Abstract

This study had been done for the investigation of the effect of Vitis vinifera extract(V), Schisandra chinensis extract (S), Taraxacum officinale extract (T), Gardenia jasminoides extract (G), Angelica acutiloba extract (A) and Paeonia japonica extract (P), and their mixtures on the antioxidant and ethanol oxidation system which was induced by Lieber-DeCarli ethanol liquid diet. Male Sprague-Dawley rats were randomly divided into eight groups: ethanol diet (ED), normal diet (ND), ED+V (100 mg/kg/day), ED+S, ED+T, ED+G, ED+A and ED+P (300 mg/kg/day). We studied the effect on alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) after herbal extracts administration for 6 weeks in rats induced by Lieber-DeCarli ethanol liquid diet. The differences in ADH and ALDH activity of the rats treated with herbal extracts and ED group were not significant. Phase I enzyme activity was found to be significantly higher in the ED+V than the ED group. Phase II enzymes (glutathione-S-transferase, phenol sulfatransferase) activities were found to be higher in the herbal extracts than the ED group. Herbal extracts not only reduced ethanol-induced elevation of level malondialdehyde but also protected against ethanol-induced decrease of reduced glutathione, gluthione reducatse, glutathione peroxidase, catalase and superoxide dismutase activities. Therefore, they can be utilized as a health functional food or new drug candidate for fatty liver and hepatotoxicity which was induced by chronic alcohol consumption.
