木脂素是苯丙素类二聚体，其中苯丙素单元通过其侧链的中心碳（C8）连接。配体在氧化水平、取代模式和它们的基本碳框架的化学结构方面变化很大。除了结构多样性，木脂素在对映体组成、生物合成和系统发育分布方面显示出相当大的多样性。本文综述了木脂素类化合物的分类学特征，并列出了66种典型木脂素类化合物的系统发育分布。缩写：SIRD -开环异落叶松树脂醇脱氢酶; PLR -松醇落叶松树脂醇还原酶; DP - dirigent蛋白
Lignans are phenylpropanoid dimers, where the phenylpropane units are linked by the central carbon (C8) of their side chains. Ligans vary substantially in oxidation level, substitution pattern, and the chemical structure of their basic carbon framework. In addition to structural diversity, lignans show considerable diversity in terms of enantiomeric composition, biosynthesis, and phylogenetic distribution. In this review, these diversities are outlined and the phylogenetic distribution of plants producing 66 typical lignans is listed. The distribution is correlated with the putative biosynthetic pathways of the lignans and discussed from evolutionary aspects.Abbreviations:SIRD – Secoisolariciresinol dehydrogenase; PLR – pinoresinol lariciresinol reductase; DP – dirigent protein
