Mung bean coat ameliorates hyperglycemia and the antioxidant status in type 2 diabetic db/db mice

The hypoglycemic and antioxidant effect of mung bean coat (MBC) in an animal model of type 2 diabetes was investigated. A 95% ethanol extract of MBC inhibited yeast α-glucosidase activity by 48.6% in vitro , which was 1.4× stronger than inhibition by acarbose at a concentration of 0.5 mg/mL. Five week old db/db mice were fed an AIN-93G diet or a diet containing the MBC extract at 1% for 7 weeks. Blood glycated hemoglobin and serum glucose levels, as well as the homeostasis model assessment for insulin resistance in MBC group mice, were significantly ( p
