Based on results from 2D NMR studies, both pinoresinol and secoisolariciresinol structures were found to be present in native lignin from spruce wood as well as in spruce kraft lignin and residual kraft pulp lignin. These two structures constitute the major types of beta-beta inter-unit linkages present in spruce lignin, but their formation in the lignin polymer may follow different pathways leading to their different bonding patterns with the rest of the lignin polymer. The mechanisms involved are discussed.
基于二维核磁共振研究结果，发现松脂醇和开环异落叶松脂醇结构存在于云杉木的天然木质素中，以及云杉硫酸盐木质素和残余硫酸盐纸浆木质素中。这两种结构构成了云杉木质素中主要的β-β单元间连接类型，但它们在木质素聚合物中的形成可能遵循不同途径，导致它们与木质素聚合物其余部分的键合模式不同。文中讨论了其中涉及的机制。
