However, the antioxidant status and systematic changes in metabolic biochemistry associated with saccharicterpenin supplementation in animals are still unknown. This study examined the effects of saccharicterpenin on the antioxidant status and urinary metabolic profile of rats. Sixteen rats were randomly distributed to 2 groups. One group was treated with 400 mg/kg body weight of saccharicterpenin, and the other group was treated with equal amount of saline. Results revealed that saccharicterpenin significantly increased the capacities of antihydroxyl radical(13.18%) and anti-superoxide anion(14.36%), the total antioxidant capacity(48.27%),and the activities of total superoxide dismutase(3.68%), catalase(21.52%), glutathione peroxidase(5.83%)and glutathione S-transferase(29.59%)(P < 0.05). By contrast, the contents of malondialdehyde and glutathione were not significantly affected by saccharicterpenin(P > 0.05). Saccharicterpenin supplementation significantly increased the urinary levels of bile acids, ethanol. α-ketoglutarate, and a-hydroxy butyrate but decreased the level of N-acetylglutamate(P < 0.05). In summary, saccharicterpenin can enhance the antioxidant capacity and modulate the metabolism in rats.展开更多
