摘要

牛心朴子对线虫的杀线活性的研究证实,牛心朴子甲醇提取物对松材线虫的杀线活性随时间和提取物浓度增加明显增加;紫外线和加热处理会使其提取物失活,提取物的新鲜度会影响其活性。分析认为牛心朴子的毒性机理是干扰线虫葡萄糖和蛋白质代谢,抑制SOD活性,诱导POD和CAT活性,进而产生自由基摧毁保护酶系统,同时抑制AChE活性,破坏神经系统,抑制GST活性,并干扰解毒酶系统的代谢。四合木的毒性机理是干扰线虫葡萄糖和蛋白质代谢,抑制SOD活性,诱导POD和CAT活性,进而产生自由基或改变酶分子,这样就会导致损毁保护酶系统,对AChE和AKP的作用类似牛心朴子的情况。鄂尔多斯半日花的毒性机理是干扰线虫葡萄糖和蛋白质代谢,抑制SOD活性,诱导POD和CAT活性,进而产生自由基摧毁保护酶系统,同时抑制AChE活性,破坏神经系统。
