The tetra methyl ammonium hydroxide (TMAH) method has advantages of low consuming of time and sample in comparison with the other chemical analysis methods of organic compounds such as the alkaline CuO oxidation method. In this study, I aimed at a basic investigation for high resolution analysis of paleo-climatic changes by the TMAH method, with using the marine sediment of California offshore which obtained by the Leg 167, Site 1017 of ODP (Ocean Drilling Program). As a result, with the TMAH method we can analyze many organic compounds in the marine sediment, such as cutin acids, ω-hydroxy acids, dicarboxylic acids, β-hydroxy acids, alcohols, and phytol beside lignin phenols and fatty acids. Therefore, this method is valuable for a high-resolution analysis of paleo-climatic changes.
