Metabolomics reveals the origins of antimicrobial plant resins collected by honey bees. [PDF]

PLoS ONE, 2013
The deposition of antimicrobial plant resins in honey bee, Apis mellifera, nests has important physiological benefits. Resin foraging is difficult to approach experimentally because resin composition is highly variable among and between plant families ...

Adsorption of plant phenols by polystyrene resins

Acta Societatis Botanicorum Poloniae, 2014
Adsorption of nine plant phenols by nine polystyrene ion-exchange resins was investigated in an experimental model system. The phenols were adsorbed by Amberlite CG-120 more efficiently than any other acidically charged resins tested in this study.

Racemic Norlignans as Diastereoisomers from Ferula sinkiangensis Resins with Antitumor and Wound-Healing Promotion Activities

Molecules, 2022
Ferulasinkins A–D (1–4), four new norlignans, were isolated from the resins of Ferula sinkiangensis, a medicinal plant of the Apiaceae family. All of them were obtained as racemic mixtures, chiral HPLC was used to produce their (+)- and (−)-antipodes ...

Experimental induction of resins as a tool to understand variability in ambers [PDF]

Fossil Record, 2021
Amber is chiefly known as a preservational medium of biological inclusions, but it is itself a chemofossil, comprised of fossilised plant resin. The chemistry of today's resins has been long investigated as a means of understanding the botanical sources ...

Pinoresinol stimulates keratinocyte proliferation and downregulates TNF‐α secretion in peripheral blood mononuclear cells: An experimental in vitro study

Health Science Reports, 2023
Background and Aims Natural coniferous resins are used in traditional medicine for the treatment of skin wounds. Coniferous wood resins (“callus” resin) are a mixture of abietic (resin) acids, lignans such as pinoresinol, and p‐coumaric acid.

Transition of plant resins from the biosphere to the lithosphere

Geo&Bio, 2020
In the article the authors consider in detail the process of transition of plant resins from the biosphere to the lithosphere, characterize the conditions and paleogeographic situation of such transition, the formation of deposits of resin minerals and ...
