| Summary: | The resins bled from stems and in seed cones and leaves of <i>Cryptomeria japonica, </i><i>Glyptostrobus</i><i> </i><i>pensilis</i>,<i> Taxodium distichum</i><i>,</i><i> </i>and<i> </i><i>T. </i><i>mucronatum</i><i> </i>were characterized to provide an overview of their major natural product compositions. The total solvent extract solutions were analyzed as the free and derivatized products by gas chromatography-mass spectrometry to identify the compounds, which comprised minor mono- and sesquiterpenoids, and dominant di- and triterpenoids, plus aliphatic lipids (e.g., <i>n</i>-nonacosan-10-ol). Ferruginol, 7α-p-cymenylferruginol, and chamaecydin were the major characteristic markers for the Taxodioideae conifer subfamily. The mass spectrometric data can aid polar compound elucidation in environmental, geological, archeological, forensic and pharmaceutical studies.
