用中药黄精（Ｐｏｌｙｇｏｎａｔｕｍｓｐ．）中提取的多糖ＰＰ三种剂量连续灌胃老龄大鼠，于ｄ１５和ｄ３０进行迷宫测定，以检测黄精多糖对大鼠记忆获得和记忆再现的影响．结果显示：连续灌胃１５ｄ，黄精多糖能明显降低大鼠迷宫测试中的错误次数，显著提高大鼠学习和记忆能力；ｄ３０测试获同样结果，潜伏期测试表明能明显缩短潜伏期．另外ＰＰ对大鼠的体重变化无影响，也无副作用
The aged rats were given intragastrically by three doses of polysaccharide PP extracted from Polygonatum sp., and then measured on d15 and d30 to determine the effect of polygonatum polysaccharide on memory acquisition and memory reproducibility in rats. The results showed that: continuous gavage for 15 days, Polygonatum polysaccharide can significantly reduce the number of errors in the rat maze test, significantly improve the ability of learning and memory in rats; d30 test obtained the same results, latency test shows that it can significantly reduce the incubation period. In addition, PP has no effect on body weight changes in rats and has no side effects.
