Phenolics were extracted from grape peels, and the compounds of grape peel phenolics (GPP) were identified by LC-MS/MS. From a perspective of dietary nutrition, this study aimed to evaluate the effect of GPP on lipid accumulation in sodium palmitate (PA)-treated HepG2 cells, and further to explore its mechanisms. HepG2 cells were induced by 0.4 mmol/L PA as an in vitro model of lipid accumulation. The results showed that GPP could significantly reduce the TG level and ROS production in PA-treated HepG2 cells. RT-qPCR and Western blotting analysis indicated that GPP supplementation can downregu...
