Lignans are particularly interesting secondary metabolites belonging to the phenyl-propanoid biosynthetic pathway. From the structural point of view, these molecules could belong to the aryltetralin, arylnaphtalene, or dibenzylbutyrolactone molecular skeleton. Lignans are present in different tissues of plants but are mainly accumulated in seeds. Extracts from plant tissues could be characterized by using the NMR-based approach, which provides a profile of aromatic molecules and detailed structural information for their elucidation. In order to improve the production of these secondary metabolites, elicitors could effectively stimulate lignan production. Several plant species are considered in this review with a particular focus on species, well recognized as the main producer of lignans.

木脂素是苯丙素生物合成途径中具有特殊意义的次生代谢产物。从结构的角度来看，这些分子可能属于芳基四氢萘、芳基萘或二苄基丁内酯的分子骨架。木脂素存在于植物的不同组织中，但主要积累在种子中。植物组织提取物可以用基于 NMR 的方法进行表征，该方法可以提供芳香族分子的图谱，并详细阐明其结构信息。为了提高这些次生代谢产物的产量，可以使用诱导子有效地刺激木脂素的产生。本文综述了几种被认为是木脂素主要生产者的植物物种，特别是物种。
