Abstract: Triptolide, a purified diterpenoid from the herb Tripterygium wilfordii Hook.f., was widely used to treat many diseases. However, the hepatotoxicity of triptolide limited its clinical use. Research showed oxidative stress played an important role in triptolide-induced liver injury. To investigate the effect of vitamin C, which was one of the most effective antioxidants, on triptolide-induced hepatotoxicity and its potential mechanism in mice. In the present study, acute liver injury was induced by intraperitoneal injection of triptolide and vitamin C was orally administered. The results showed treatment with vitamin C prevented the triptolide-induced liver injury by reducing the levels of aspartate transaminase from 286.86 to 192.48 U/mL and alanine aminotransferase from 746.75 to 203.36 U/mL. Histopathological changes of liver corresponded to the same trend. Furthermore, vitamin C also protected the liver against triptolide-induced oxidative stress by inhibiting the generation of malondialdehyde (2.22 to 1.49 nmol/mgprot) and hydrogen peroxide (14.74 to 7.19 mmol/gprot) and restoring the level of total superoxide dismutase (24.32 to 42.55 U/mgprot) and glutathione (7.69 to 13.03 μg/mgprot). These results indicated that vitamin C could protect against triptolide-induced liver injury via reducing oxidative stress, and vitamin C may pose a significant health protection in the clinical use of triptolide.
