植物酚类化合物是由莽草酸-苯丙素类化合物-黄酮类化合物代谢途径产生的次生代谢产物。植物需要酚类化合物用于色素沉着、生长、繁殖、抵抗病原体和许多其他功能。因此，它们代表了已经受到自然通信/重印请求的适应性特征：Prof. Lattanzio，Dipartimento di Scienze Agro-Ambientali，Chimica e Difesa Vegetale，Universita degli Studi di福贾，71100-福贾，意大利。E-mail：v.lattanzio@ unifg.it Lattanzio et al. 24进化过程中的选择。植物比动物合成更多的次级化合物，因为它们不能依靠身体的移动来逃避捕食者，因此进化出了对抗捕食者的化学防御。本文简要介绍了植物酚类化合物作为紫外线防护剂、信号物质、色素、内部生理调节剂或化学信使的研究进展，并探讨了酚类化合物在植物抗真菌病原菌和植食性昆虫机制中的作用。
Plant phenolics are secondary metabolites that encompass several classes structurally diverse of natural products biogenetically arising from the shikimate-phenylpropanoids-flavonoids pathways. Plants need phenolic compounds for pigmentation, growth, reproduction, resistance to pathogens and for many other functions. Therefore, they represent adaptive characters that have been subjected to natural Correspondence/Reprint request: Prof. Vincenzo Lattanzio, Dipartimento di Scienze Agro-Ambientali, Chimica e Difesa Vegetale, Universita degli Studi di Foggia, 71100-Foggia, Italy. E-mail: v.lattanzio@unifg.it Vincenzo Lattanzio et al. 24 selection during evolution. Plants synthesize a greater array of secondary compounds than animals because they cannot rely on physical mobility to escape their predators and have therefore evolved a chemical defence against such predators. This article, after a short review of plant phenols and polyphenols as UV sunscreens, signal compounds, pigments, internal physiological regulators or chemical messengers, examines some findings in chemical ecology concerning the role of phenolics in the resistance mechanisms of plants against fungal pathogens and phytophagous insects.
