Effects of Diet with Added Butterbur (Petasites japonicus Maxim) on the Plasma Lipid Profiles and Antioxidant Index of Mice

We evaluated the effects of butterbur (Petasites japonicus Maxim) addition to the diet on lipid profiles and antioxidant biomarkers such as total glutathionine, TBARS value, carbonyl value, GPx, GR, SOD and paraoxonase activity in the plasma or liver of mice. The distribution of body fat deposition, total cholesterol (TC) contents, and atherogenic index in the plasma were significantly decreased in the butterbur group. The levels of GSH and the activity of GR and SOD were significantly higher in the liver of the butterbur group than in that of the control group. Lipid oxidation of the liver and kidney and protein oxidation of the liver and heart were decreased in the butterbur group. Additionally, the DNA damage, as determined using the comet assay (single cell gel assay) with alkaline electrophoresis and as quantified by measuring the tail length (TL), was decreased in the butterbur group. The results of the present study showed that a diet with added butterbur exerts degenerative disease-protective effects on oxidative DNA damage and lipid peroxidation.
