Abstract: Salsolinol is a metabolite of alcohol and is cytotoxic, so that the salsolinol has been studied as a diagnostic biomarker for a liver disease and a liver cancer, but the salsolinol has not been reported as a therapeutic agent for the liver disease or the liver cancer. Since the salsolinol regulates tumor-related genes and inflammation-related genes specifically for men, it is experimentally found that the salsolinol has an effect of alleviating a liver cancer and an alcoholic hepatitis. Therefore, the salsolinol is contained together with a pharmaceutically acceptable salt as an effective ingredient and is provided as a pharmaceutical composition for treating the liver cancer or a health functional food for preventing and improving the alcoholic liver disease to have an effect of treating the liver disease and the liver cancer or preventing and improving the liver disease and the liver cancer.
