牛蒡抗氧化、降血脂保健功能研究

Study of Health Protection on Antioxidation and Reducing Blood Lipid of Arctium lappa L.

利用大白鼠进行动物实验,研究牛蒡的抗氧化、降血脂保健作用。结果表明:牛蒡能显著降低高血脂大鼠的血清总胆固醇、甘油三酯和低密度脂蛋白水平,减小动脉硬化指标,对大白鼠高脂血症和动脉硬化具有较好的预防作用;牛蒡还能显著降低高血脂大鼠的肝系数、肝脏总胆固醇和甘油三酯水平,缓解肝脏的脂肪病变;牛蒡能提高大鼠红细胞内SOD活力、降低红细胞中MDA含量、提高血液中GSH-Px活力,从而清除机体内的超氧阴离子,减少机体受自由基的攻击。

The health protection with antioxidation and reducing blood lipid ofArctium lappa L. was studied. The rat experiments showed that serum lipid-lowering and antioxidative action of the Arctium lappa L. spent grains. Compared with the hyperlipidemic group, burdock-teas could significanfly lower the cholesterol levels of rats, including the serum TC, TG, LDL-C and arteriosclerosis index（AI）. It could also lower the liver weight, TC and TG. Arctium lappa L. also improved SOD activity, reduced MDA content in mice and enhanced GSH-Px activity in blood.
