麦糟戊聚糖降脂功能研究

Lipid-lowering and Antioxidative Action of Soluble Pentosan Isolated from Beer`s Spent Grains in Mice

利用小白鼠进行动物实验证明:麦糟戊聚糖能显著降低高血脂小鼠的血清总胆固醇、甘油三脂和低密度脂蛋白水平,减小动脉硬化指标,对小鼠高脂血症和动脉硬化具有较好的预防作用;麦糟戊聚糖能显著降低高血脂小鼠的肝系数、肝脏总胆固醇和甘油三酯水平,缓解肝脏的脂肪病变;麦糟戊聚糖能提高小鼠红细胞内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 mice experiments showed serum lipid-lowering and antioxidative action of the Pentosan isolated from beer＇s spent grains. Compared with the hyperlipidemic group, Pentosan isolated from beer, s spent grains could significantly lower the cholesterol levels of mice, including the serum TC, TG, LDL-C and arteriosclerosis index（AI）. It could also lower the liver weight, TC and TG. Pentosan isolated from beer＇s spent grains also improved SOD activity, reduced MDA content in mice and enhanced GSH-Px activity in blood.
