紫茎泽兰不同部位的化学成分及其生物活性*

 到目前为止,已经从紫茎泽兰这种重要的外来入侵植物中分离出100余种化学成分,这些化学成分的主要种类有单萜类、倍半萜类、三萜类、甾体类、黄酮类、苯丙素类及各类衍生物。紫茎泽兰化学成分的生物活性主要表现为杀虫、抑菌和对其它植物的化感作用等。简要介绍了紫茎泽兰不同部位的化学成分及其生物活性研究的进展,为深入探讨紫茎泽兰对生物多样性的影响机理和新型仿生农药先导化合物的开发,提供参考。

The Chemical Compositions and Their Bioactivities in the Different Parts of Eupatorium adenophorum Spreng

More than 100 compositions have been isolated from the invasive weed species Eupatorium adenophorum Spreng. The chemical compositions in E.adenophorum included terpene, sesquiterpenes,triterpenoids,sterides,flavonids,phenylpropanoids and their derivatives as well. The bioactivities of chemical compositions in E.adenophorum were regarded as insecticidal,antifungal and allelopathic. The chemical compositions and their bioactivities in different the parts of E.adenophorum were reviewed in this paper. It will be useful to research the effeet on biodiversity made by E.adenophorum and develop pilot chemical compounds from E.adenophorum for new bionic pesticide.
