摘要
测定了核桃叶石油醚提取物对朱砂叶螨体内谷胱甘肽-S-转移酶、单胺氧化酶、Ca^(2+)Mg^(2+)- ATP酶、乙酰胆碱酯酶活性的影响。结果表明,核桃叶石油醚提取物处理朱砂叶螨后,螨体内谷胱甘肽-S -转移酶活性被激活;而乙酰胆碱酯酶、单胺氧化酶、Ca^(2+)Mg^(2+)-ATP酶的活力受到一定程度的抑制,这可能会引起神经传递的阻断,导致螨体的死亡。结果表明核桃叶作为新型植物源农药具有良好的开发前景。
Several kinds of important enzyme systems in Tetranychus cinnabarinus treated with petroleum ether extract of Juglans regia leaves were tested. The results indicated that the extracts of J. regia leaves had strongly acaricidal activities against T. cinnabarinus. The activities of glutathione-S-transferase in T. cinnabarinus were strongly induced, but the activities of acetylcholinease, monoamine oxidase and Ca^2＋Mg^2＋-ATPs were restrained. The result suggested that the petroleum ether extract of J. regia leaves may be the cause the transmit block of nerve in mites. The result from the experiment also indicated that the discovery had a good developing prospect for making full use of J. regia leaves as new resources of botanical acaricide.
