respectively, indicating a greater inhibition effect than acarbose (0.68 mg/mL) (p less than 0.05).
