摘　　要：在海洋环境中,许多海洋生物都能产生对环境无危害的、具有防污活性的次生代谢产物以保护自身的洁净,利于自身的生存.用化学生态学的方法从海洋生物中提取天然防除物质成为近年来解决海洋污损生物问题的新思路,其目标是寻找高效无毒的防污材料取代原有的对海洋环境有严重危害的化学合成防污材料.虽然目前对提取生物的次生代谢产物的防污机理还所知甚少,但不少从海洋生物中获得的天然产物已显示出良好的防污活性.要解决污损生物防污问题,还需对天然产物的作用机制、生态学效应、天然产物与涂料的结合、控制和释放及野外实验进行更加深入的研究与探讨.Many marine organisms can produce secondary metabolites beneficial to the protection of marine environments against fouling, and thus, applying chemo-ecological methods to extract the natural antifoulants from marine organisms to resolve the problems relevant to marine fouling is a new thinking in resent years. Its aim is to search for high efficient and non-toxic antifoulants to replace the existing chemically synthetic ones which are unfortunately found to have widespread toxic effects on marine environment. Although we know few about the antifouling mechanisms of secondary metabolites, many natural products have been proved to have antifouling activity. Therefore, basic and applied researches on the ecological roles of these natural compounds, their action mechanisms, coating compatibility, controlled release, and field test are required in the future.
