摘要:

本文研究了八种药用植物(合欢花、鸡血藤、卷柏、茵陈、楮实子、续断、阔叶十大功劳、黄柏)的提取物对AChE的抑制活性。结果表明:这八种植物的不同溶剂萃取物(强碱层、正丁醇层、乙酸乙酯层)对AChE表现出不同程度的抑制作用。当样品浓度为1 mg/mL时,黄柏的强碱层、鸡血藤的正丁醇层和乙酸乙酯层对AChE具有较强的抑制活性(抑制率>50%),其IC50值分别为0.20±0.017、0.56±0.12和0.23±0.10 mg/mL。本研究为快速筛选天然植物中抑制AChE活性的有效部分提供了数据和方法支持。

Abstract:

The inhibitory effects of extracts from eight Chinese medicinal plants on acetylcholinesterase (AChE) were investigated.The results showed that the different solvent extracts of eight plants showed different inhibition on AChE.At the sample concentration 1 mg/mL,the strong alkaline extract of Cortex phellodendri and the n-butanol extract and the ethyl acetate extract of spatholobus sinensis showed the strong inhibitory effects against AChE (inhibition rate>50%).The corresponding IC50 values were obtained as 0.20±0.017,0.56±0.12 and 0.23±0.10 mg/mL,respectively.This study provided rapid screening of potential AChE inhibitors from Chinese medicinal plants.

Key words: Chinese medicinal plants, acetylcholinesterase inhibitors, screening, Ellman colorimetric method
