采用酸提碱沉、氯仿萃取法提取塔里木盆地8种有毒植物总生物碱,采用Ellman法,以他克林为阳性对照,探讨总生物碱抗A ChE活性。实验结果表明8种植物中小花棘豆、盐角草、叉枝鸦葱、骆驼刺、苦马豆总生物碱具有明显乙酰胆碱酯酶抑制活性,黄香草木犀,盐生草,白茎盐生草的抑制率相对较低。 The total alkaloids of eight species of poisonous plants in the Tarim Basin were extracted by acid-base precipitation and chloroform extraction. The Ellman’s method and tacrine were used as positive control to investigate the anti-A ChE activity of total alkaloids. The experimental results showed that the eight kinds of plants in the genus Houttuynia, salt grass, fork jackdaw, camel thorn, wild horse alkaloids alkaloids have obvious acetylcholinesterase inhibitory activity, yellow vanilla rhodiola, salt grass, white stem salt grass The inhibition rate is relatively low.
