摘　　要：卫矛科植物苦皮藤CelastrusangulatusMax.是我国著名的杀虫植物,自1980年代以来,已从化学和生物学的角度对这一杀虫植物进行了多学科的交叉研究。该文综述了苦皮藤中化合物的主要生物活性,包括对昆虫的拒食作用、毒杀作用、麻醉作用,对植物病菌的杀菌作用以及抗癌活性。就主要杀虫成分的杀虫作用机理,特别是对苦皮藤素Ⅳ可能作用于昆虫神经-肌肉突触、苦皮藤素Ⅴ作用于昆虫消化系统以及在中肠肠壁细胞膜上可能存在有苦皮藤素Ⅴ受体的研究进行了总结。此外,还综述了苦皮藤素制剂的应用技术和环境毒理学的有关研究。最后,分析和讨论了这些研究中存在的问题及其发展前景。Chinese bittersweet, Celastrus angulatus Max., is a traditional insecticidal plant in China. Since 1980s, the insecticidal plant has been investigated by multi-subjects crossed research in the world. This paper reviews the bioactivities of the compounds from the plant in five aspects, including insect antifeedant action, insecticidal action, insect narcosis, fungicidal action and anticancer action. The advances of the research on the insecticidal mechanisms of major component celangulin Ⅳ and Ⅴ from the plant are summarized. It is elucidated further that celangulin Ⅳ could target the neuromuscular synapse on the insect, but the celangulin V is believed to act on the insect digestive system, and it is predicted that there could be receptors on plasmelemma and organelle membrane of the midgut cells of pest larva. The paper also reviews the field application technology and environment toxicology of the celangulin preparations. Finally, the present problems and the future prospect are discussed.
