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

Reduction of the formaldehyde content in leathers treated with formaldehyde resins by means of plant polyphenols [PDF]
Formaldehyde has applications in many industrial processes, including synthesis of resins and syntans to be used in the retanning process of leather. When resins are employed, they can hydrolyse, releasing formaldehyde.

Adsorption of plant phenols by polystyrene resins
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.

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