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

Resin glycosides from Convolvulaceae plants [PDF]
Journal of Natural Medicines, 2017 Resin glycosides are well known as purgative ingredients, which are characteristic of certain crude drugs such as Mexican Scammony Radix, Orizabae Tuber, and Jalapae Tuber, all of which originate from Convolvulaceae plants. Depending on their solubility in ether, these are roughly classified into two groups-jalapin (soluble) and convolvulin (insoluble).
