The present study, we investigate the preventive role of naringin, a dietary flavonoid, against ultraviolet‐B (UVB) radiation (280‐320 nm) induced oxidative damage and inflammatory responses in mouse embryonic fibroblast cell lines (NIH‐3T3). In this study, 20 mJ/cm 2 of UVB radiation induces cell cytotoxicity, reactive oxygen species (ROS) generation, DNA damage, and antioxidants depletion in NIH‐3T3 cells. Treatment with naringin (60 µM) prior UVB exposure prevented the cell cytotoxicity, ROS generation, DNA damage, and antioxidants depletion in NIH‐3T3 cells. Furthermore, naringin prevents UVB‐induced mitogen‐activated protein kinase families and nuclear factor‐κB (NF‐κB)‐mediated activation of inflammatory factors, that is TNF‐α, IL‐6, IL‐10, and COX‐2 in NIH‐3T3 cells. Peroxisome proliferator‐activated receptor γ (PPARγ) is an anti‐inflammatory agent and it suppressed the UVB‐mediated oxidative and inflammatory responses. In this study, naringin activates PPARγ and prevents inflammatory biomarkers in NIH‐3T3 cells. Thus, naringin prevents UVB‐mediated inflammation and oxidative damage in NIH‐3T3 cells probably over controlling NF‐κB expression and activation of PPARγ.
