Figure 7: Blood glucose level at 2 hours in carbohydrate tolerance test. Hyperglycemic mice were given negative control (0.5% CMC-Na solvent), positive control (acarbose 10 mg/kg in starch test; metformin 200 mg/kg in glucose test) MF-L or H group (mangiferin 15 or 30 mg/kg), and NL-L or H (norathyriol 15 or 30 mg/kg). Mean with asterisk () represents significant () difference from negative control at given time by -tests.
