Fifty-one and nineteen compounds were detected respectively from the volatile extracts from the fossils of Miocene leaves of Metasequoia glyptostroboides and early Cretaceous seed cone of Pityostrobus spp. by gas chromatography-mass spectrometry (GC-MS) analysis. These compounds were found belonging to n-alkanes, n-alkenes, n-alkanols, long chain fatty acids and their esters, phthalates, terpenoids and aromatic compounds, and three compounds of them, abietane diterpenoid, heptadecanoic acid and retene were considered as biomarkers for gymnosperm plants.
