This study was conducted to examine antioxidative activity and lipid composition from different parts and supplement flesh and skin of Codonopsis lanceolata in vivo. Forty six?week?old white Sprague Dawley rats were divided into 5 groups and fed with experimental diet for six weeks to measure antioxidant enzymes activities and lipid composition in blood and liver microsome. The activity of glutathione peroxidase in blood was high in all groups supplemented with Condonopsis lanceolata and the difference was observed in accordance with the supplemented part rather than the supplemented level. However, glutathione reductase activity and the content of malondialdehyde (MDA) in blood showed difference depending on the level of supplementation rather than the supplemented part. The content of liver MDA in all groups supplemented with Condonopsis lanceolata was lower than that in the control group. As the level of skin supplementation increased, an increase in glutathione peroxidase activity was also observed. Only in the group that 5% of Condonopsis lanceolata skin was supplemented, the glutathione reductase activity was higher than in the control group. Total cholesterol and LDL?cholesterol of blood in the group supplemented with Condonopsis lanceolata flesh or skin were significantly lower than those in control group. HDL?cholesterol in blood was high when the flesh of Condonopsis lanceolata was supplemented. Total cholesterol and triglyceride in liver of the group supplemented with Condonopsis lanceolata flesh or skin were significantly lower than those in control group. In summary, this animal test showed that the supplementation of Condonopsis lanceolata, fleshor skin, generally improved the antioxidative effect of diet and lipid composition.
