“…Ferruginol, 6,7-dehydroferruginol, sugiol, 7α-p-cymenylferruginol, chamaecydin, iso -chamaecydin, and 6β-hydroxychamaecydin were present as generally significant components in the resins of all four species (Table 2). These natural products are stable and have been reported in environmental and fossil samples [7,8,11,14,54,64,65,77].…”

“…Natural products, especially terpenoids or their derivatives, are preserved in the ambient environment or geological record. When extracted and characterized by gas chromatography-mass spectrometry (GC-MS) they are used by organic geochemists as tracers for sources, transport and alteration processes of organic matter in any global compartment [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]. The application of GC-MS in the analysis of natural product mixtures extracted from plants for compound characterization can also be of utility for rapid screening in pharmacological studies [16].…”

“…Structure determinations and pharmacological potential studies of resin terpenoids isolated and purified from species of the Taxodioideae subfamily have been reported by numerous chemists and pharmacologists [24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42]. However, the connection of the known natural products isolated from these conifers with their application as tracers in other interdisciplinary sciences has been limited [7,8,14,43]. This is due to the lack of reports on the chemical compositions of the total resin mixtures, and the paucity of mass spectra for known compounds, especially the oxygenated natural products.…”

The resins bled from stems and in seed cones and leaves of Cryptomeria japonica, Glyptostrobus pensilis, Taxodium distichum, and T. mucronatum 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., n-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.

“…Natural products from plants (e.g., terpenoids of conifer resins) are preserved directly or as derivatives (diagenetic products) in the contemporary and fossil geological environments. When extracted and characterized, they are used as molecular biomarkers in organic geochemistry, paleontology, forensics, archeology, and environmental chemistry for source identification [1,2,3,4,5,6,7,8,9,10,11,12,13,14]. The application of gas chromatography-mass spectrometry (GC-MS) in the analysis of natural product mixtures extracted from plants for compound characterization can also be of utility for rapid screening in pharmacological studies [15].…”

The environmental fate of conifer resins and their natural product compounds as mixtures is of importance for source, alteration, and transport studies. The compound compositions of resins of the common Callitris species (Cupressaceae) based on gas chromatography-mass spectrometry have not been reported. Results show that diterpenoids were the most abundant components and callitrisic acid was present in the resin extracts of all Callitris species analyzed. Significant amounts of 4-epi-pimaric and sandaracopimaric acids, with lesser communic, ozic, and lambertianic acids, were also in the mixtures. Phenolic diterpenoids, for example, ferruginol, hinokiol, were found in trace quantities in some samples. Thus, callitrisic acid and 4-epi-pimaric acid are the characteristic diterpenoids of Callitris species that are amenable to molecular biomarker analyses in geological or environmental applications.

“…The aim of the present study is to characterize the palaeoenvironmental conditions and organic matter (OM) sources of a mudstone—lignite core log from Troyanovo‐1 Mine of MIB using biomarker analysis. Previously, the lignite samples were studied (Stefanova, Simoneit, Marinov, Zdravkov, & Kortenski, 2016) concerning novel polar biomarkers. An attempt to match mudstone data with enriched and renewed lignite ones is done.…”

A sequence of three lignite seams and interlayering carbonaceous mudstone is characterized by geochemical proxies. The study is extended by the palaeoenvironmental details given by the fossil fauna (gastropods, ostracods, and fishes). The predominant minerals (quartz and kaolinite) and main oxide relations of the carbonaceous mudstone point to sand and clay washed from weathered and/or altered felsic rocks from the catchment area. The mudstone features to deposition from suspension in standing or slow to persistently moving fresh waters at the bottom of the core log, and slightly aerated, warm, fresh to low saline, acidic to alkaline waters on the top. Three communities of organisms are depicted. The first is the pre‐swamp environment characterized by standing or slow moving fresh waters and detrital organic matter deposition. The second is the environment of swamp of detrital forest trunks. Depending on the climate and water table, the main forest communities are of trees of families Cupressaceae, Taxodiaceae, and Podocarpaceae accompanied by trees of family Betulaceae, and herbaceous plants. Different Sphagnum species are also abundant. The dry/cold environment is reflected in the herbaceous organic matter deposition. Polar terpenoids ratio differentiates slight climatic oscillations for the samples with a strong Gymnospermae dominance. The second coal seam development reflects the optimum tectonic conditions for peat growth in a cold and dry climate leading up to 25 m lignite deposition. The third is the moss swamp environment with very fluctuating elements. At the top of the log, a Sphagnum‐dominated peat has developed.
