We examined the hepatoprotective activity of Inonotus obliquus water extract (IO-W) against tertbutyl hydroperoxide (t-BHP)–induced oxidative liver injury in the primary cultured rat hepatocyte. The 50% radical scavenging concentrations (SC50s) of IO-W for radical-scavenging activity against 2,2′-azino-bis-(3-ethylbenzothiazoline- 6-sulfonic acid) (ABTS) and 1,1-diphenyl-2-picryl-hydrazyl (DPPH) were 5.19 mg/mL and 0.39 mg/mL, respectively. IO-W pretreatment to the primary cultured hepatocytes significantly (p100 μg/ mL). In conclusion, this study demonstrates that IO-W exhibited hepatoprotective activity against t-BHP–induced oxidative liver injury in the primary cultured hepatocyte probably via its abilities of quenching free radicals, inhibiting the leakage of ALT, AST, and LDH, and decreasing MDA formation.
