摘 要:目的对采自浙江天目山的40种蕨类植物丙酮提取物进行乙酰胆碱酯酶活性抑制作用的研究。方法采用乙酰胆碱酯酶抑制活性筛选模型。结果在供试质量浓度在1mg/mL时,40种植物的丙酮提取物均具有明显的的乙酰胆碱酯酶抑制活性,其中假长尾复叶耳蕨、假蹄盖蕨和延羽卵果蕨等11种蕨类植物表现出较强的抑制活性,抑制率均大于90%,其余大部分植物的抑制率均大于60%。而在供试质量浓度在0.025mg/mL时,只有少数植物表现出较高的乙酰胆碱酯酶抑制活性,其中虎尾铁角蕨的抑制率为(65.36±1.65%),蜈松草的抑制率为(53.30±3.32%),其余大部分植物的抑制活性均小于50%,甚至有些植物提取物不仅对乙酰胆碱酯酶没有抑制活性,反而表现出一定的增强作用。结论假长尾复叶耳蕨等蕨类植物丙酮提取物的乙酰胆碱酯酶抑制作用值得进一步研究。Objective: To study the inhibitory effects of forty ferns (collected from Tianmu mountain,Zhejiang province) acetone extracts on acetylcholinesterase(AChE) activity.Methods : Riddling model of acetylcholinesterase activity inhibition was used.Results:The results showed that under the concentration of 1mg/mL,most of the acetone extracts of 40 ferns had high inhibition rates.More than 11 kinds of plants such as Arachniodes pseudo-simplicior,Athyriopsis japonica and Phegopteris decursive-pinnata etc.had high inhibition rates more than 90% to AChE.However,under the concentration of 0.025 mg/mL,most of the acetone extracts of 40 plants had low inhibition rates less than 50%,except Asplenium incisum and Pteris vittata had (65.36±1.65%) and(53.30±3.32%) inhibition rates respectively.Further more,some plant extracts even enhanced this enzyme activity.Conclusion: These plants such as Arachniodes pseudo-simplicior,Athyriopsis japonica and Phegopteris decursive-pinnata etc.as a source of AChE inhibitor are worthy of further study.
