“…The dolabralexin precursor, dolabradiene, was reported previously in only a few coniferous trees of the Araucariaceae and Cupressaceae families (Brophy et al, 2000;Takahashi et al, 2001), and its biological role in these species is unknown. Thus, based on current knowledge and the absence of dolabralexin in other major Poaceae crops, such as rice and wheat, the inferred emergence of the dolabralexin biosynthetic pathway occurred after the evolutionary separation of maize from wheat and rice approximately 50 million years ago (Wolfe et al, 1989;Grass Phylogeny Working Group II, 2012).…”

“…Compounds, like pinene, thujene and limonene are widespread in most Araucariaceae species (Brophy et al, 2000). They represent the major components of araucarian essential oils (Brophy et al, 2000;Staniek et al, 2010). Furthermore, owing to their lower molecular weight, these chemicals are generally highly volatile and not readily preserved in sediments.…”

“…These chemicals are mainly represented by unsaturated hydrocarbons, alcohols and acids, constituents of essential oil and resins (e.g. Pietsch and König, 2000;Brophy et al, 2000). However, they are common in conifers as well as in other plants like angiosperms and bryophytes (Otto and Wilde, 2001).…”

“…Tetracyclic diterpenoids belong to the beyerane, kaurane, phyllocladane, trachylobane and atisane types (Brophy et al, 2000;Otto and Wilde, 2001). According to Thomas (1969), Brophy et al (2000) and Pietsch and König (2000), both tri-and tetracyclic diterpenoids are synthesized as unsaturated hydrocarbons (like pimaradienes, abietadienes, kaurenes, etc. ), acids (like abietic and isopimaric acids) and more rarely as alcohols (like phyllocladanol and phenolic abietanes, which are only reported in few Agathis species) in Araucaraiceae species.…”

“…Distribution of bioterpenoids varies from one species to another in fresh plants (Thomas, 1969;Brophy et al, 2000). For instance, each species seems to be dominated by one or possibly two compounds.…”

Twelve species of the conifer family Araucariaceae, including Araucaria (6 species), Agathis (3 species) and Wollemia (1 species) genera, were submitted to artificial maturation by confined pyrolysis. The aim of these experiments is to transform the biomolecules synthesized by these species into their homologous geomolecules in laboratory conditions. Determination of the diagenetic molecular signatures of Araucariaceae through experimentation on extant representatives allows us to complete our knowledge in botanical palaeochemotaxonomy. Such knowledge is relevant to palaeoenvironmental, environmental and archaeology purposes. All artificially diagenetic species of Araucariaceae are firstly characterized by a predominance of saturated tetracyclic diterpenoids including ent-beyerane, phyllocladanes and ent-kauranes. Moreover, Araucaria genus shows a high relative abundance of bicyclic sesquiterpenoids, particularly the cadalane-type compounds accompanied by those of eudesmane and bisabolane types as well as chamazulene and pentamethyl-dihydroindenes. Diterpenoids are of labdane, isopimarane and abietane types (essentially derived from abietanoic acids) as well as isohexyl alkylaromatic hydrocarbons. Compared to the tetracyclic diterpenoids, these compounds show a relatively lower abundance, reaching trace levels in the case of saturated abietanes. Distributions of sesquiterpenoids and diterpenoids of Agathis show some similarities to that of Araucaria, with the exception of one species, in which the tetracyclic compounds are absent and the abietane type (essentially derived from abietanoic acids) predominant. High similarities between the Wollemia and Araucaria genera are observed. Both are characterized by some high relative abundance of tetracyclic compounds with no predominance of other specific diterpenoids
