Abstract
This study was conducted to investigate the effects of dandelion leaf (Taraxacum officinale) extracts on hepatic antioxidative system in high cholesterol-fed rats. Four groups of rats were given high cholesterol diets containing 10 g cholesterol/kg and 2.5 g sodium cholate/kg for 6 weeks. The control group received a diet without dandelion leaf extract and the other three groups received dandelion leaf extracts, ie, water, ethyl acetate and ether extracts, respectively. There were no significant difference in cytochrome P-450 contents among four groups. Hepatic xanthine oxidase activity was significantly lower in water extract group than the other three groups. Superoxide dismutase activity was significantly lower in three dandelion leaf extract groups, but catalase activity was significantly higher in three dandelion leaf extract groups than control group. Glutathione peroxidase and glutathione S-transferase activities were significantly increased in water extract group than control group. Lipid peroxide content was decreased in water extract group than control group.
