Abstract:AIM: To study the hepatoprotective effect of methanol extract of Gentiana veitchiorum (MGV) against CCl4-induced oxidative stress and liver injury in mice. METHOD: The acute hepatic model was developed byinjection of 20% CCl4 in mice. ICR mice were divided into six groups, including control, CCl4, CCl4(+) silymarin, and CCl4(+) MGV (100, 200, and 400 mg·kg(-1))groups. Hepatic enzymes including AST, ALT and ALP levels in serum, an dantioxidant enzymes, including SOD, CAT and GPX activity in liver tissue, were determined. Histopathological examination and Western blot analysis were performed. RESULTS: Oral administration of MGV at 200 and400 mg·kg(-1) for 15 days dose-dependently inhibited the serum elevations ofAST, ALT, and ALP, and recovered the reduction of SOD, CAT, and GPX in livertissue. Hematoxylin and eosin staining examination performed in liver tissues suggested that MGV treatment ameliorated histopathological changes inCCl4-induced mice. Western blotting analysis implied that MGV increased HO-1expression and recovered TNF-α alternation. CONCLUSION: G. veitchiorum can protect the liver against CCl4-induced damage in mice, and this hepatoprotective effect was dueat least in part to its ability through scavenging CCl4-associated free radical activities. The study provided in vivo evidence that G. veitchiorum can be used as a safe, cheap, and effective agent to reduce acute liver damage, supporting its folk medicine use.
