植物缩合单宁对草食动物的抗寄生虫性

Plant Condensed Tannins: Antiparasitic Activity against Internal Parasites in Herbivores

植物缩合单宁广泛存在于众多植物种群,具有抵御动物摄食的化学防卫功能。近年来植物缩合单宁因其抗寄生虫性受到愈来愈多的关注,相关研究为动物肠胃道寄生虫防控提供了新的途径,它有望成为传统化学驱虫剂的替代物质。本文在总结了迄今研究成果的基础上,将植物缩合单宁的抗寄生虫机制归纳为营养免疫假说和代谢阻断假说,并详细阐述了影响植物缩合单宁抗寄生虫性的各种因素。

Plant condensed tannins are widely distributed in the plant kingdom, and have capabilities of chemi- cal defense for ingestion of herbivores. Recent years, many studies have focused on the antiparasitic capabilities of plant condensed tannins which provide a new solution for prevention of parasites infection in herbivores. It is hopeful that condensed tannins become a substitute for anthelmintic in the future. Based on the summarization of research progress, in this paper, the mechanisms of prevention of parasites infection of plant condensed tan- nins for herbivores were generalized to two hypothesizes, which were nutrition immunology hypothesis and metabolic block hypothesis, and the variable factors influencing the capabilities of parasite prevention were re- viewed.
