摘　　要：玛咖(Lepidium meyenii Walp.)是原产南美洲安第斯山脉的一种十字花科植物,是独行菜属中唯一生有肥厚的下胚轴的物种,富含高单位营养素,对人体有滋补强身的功用。为了揭示植物玛咖(Lepidium meyenii Walp)多糖的运动医学价值,本研究考察了不同乙醇体积分数(60%,70%,80%,90%)提取的玛咖多糖(Lepidium meyenii polysaccharide,LMP)的抗疲劳作用及机制。研究结果表明,玛咖多糖可有效提高力竭游泳大鼠的抗疲劳能力,其机制可能与激活AMPK/PGC-1α信号通路有关;使用体积分数为60%的乙醇溶液提取的多糖具有更好的抗疲劳作用。Maca(Lepidium meyenii Walp.),a cruciferous plant originating from the Andes Mountains of South America,is the only species in the genus Lepidium with plump hypocotyls.It is rich in high unit nutrients and has the function of nourishing and strengthening the human body.In order to reveal the sports medicine value of Maca polysaccharide,this study investigated the anti-fatigue effect and mechanism of Lepidium meyenii polysaccharide(LMP)extracted with different ethanol volume fractions(60%,70%,80%,90%).The results showed that Maca polysaccharide can effectively improve the anti-fatigue ability of exhausted swimming rats,and its mechanism may be related to the activation of AMPK/PGC-1αsignal pathway;The polysaccharide extracted with 60%ethanol solution has better anti-fatigue effect.
