Objective: Hyangsanondam-tang (⾹⼭溫膽湯, HSODT) is one of the Korean herbal formula for treatment of insomnia, neurosis and anxiety induced by liver Qi stagnation and unhealthy heart. We investigated the hepatoprotective effect of HSODT against arachidonic acid (AA) + iron-mediated cytotoxicity in HepG2 cells. Methods: AA + iron induced oxidative stress and mitochondrial dysfunction in HepG2 cells. The cytoprotective effects of HSODT were determined by MTT assay, western blot and fluorescence activated cell sorting analysis. Results: In HepG2 cells, pretreatment with HSODT significantly suppressed cytotoxicity and the expression of proteins related to apoptosis induced by AA + iron. In addition, pretreatment with HSODT significantly prevented the increase of H₂O₂ production, and decrease GSH depletion and mitochondrial membrane potential induced by AA + iron. Conclusions : These results indicated that HSODT could protect against oxidative stress-induced liver damage.
