Popis: We investigated the radical scavenging activity and protective effects of the methanol extract (ME) and ferulic acid (FA) from baemuchae (xBrassicoraphanus) against oxidative stress in vitro and on a cellular system using LLC-PK1 renal epithelial cells. In vitro, ME and FA showed dose-dependent radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals. LLC-PK1 cells displayed decreased viability in response to nitric oxide-induced oxidative stress. However, ME and FA significantly increased LLC-PK1 cell viability in a dose-dependent manner. Based on HPLC/UV analysis, the FA content was higher in the shoot of baemuchae than in the root. The results of the present study suggest that baemuchae may be a promising source of antioxidants against oxidative stress induced by free radicals.
