摘要

The effect of the administration of different doses of jaboticaba peel phenolic extract (JPPE) on serum biomarkers of hepatic, pancreatic, renal, and oxidative stress and the development of hepatic steatosis in rabbits was evaluated. In this trial, 36 rabbits were divided into six groups: control, hypercholesterolemic diet (HD), HD + 0.4 mg JPPE·kg·day−1, HD + 0.8 mg JPPE·kg·day−1, HD + 0.8 mg JPPE·kg·day−1 on alternate days and HD + 0.3 mg simvastatin·kg·day−1. JPPE consumption reduced levels of lipase and gamma-glutamyltransferase, prevented lipid peroxidation, and stimulated the activity of antioxidant enzymes in the animals’ livers. In addition, it was demonstrated that JPPE supplementation attenuates steatosis in hepatic tissue of rabbits. Therefore, the daily consumption of jaboticaba peel or its phenolic extract can prevent the oxidative and pancreatic damage generated by a hypercholesterolemic diet and the development of non-alcoholic fatty liver disease in rabbits.
