CPE and CFSE regulate the blood glucose and insulin level. (A) Glucose tolerance test was performed by intraperitoneal injection of glucose (1 mL/kg body weight) into mice and blood glucoses were measured at 0, 15, 30, 60 and 90 min; (B) Area under the curve (AUC); and (C) Plasma insulin level. Values are means ± SE (n = 7). ^a,b,c,ab,bcmean values with different letters were significantly different (p < 0.05). HF: high-fat diet; HF + CPE: high-fat diet supplemented with citrange peel extract; HF + CFSE: high-fat diet supplemented with citrange fruit and seed extract.
