| 内容記述 | The condensation degrees of protolignins in 12 species of softwoods, and its variation within the trunk of 30-year-old Hinoki<special>（Chamaecyparis obtusa Endl.）</special> were discussed, using the phenyl nucleus-exchange method. The phenyl nucleus-exchange method is a novel degradation method for lignin allowing the C-C linkages between side chains and phenyl nuclei to be cleaved selectively and almost quantitatively. The procedures in this method are simple, and based on the products, information on the condensation degree of protolignin is rapidly obtained without isolating lignin. The variation of condensation degree of protolignin in horizontal sequence within the trunk of 30-year-old Hinoki was approximately similar at each height, in which it increased slightly once from bark side to pith, then exhibited a minimum value at the sapwood/heartwood boundary section, and increased again in heartwood. On the other hand, the variation of condensation degeen in oblique sequence, which is the succession from the top downwards of the sections fromed in the same years, was less on the whole, compared with that in horizontal sequence. The condensation degrees in 12 species of softwoods were close one another. | |||||||||||||
