Ultrafiltration of Guayule Resin
Journal of Membrane Science, 1995Abstract The ability of ultrafiltration membranes to effect a separation of the volatle essential oil fraction of guayule resin from other volatile constituents is experimentally demonstrated. For a methanol extraction of guayule resin, 200 and 500 molecular weight cut-off cellulose triacetate ultrafiltration membranes produced a permeate rich in ...

Microbial transformation of some triterpenoids of Guayule resin by Chaetomium sp.
Phytochemistry Letters, 2023Microbial biotransformation of argentatin A (1), isoargentatin A (2) and argentatin C (3), the triterpenoid constituents of guayule (Parthenium argentatum) resin was conducted with Chaetomium sp. PA001, an endophytic fungus of the same plant. The experiments yielded six new products (4–9) formed by: (i) nucleophilic oxygenation of the 3-ketone moiety ...

Cutting height effects on guayule latex, rubber, and resin yields
Industrial Crops and Products, 2010Abstract Guayule (Parthenium argentatum Gray) is a perennial shrub native to the Chihuahuan Desert. While guayule traditionally has been cultivated for rubber, more recently it is being cultivated for its hypoallergenic latex. Other uses including termite resistant wood products and as an energy source have also been identified.

Guayule resin in amine—epoxy strippable coatings
Bioresource Technology, 1991Abstract The use of guayule coproducts as plasticizer/ adhesive modifiers in high-performance epoxy resin coatings was investigated. An amine curing agent, Jeffamine D-400, was employed to affect crosslinking. Epoxy resin coatings with and without guayule modification were applied to treated and untreated steel and aluminum panels for performance ...

The efficacy of guayule resin as a pesticide
Bioresource Technology, 1991Abstract Researchers from the United States are evaluating the nonrubber-producing extract (resin) of the guayule bush (Parthenium argentatum Gray) as a potential wood protectant against marine and terrestrial wood-destroying organisms in Panama. Wood treated with guayule resin was not attacked, or only lightly attacked, by limnorians (crustacean ...

Degradative Effects of Guayule Resin on Natural Rubber
Rubber Chemistry and Technology, 1981Abstract This study indicates that the degradative effects of guayule resin on natural rubber are due to the presence of unsaturated fatty acids in the resin. Since linoleic acid is, by far, the most abundant unsaturated fatty acid in guayule resin, it appears that linoleic acid is primarily responsible for the degradative effects of guayule ...

The leachability of guayule resin from treated wood
Industrial Crops and Products, 1993Abstract Field evaluation has shown that guayule resin has potential as a protectant for wood against damage by terrestrial wood-destroying organisms. When used in this capacity, it is essential to know whether the resin migrates from the wood, as a contaminant, into the natural environment.

Industrial Crops and Products, 2021
Abstract Guayule (Parthenium argentatum Gray) is a perennial shrub of the Asteraceae family native to the arid southwestern U.S. and northern Mexico that produces high-quality, hypoallergenic natural rubber. Guayule processing produces three output streams: high-molecular weight rubber as the primary product, a mixture of resin/low-molecular weight ...

Rubber and Resin Yield Performance of New Guayule Selections
Agronomy Journal, 1992AbstractGuayule (Parthenium argentatum Gray) is a promising alternative to the rubber tree (Hevea brasiliensis Muell. Arg.) for domestic production of natural rubber in semiarid regions. Guayule is not yet a crop and its commercialization will depend on the development of high rubber‐yielding cultivars. The objectives of this study were to determine if
