MATERIALS AND METHODS
UPLC-PDA-ESI-MS method was established for the analysis of the components in EAFVC, which was further separated using multiple chromatographic techniques. The MS, 1H and 13C NMR were applied to elucidate their structures. UPLC-PDA method was applied for the simultaneous quantification of major compounds of EAFVC. Furthermore, the protective effect of the EAFVC was determined using APAP-induced acute hepatotoxicity in mice and BRL-3A cells model, respectively. In addition, the hepatoprotective activity of two main compounds in EAFVC on relieving APAP-induced liver injury was further evaluated. Finally, we have some concerns about the protective mechanism of EAFVC via enzyme-linked immunosorbent assay (ELISA), reactive oxygen species (ROS) detection, quantitative real-time PCR (qPCR), western blot analysis and molecular docking.
