Glucose-related parameters under administration of purple potato (PP) extract from Blue Congo variety: (A) fasting blood glucose; (B) glycated hemoglobin, % of total hemoglobin; (C) oral glucose tolerance test; (D) area under the curve after glucose load of rats. C—control group, C + PP—control rats receiving extract from Blue Congo (daily dose of 165 mg/kg body weight (b.w.) for 14 days), diabetes mellitus (DM)—diabetic group, DM + PP—diabetic rats treated with Blue Congo extract (daily dose of 165 mg/kg b.w. for 14 days). Results are shown as means ± SD. Significance was measured using one-way analysis of variance (ANOVA). Designations: ** p < 0.01, *** p < 0.001 compared to the control group; ## p < 0.01 compared to the DM group.
