采用碱性硝基苯氧化法、酸解法和臭氧氧化法对卷柏科8种原始维管植物的木质素化学结构进行了表征。从日本东京大学千叶的大学林中采集到卷叶卷柏、卷柏、疏叶卷柏; involvens、黄根卷柏（Selaginella chrysorrhizos）和未鉴定的卷柏属（Selaginella sp.）收集自泰国北方。本研究中所检测的所有卷柏属植物的木质素都富含卷柏基核。研究表明，卷柏木质素中有相当一部分的双辛烯基核形成了双辛烯基甘油-β-芳基醚单体间键。卷柏木质素的芳基甘油-β-芳基醚单体间键的主要非对映异构体是具有被子植物木质素特征的赤型。此外，S. involvens，S. tamarycina和S.从日本东京大学千叶的大学森林中采集的疏叶木（remotifolia），根据Bjorkman的方法进行分离，并对木质素的结构特征进行光谱分析。初步确定了原始蕨类植物卷柏属植物的木质素为典型的愈创木基-胡萝卜基型木质素，与被子植物木质素相似。
The lignin chemical structures of eight species of the Selaginella family, which are primitive vascular plants, were characterized by alkaline nitrobenzene oxidation, acidolysis, and ozonation. Selaginella involvens, Selaginella tamariscina, and Selaginella remotifolia were collected from the University Forest in Chiba, the University of Tokyo, Japan, and Selaginella biformis, Selaginella pennata, S. involvens, Selaginella chrysorrhizos, and unidentified Selaginella species (Selaginella sp.) were collected from northern Thailand. Lignin of all Selaginella species examined in this study was rich in syringyl nuclei. It was confirmed that a considerable portion of syringyl nuclei of Selaginella lignin formed syringylglycerol-beta-aryl ether intermonomer linkages. The major diastereomer of arylglycerol-beta-aryl ether intermonomer linkages of Selaginella lignins was the erythro-form exhibiting angiosperm lignin characteristics. In addition, lignins of S. involvens, S. tamariscina, and S. remotifolia collected from the University Forest in Chiba, the University of Tokyo, Japan, were isolated according to Bjorkman's procedure, and structural features of the lignins were spectrometrically analyzed. It was confirmed that lignin of Selaginella species, which are primitive pteridophytes, was typical guaiacyl-syringyl type as well as being similar to angiosperm lignin.
