| 摘 要： | 目的:研究枸杞粗多糖(Lycium Barbarum Polysaccharide,LBP)在小鼠体内的抗氧化作用。方法:用高(400mg/kg.d)、中(200mg/kg.d)、低(100mg/kg.d)剂量的枸杞粗多糖生理盐水溶液对D-半乳糖(100mg/kg.d)之衰老模型小鼠和正常小鼠灌胃。结果:枸杞粗多糖能较显著(P0.01)提高小鼠血清、肝脏及脑组织中SOD活性,降低MDA含量;极显著(P0.01)提高正常小鼠常压耐缺氧能力和游泳抗疲劳能力;此外小鼠的脾指数和胸腺指数均得到显著提高,表明枸杞粗多糖对提高小鼠的机体免疫水平具有重要的促进作用。结论:枸杞粗多糖对小鼠具有显著的抗氧化、抗衰老作用。

| Abstract: | Objective:To preliminary study rough mice anti - oxidant effection of Lycium Barbarum Polysaccharide. Method: Aging model and normal mice induced by D -galactose(100mg/kg·d)are igrrigated with three doses (400mg/kg·d, 200mg/kg.d, 100mg/kg·d)crude polysaccharide dissolved in normal saline. Result:LBP can increase SOD activities of serum,liver and brain organization, decrease the contents of their MDA(P <0.01) ;It also increases the survival time under hypoxic condition and swimming time of mice significantly (P<0.01) ;In addition, all LBP of different dose group can improve thymus index and spleen index of normal mice significantly. Conclusion: Lycium Barbarum Polysaccharide has an significant function of the anti - oxidant and anti - tumor on the mice. |
