1、LISHIZHENMEDICINEANDMATERIAMEDICARESEARCH2013VOL.24NO.9时珍国医国药2013年第24卷第9期覆盆子不同萃取部位对东茛菪碱所致学习记忆障碍大鼠的影响黄丽萍,熊玉洁,赵梦岚,龚嘉华,谢一辉(江西中医药大学,江西南昌330004)摘要:目的考察覆盆子不同萃取部位对氢溴酸东莨菪碱所致学习记忆障碍大鼠的影响,摸索覆盆子改善学习记忆能力的有效部位。方法大鼠分别灌胃给予覆盆子不同萃取部位12g生药/kg,连续3周,空白组和模型组灌胃等量生理盐水。测试前30min,除空白组外,所有大
2、鼠用氢溴酸东莨菪碱Zing/kg腹腔注射,造成学习记忆障碍动物模型,检测大鼠在Mor.s水迷宫中的逃避潜伏期、空间探索能力。结果覆盆子氯仿部位、正丁醇部位、乙酸乙酯部位、水部位均可不同程度缩短大鼠的逃避潜伏期,增强大鼠的空间探索能力,均有一定的改善东莨菪碱所致学习记忆障碍大鼠学习记忆的能力。结论覆盆子氯仿部位、正丁醇部位、乙酸乙酯部位、水部位具有改善东莨菪碱所致痴呆大鼠学习记忆的功能。关键词:覆盆子萃取部位;东莨菪碱;Morris水迷宫;学习记忆D0I标识:doi:10.3969/j.issn.1008-0805.201
