Effect of Coffee of water and ethyl alcohol extracts on sucrose loading test. After fasting for 24 h, 4-week-old, male SD rats were orally administered with sucrose (2.0 g/kg-body weight (bw)) with or without samples (GWE, EWE, SWE, GEE, EEE, SEE of 0.5 g/kg-bw, and Acarbose 5.0 mg/kg-bw). Each point represents mean ± S.D. (n = 5). *p < 0.05 and ***p < 0.001 compared to different samples at the same concentration by unpaired Student’s t-test
