A reverse trend was also observed between the yield of phenolic compounds and the ratio of phenolic acid/aldehyde ratio.

抄録
内容記述 A histosol profile at Tsukude in central Japan has the age of ca. 32,000 yBP and records a history of Holocene and Pleistcene periods in the composition of organic and inorganic components in it. We have determined C and N contents and compositions of phenolic and lipid compounds along with ^<14>C-ages of important layers, and considered the implication of the change in their compositions with age in relation to the climatic changes and the topographic changes around the wet land. The ratio of C/N and compositions of phenolic and lipid compounds were very stable in peat layers formed during the last glaciation maximum (20,000-30,000yBP). During the age of post-glacial warming and frequent volcanic explosions, the C/N ratio increased and the contents of phenolic and lipid compounds decreased, while the phenolic acid/aldehyde ratio increased, indicating that decomposition and humification of peaty material was enhanced in this age. A reverse trend was also observed between the yield of phenolic compounds and the ratio of phenolic acid/aldehyde ratio. Long chain fatty acids with chain length from 16 to 30 were detected in the peat, where the yield of montanic acid (C28) was largest. The shorter the chain length, the more unstable the fatty acids were. Yields and ratios of fatty acids seemed to reflect the environmental conditions in which each peat layers were formed.
