The purpose of this study was to evaluate the antioxidative potential of Korean wild leaf vegetables in vivo as well as in vitro. The antloxidative activities of Pleurospemum kamtschaticum, Aderophora remotiflor and Aster gfheni were evaluated as a reference for Spinacia oleracea. Fifty rats were find either a control diet or one of several vegetable diets for 4 weeks. The level of thiobarbituric acid reactive substance (TBARS) and the activity of catalase and superoxide dismutase (SOD) in the liver were compared. The levels of total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG) in plasma were also compared. Also, the contents of β-carotene, vitamin C, vitamin E and total phenolic compound, including flavonoid and thiobarbituric acid (TBA) value using linoleic acid model system, were measured in Korean wind leaf vegetables. The TBARS values of Aderophora remotiflor and Aster giheni tended to be lower than that of Spinacia olerncea. The SOD activity of Artrr glheffi was significantly higher than that of Spinacia oleracea and reached 265% that of the control animals, whereas there was no difference between the control animals and the vegetable diet animals in terms of catalase activity. Compared to the control animals, TG and TC levels were significantly solver and showed a lower artheriosclerotic index. TBA values of Pleurospemum Kamschaticum and Aderophora remptiflor were only 18% of control value. TBA value of Spinacia olerucra was 41% of control value. These results suggest that Aderophora remotinor and Aster glheni could have antioxidative potency in vivo as well as in vitro and potential value far functional flood to improve the plasma lipid profile. flavonoid and phenolic compounds could be the major contributing factor in the antioxidative potential of Aderophora remotiflor and Aster glheni.
