摘要
胜红蓟挥发油对真菌、昆虫和植物均具有生物活性 ,对植物致病真菌和害虫的抑制活性尤其显著。挥发油及其主要成分胜红蓟素不仅具有杀虫活性 ,而且引起昆虫拒食和延迟蜕皮。用 GC/MS详细分析了胜红蓟挥发油的化学成分 ,共鉴定了 2 7个化合物 ,胜红蓟素及其衍生物 ,单萜和倍半萜类化合物是其主要成分。
The volatile oil of Ageratum conyzoides had siqnificant biological actirities on fungi,insects and plants,particalarly on plant diseases and insect pests.The volatile oil and its major component precocene Ⅱ not only had insecticidal efficacy,but also anti\|feeding effect and delayed molting of insects.The chemical constituents of the volatile oil from A.conyzoides were analyzed in detail by means of GC/MS.Twenty\|seven compounds were identified,and ageratochromene with its derivatives as well as monoterpenes and sesquiterpenes are major components.
