Plant Resins-Chemistry, Evolution Ecology and Ethnobotany [PDF]

open access: yesHortScience, 2005
Plant resins are often something ornamental horticulturists either ignore or endure-particularly when they clog up pruners. This book gives a different view-a rhyme and reason as to why plants produce resins and how generations of people have used resins for economic or personal benefit.

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

open access: yesHealth 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.

Species-level determination of closely related araucarian resins using FTIR spectroscopy and its implications for the provenance of New Zealand amber [PDF]

open access: yesPeerJ, 2015
Some higher plants, both angiosperms and gymnosperms, can produce resins and some of these resins can polymerize and fossilize to form ambers. Various physical and chemical techniques have been used to identify and profile different plant resins and have

Tree resin composition, collection behavior and selective filters shape chemical profiles of tropical bees (Apidae: Meliponini). [PDF]

open access: yesPLoS ONE, 2011
The diversity of species is striking, but can be far exceeded by the chemical diversity of compounds collected, produced or used by them. Here, we relate the specificity of plant-consumer interactions to chemical diversity applying a comparative network ...
