Abstract

This study aimed to evaluate the protective effect of Orostachys malacophyllus (OM) and fermented O. malacophyllus (FOM) in Sprague-Dawley rats who had been intoxicated with 1% (w/w) orotic acid (OA) for 10 days. The activities of several hepatic enzymes, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and cholinesterase, were increased when OA was given, but these parameters were significantly decreased by FOM treatment. In addition, OA treatment resulted in an increased lipid peroxidative index (thiobarbituric acid-reactive substances, TBARS). A worsened antioxidant status (reduced glutathione) in the liver and serum was also observed. FOM treatment improved the antioxidant status of OA-induced fatty-liver rats, which was evaluated by decreased levels of the lipid peroxidative index and improved antioxidant status in the liver and serum. The contents of liver non-heme iron were increased with OA treatment and significantly decreased with FOM treatment, which suggested that the lipid peroxidation contents were inversely correlated with liver non-heme iron content. Based on these results, FOM is considered a material with significant potential for development into a functional health food that can improve fatty-liver conditions.
