Evaluating chemical indices of guayule rubber content: Guayulins A and B

Industrial Crops and Products, 2009
Abstract Guayule ( Parthenium argentatum Gray) is now a commercial crop for the production of high-quality, hypoallergenic natural rubber latex. Because guayule is relatively resistant to both insect and disease pests, its cultivation requires little chemical input.

Quantitative and Qualitative Variations in Resin Content and Guayulins (A and B) among Different Guayule Cultivars

Journal of Agricultural and Food Chemistry, 1995
Guayule has substantial quantities of resin which is often discarded after rubber extraction. Resin from 13 cultivars of guayule from India was analyzed for its qualitative and quantitative variations. Stem had 6.15% resin followed by roots (5.91%), branches (5%), leaves (3%), and flowers (3.06%). Resin percent varied significantly among the cultivars.

Concise multigram purification of guayulin A from guayule

Journal of Agricultural and Food Chemistry, 1994
An efficient medium-scale isolation of guayulin A is described. The digestion of defoliated guayule in hot acetone followed by filtration and concentration yields an extract containing resin, low molecular weight guayule rubbers (LGR), and water. Removal of the latter two components affords a transparent green oil.
