Keyword:  海藻组分乙酰胆碱酯酶抑制剂活性筛选;
Abstract: 采用乙酰胆碱酯酶抑制剂活性筛选模型对采自青岛沿海的22种海藻样品提取物的石油醚组分和乙酸乙酯组分进行了活性筛选.结果表明,22种海藻的石油醚组分均具有不同程度的乙酰胆碱酯酶抑制活性,其中亮管藻、海头红、鸭毛藻和孔石莼表现出较强的活性,在浓度为50μg/ml时的抑制率均大于50.0%,分别为50.5%、55.5%、56.6%和65.8%;其他大部分海藻的抑制率在30.1%到48.9%之间.与石油醚组分不同的是,只有少数海藻的乙酸乙酯组分表现出乙酰胆碱酯酶抑制活性,其中鸭毛藻的活性最为显著,在浓度为25μg/ml时抑制率高达71.8%;孔石莼的乙酸乙酯组分也具有较强的抑制活性;其余海藻的乙酸乙酯组分对乙酰胆碱酯酶的抑制活性较弱,有些不仅没有活性,反而表现出不同程度的增强作用.
