N-Alkanes in Permafrost Peatlands [PDF]
PlantsIn this study, high-performance liquid chromatography (HPLC) methods were utilised to identify and quantify C21–C33 n-alkanes in permafrost peatlands located within the Eastern European and Western Siberian cryolithozone.

Decoupling Distribution of n-Alkanes in Aeolian Sand and Vegetation of the Northern Ulan Buh Desert, China: Insight into Organic Matter Preservation in Arid Regions [PDF]
PlantsFallen leaves and their decomposition directly deposit leaf wax n-alkanes into sediments, which can be used to identify local flora. These n-alkanes are important for studying past vegetation and climate, but their distribution in sediments must be known.

Quantitative and Qualitative Evaluation of Plant Intake in Laying Hens: n-Alkanes as Predictive Fecal Markers for Dietary Composition Assessment [PDF]
AnimalsThe shift in animal welfare standards towards free-range housing for laying hens in the EU has raised questions about changes in dietary composition. Accurate assessment of outdoor plant material intake is crucial for effective feeding strategies.

Measuring long chain alkanes in diesel engine exhaust by thermal desorption PTR-MS [PDF]
Atmospheric Measurement Techniques, 2014 A method using thermal desorption sampling and analysis by proton transfer reaction mass spectrometry (PTR-MS) to measure long chain alkanes (C12–C18) and other larger organics associated with diesel engine exhaust emissions is described.

Evaluation of n-alkanes and their carbon isotope enrichments (δ13C) as diet composition markers
Animal, 2011 Plant cuticular n-alkanes have been successfully used as markers to estimate diet composition and intake of grazing herbivores. However, additional markers may be required under grazing conditions in botanically diverse vegetation.

Nonacosan-10-ol and -Alkanes in Leaves of
Natural Product Communications, 2020 In leaf cuticular wax of Pinus pinaster, content of nonacosan-10-ol is high (77.1% on average). n -Alkanes ranged from C 18 to C 35 with the most dominant C 29 (24.8%).

Age and origin of leaf wax n-alkanes in fluvial sediment–paleosol sequences and implications for paleoenvironmental reconstructions [PDF]
Hydrology and Earth System Sciences, 2020 Leaf wax n-alkanes are increasingly used for quantitative paleoenvironmental reconstructions. However, this is complicated in sediment archives with associated hydrological catchments since the stored n-alkanes can have different ages and origins.

In vitro studies of the metabolism of [14C]-n-alkanes using ruminal fluid of sheep as substrate
Animal, 2008 Whether the rumen microbes are able to synthesize and/or degrade long-chain alkanes in anaerobic conditions remains a question to be answered before these hydrocarbons can be confidently used as duodenal flow or rumen transit markers. In this context, an
