Testing sample selection criteria and loss of biomarkers during cleaning of archaeological unglazed pottery to maximize organic residue quantities

Archaeometry, Volume 67, Issue 3, Page 536-551, June 2025.
Abstract As the number of studies in organic residue analysis (ORA) of ancient pottery—a sensitive but as of today also a destructive method—increases, archaeologists are interested in knowing which samples promise the biggest abundance of analytes in order to avoid unnecessary loss of artefacts.

Synthesis, function, and genetic variation of sorgoleone, the major biological nitrification inhibitor in sorghum

Crop Science, Volume 65, Issue 3, May/June 2025.
Abstract Sorghum is the third most important food crop, grown on nearly 40 million ha globally, and is known for its resilience under unfavorable conditions. Sorghum is reported to have a strong biological nitrification inhibition (BNI) capacity in root systems, a plant function that suppresses soil nitrifier activity, which in turn prevents the ...

Supplementation with Pentadecylresorcinol to a High-Fat Diet Increases the Predicted Representation of Enzymes and Metabolic Pathways for Vitamin B12 Synthesis by the Gut Microbiota Of C57bl6 Mice

Ожирение и метаболизм
5-Pentadecylresorcinol (C15) is a natural alkylresorcinol that has been shown to protect against complications caused by imbalanced nutrition. Although the exact mechanisms of beneficial activity of C15 are not known, we assume that the protective ...

Alkylresorcinol Derivatives and Sesquiterpene Lactones from Cichorium spinosum

Journal of Agricultural and Food Chemistry, 2003
One new alkylresorcinol derivative, cichoriol B, and a mixture of three other ones, cichoriols A, C, and D, were isolated from the dichloromethane extract of Cichorium spinosum, a plant that is used traditionally in the Cretan diet. The methanol extract afforded one new sesquiterpene lactone, (4R)-3,4-dihydrolactucopicrin.

Brewer's spent grain: Unveiling innovative applications in the food and packaging industry

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 3, May 2025.
Abstract Brewer's spent grain, a byproduct of beer brewing, is often discarded as waste, leading to environmental concerns. However, the growing interest in sustainability and the circular bioeconomy has prompted research into its use in food and packaging industries.

Alkylresorcinols in rye (Secale cereale L.) grains. II. Dependence of alkylresorcinols level on weight and specific weight of grains

Acta Societatis Botanicorum Poloniae, 2015
A relation was found between the alkylresoroinols content and the weight of single grains, their specific weight and situation in the ear. In the group of grains with high specific weight (above 1.300 g/cm3) the relative alkykesorcinols content proved to

n-Alkylresorcinol Occurrence in Mercurialis perennis L. (Euphorbiaceae)

Zeitschrift für Naturforschung C, 2010
Investigation of the dichloromethane extracts from herbal and root parts of Mercurialis perennis L. afforded a mixture of 11 homologous n-alkylresorcinols (ARs) with saturated odd-numbered alkyl side chains (C15:0-C27:0). In addition to three predominant ARs (C19:0, C21:0 and C23:0), a number of minor ARs were identified by use of LC-MS/MS and GC-MS ...

Isolation and characterization of synthesis intermediates and side products in hexahydrocannabiphorol

Drug Testing and Analysis, Volume 17, Issue 4, Page 531-543, April 2025.
A commercially purchased hexahydrocannabiphorol (HHCP) sample for recreational use was analyzed by GC‐MS. In addition to the declared (9R)‐ and (9S)‐HHCP, the chromatogram showed a large number of isomeric compounds and other impurities, six of which, including (9R)‐HHCP, were isolated and their structure elucidated using various NMR techniques and GC ...

New criteria for the molecular identification of cereal grains associated with archaeological artefacts

Scientific Reports, 2017
The domestication and transmission of cereals is one of the most fundamental components of early farming, but direct evidence of their use in early culinary practices and economies has remained frustratingly elusive.

Alkylresorcinols in rye (Secale cereale L.) grains. V. Chromatographic analysis of 5-n-alk(en)ylresorcinols during their preparation

Acta Societatis Botanicorum Poloniae, 2014
Analysis of 5-n-alk(en)ylresorcinols during the coarse of their preparation from rye grains showed that changes of the composition of 5-n-alkylresorcinol homologues in acetone oil; raw preparation, and alkylresorcinol fraiction obtained after ...
