中文摘要:漆酚是漆树科植物独有的化学成分,具有良好的抗氧化、抗肿瘤、抗病毒等生物活性,极具药物和工业生产开发价值。该研究通过对国内外有关漆树科各类群有关漆酚数据的搜集和整理,开展漆树科漆酚的多样性与分布情况的综合统计;同时在利用核基因ETS和叶绿体基因rps16和trnL F重建漆树科系统发育树的基础上,探讨漆酚在漆树科及各属间的起源和演化关系。结果表明:(1)漆树科漆酚具有较高的多样性,在其苯环和 R链上都有很大的变异。(2)发现漆酚仅存在于Anacardioideae亚科中,是该亚科的一个重要界定特征。(3)基于漆酚苯环结构和 R链特征的祖先性状重建分析表明,漆树科的漆酚是由邻苯二酚向间苯二酚演化,而漆酚 R链的十五烃(烯)基则是向十七烃(烯)基平行演化。

Diversity and Evolution of Urushiol in Anacardiaceae
Abstract:Urushiol is a unique biochemical component in Anacardiaceae, which has excellent biological activities in anti oxidation, anti tumor and anti virus, and then has great values in the development of pharmaceutical and industrial production. In this study, comprehensive statistic analyses on the diversity and distribution of urushiol in the family were carried out based on urushiol data of different groups of Anacardiaceae extracted from literatures. Meanwhile, the origin and evolution of urushiol in the family were inferred using the nuclear ETS and the chloroplast genes rps16 and trnL F sequences. The results show that: (1) the urushiol has a high diversity and has great variation in its phenol and R chain. (2) Urushiol is only found in the Anacardioideae and is an important feature of the subfamily. (3) Reconstruction analysis of ancestral traits based on the structure of urushiol phenol and R chain indicates that urushiol from the lacquer family evolved from catechol to resorcinol, while the pentadec(en)yl group of urushiol R chain evolved to the heptadec(en)yl group.
