“…Then the acetone extract was filtered using a Buchner funnel (1 mm mesh), and the roots on the funnel were washed with copious amounts of acetone. The air-dried, deresinated roots were then extracted with 300 mL of chloroform (ACS grade, Sigma Aldrich, Germany) or other nonpolar solvents (ACS grade, Sigma Aldrich, Germany) , for 24 h at room temperature with periodic shaking. Solubilized rubber was decanted slowly into a preweighed flask without disturbing precipitated plant tissue.…”

“…Solid rubber extraction with organic solvents can be accomplished via simultaneous and sequential solvent extraction. A polar solvent (acetone) is used first for the removal of extractives, and a nonpolar solvent (cyclohexane or hexane) is used for the extraction of rubber , . Solvent processes were demonstrated at a pilot scale with guayule .…”

“…Before the breeding procedure, the resin content used to be about 40% of the rubber content, while after such a process, it increased up to 150% [14]. Sesqui-and tri-terpenes account for 37% and 52% of the resin produced by resin vessels [12] with the sesquiterpene, guayulin A, alone, accumulating to 1%-13.7% [15][16][17] depending on the variety and harvest date. Three other guayulins (B, C and D) occur in smaller amounts.…”

“…The resinous material from guayule is composed of readily recognizable fatty acid triglycerides and complex mixtures of terpene and sequiterpenoid compounds [13]. The compounds identified include organic acids (cinnamic, p-anisic, palmitic, stearic, oleic, linoleic, and linolenic acid), sesquiterpene esters (guayulin A, B, C, and D), triterpenoid esters (argentatin A-H) [18] and polyphenols (tannins and flavonoids) [16].…”

“…* Texas Engineering Extension Service. Schloman (1986) has reported that guayulin A (la) is present at the level of 3600 ppm in the whole shrub and is seasonally variable and dependent on extraction conditions (Schloman et al, 1988). The Gila Indians established stands of the shrub in the early 1980s (Milthorpe and Patterson-Jones, 1991), and the Firestone Tire and Rubber Co. processed the harvest into gum at their facilities in Arizona in the years [1987][1988][1989][1990] (Wagner and Schloman, 1991).…”
