Triterpenoids and their derivatives are ubiquitous in sediment samples. Land plants are
major sources of nonhopanoid triterpenoids; these terpenoids comprise a vast number of …

Tricyclic diterpenoids and non-steroid or non-hopanoid pentacyclic triterpenoids are almost
exclusively taxon-specific terrestrial plant biomarkers produced by conifers and …

Tricyclic diterpenoids and pentacyclic triterpenoids are nearly exclusively produced by
gymnosperms and angiosperms, respectively. Even though both classes of terpenoids have …

Plant-derived terpenoids, long recognized as biomarkers, can help reveal the major
taxonomic groups of land plants present in ancient environments, even if rocks and …

Biomarkers, molecular fossils, are organic compounds in Holocene to Precambrian
sedimentary deposits that can be related to specific chemical compounds produced in the …

The vast majority of structurally diverse metabolites play essential roles in mediating the
interactions between plant and environment, and constitute a valuable resource for …

The presence of 7-p-cymenylferruginol and its diagenetic biomarkers occurring in Cenozoic
fossil plants and Mesozoic siltstones and coals has been studied using gas chromatography …

Several oleanane-related triterpenoids bearing a unique C-2 oxygenated functionality have
been identified as the predominant triterpenoids from a 4900 year old oak wood sample …

Plant biomarkers, such as terpenoids and leaf wax components (n-alkanes, n-alkanoic acids
and n-alkanols), are frequently found in sediments and can be used, often in association …

Terpenoid biomarkers with high chemotaxonomic value, which can be used for the
identification of an angiosperm input to sedimentary organic matter are desirable for studies …
