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

Plant Resins—Their Formation, Secretion and Possible Functions
, 1979 Plant resins pose interesting ecological, taxonomic, physiological, and biochemical problems. This chapter briefly describes the resins in chemical terms and presents their contrast with certain other plant products. Resins are nonvolatile products of plants, from which they exude naturally (surface resins) or can be obtained by incision or infection ...

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).

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. They were also taken up by anion exchangers. Among them Dowex 1-X8 was found to show the strongest effect
