title: Antioxidant effects and hepatoprotective activity of 2,5-dihydroxy-4,3'-di(beta-d-glucopyranosyloxy)-trans-stilbene from Morus bombycis Koidzumi roots on CCl4-induced liver damage.
abstract: We investigated hepatoprotective activity and antioxidant effect of the 2,5-dihydroxy-4,3'-di(beta-D-glucopyranosyloxy)-trans-stilbene that purified from Morus bombycis Koidzumi roots against CCl4-induced liver damage in rats. The 2,5-dihydroxy-4,3'-di(beta-D-glucopyranosyloxy)-trans-stilbene displayed dose-dependent superoxide radical scavenging activity (IC50 = 430.2 microg/ml), as assayed by the electron spin resonance (ESR) spin-trapping technique. The increase in aspartate aminotransferase (AST) activities in serum associated with carbon tetrachloride (CCl4)-induced liver injury was inhibited by 2,5-dihydroxy-4,3'-di(beta-D-glucopyranosyloxy)-trans-stilbene and at a dose of 400 - 600 mg/kg samples had hepatoprotective activity comparable to the standard agent, silymarin. The biochemical assays were confirmed by histological observations showing that the 2,5-dihydroxy-4,3'-di(beta-d-glucopyranosyloxy)-trans-stilbene decreased cell ballooning in response to CCl4 treatment. These results demonstrate that the 2,5-dihydroxy-4,3'-di(beta-D-glucopyranosyloxy)-trans-stilbene is a potent antioxidant with a liver protective action against CCl4-induced hepatotoxicity.
