This study investigated the effect of pummelo extract (Citrus maxima) on biochemical, inflammatory, antioxidant and histological changes in NAFLD rats. Forty male Wistar rats divided into four groups were used: (1) control group; (2) fructose associated with high-fat diet - DHF; (3) normal diet + pummelo extract (50 mg/kg); and (4) FHD + pummelo extract. This was administered at dose of 50 mg/kg of the animal's weight, by gavage, for 45 days. Significant improvement in lipid profile, liver and kidney function, inflammation, oxidative stress markers was identified in group 4 compared to group 2. Regarding TNF-α and IL-1β, group 2 showed higher values (respectively 142, 5 ± 0.7 and 560.5 ± 2.7 pg/mg protein) compared to group 4 (respectively 91.4 ± 0.9 and 402.1.4 ± 0.9 pg/mg protein), p < 0.05. Significant increases were found in SOD and CAT activities, respectively 0.10 ± 0.06 and 8.62 ± 1.67 U/mg protein for group 2 and respectively 0.28 ± 0.08 and 21.52 ± 2.28 U/mg of protein for group 4. Decreases in triglycerides, hepatic cholesterol and fat droplets in hepatic tissue were observed in group 4 compared to group 2. Results highlight that pummelo extract may be useful for prevent the development of NAFLD.
