Abstract

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was used to investigate the distribution of inorganic elements and a heartwood compound, hinokinin, in discolored ancient woods of hinoki cypress derived from Sanjusangen-do and Horyuji Temple. The tendency of the distribution of hinokinin in the heartwood was similar for the ancient woods and a wood sample freeze-preserved immediately after cutting. In contrast, the distributions of the inorganic ions in the ancient woods were inconsistent with those of the freeze-preserved wood, as the concentrations of the inorganic ions, Na, K, and Ca were higher in the sapwood than in the heartwood of the ancient woods. The result suggests that the concentrations of the inorganic elements in the heartwood and sapwood were altered during the long-term drying process in the ancient woods. The TOF-SIMS analysis also showed that detecting the distribution of the inorganic ions is useful to distinguish the sapwood from heartwood in dendrochronological dating of ancient woods.
