回顾了过去 15 年人们对单宁的兴趣大幅增长的历史背景。由于对动物（脊椎动物和无脊椎动物）重要的其他因素同时存在，从分类学角度讨论绿色植物中单宁的分布和生态重要性的相关证据特别困难。对化学进行了简要介绍，然后是有关潜在作用模式的一些详细信息，并讨论了植物中单宁的定量评估。单宁对食草动物的生物活性在脊椎动物和节肢动物的单独部分中介绍。单宁似乎对这两组动物都有有害影响，但这些影响可能在脊椎动物中更常见。一些动物的摄食受到抑制，而如果饮食中浓度过高，许多动物的生长也会受到抑制。没有明确的证据表明其作用方式具有抗消化作用。有害影响包括肠道上皮细胞的侵蚀和可水解单宁分解产物的毒性。该综述最后概述和总结了单宁在植物中除防御食草动物之外的潜在作用，以及对研究需求的建议。
The historical background to the interest in tannins, which has increased considerably over the last 15 years, is reviewed. The distribution of tannins in green plants is discussed in taxonomic terms and correlative evidence of ecological importance shown to be particularly difficult because of the co-occurrence of other factors important to animals, both vertebrates and invertebrates. A brief account of the chemistry is followed by some details on the potential modes of action, and the quantitative evaluation of tannins in plants is discussed. The biological activity of tannins on herbivores is covered in separate sections on vertebrates and arthropods. In both groups tannins seem to have detrimental effects, but probably these are more common in vertebrates. Some animals are inhibited from feeding, while many suffer poor growth if high concentrations occur in the diet. There is no definitive evidence for the mode of action being antidigestive. Deleterious effects include erosion of gut epithelia and toxicity from the breakdown products of hydrolyzable tannins. The review concludes with an overview and summary of potential roles of tannins in plants other than in defence against herbivores, and suggestions for research needs.
