【Abstract】 Objective To study the hypoglycemic effects of extracts of Alpinia officinarum Hance (galangal)
on type 2 diabetic model mice. Methods Streptozocin (STZ) and high fat and high-sugar diet were used to induce type
2 diabetes in mice. The glucose levels, body weight, and food intaking in feeding process were observed. After the blood
sugar levels in mice reaching tested requirements, galangal extract, metformin, and normal saline were orally given to
mice. After 30 days, the fasting blood glucose, pathological section, and other factors were investigated. Results Ad-
ministrating galangal extract to mice led to a significant decrease in their 2 h blood glucose concentration after a glucose
tolerance test (P<0.05), which also had a regulative effect on body weight (P<0.05). In the group of 50 mg/kg galangal
extract, significant improvement was observed in the fasting blood glucose (P<0.05), but no significant improvement
was found in the recovery of liver damage and fatty degeneration. Conclusion The galangal extract has hypoglycemic
effects on the blood sugar in type 2 diabetic model mice.
