近年来,国内外对天然二聚化合物和它们单体部分的生物活性以及构—效关系进行研究,发现二聚化合物的生物活性往往超过它们相应单体部分的活性。本文笔者概述了天然二聚化合物的概念,在植物界的分布,化学结构类型及其生物活性,为进一步开发利用天然二聚化合物提供科学依据。 In recent years, studies on the biological activity and the structure-effect relationship of natural dimeric compounds and their monomeric components have been conducted both at home and abroad, and it has been found that the biological activities of dimeric compounds tend to exceed the activities of their corresponding monomeric moieties. In this paper, the author summarizes the concept of natural dimeric compounds, distribution in the plant kingdom, types of chemical structures and their biological activities, and provides scientific basis for the further development and utilization of natural dimeric compounds.
