Process for extracting latex, resin and rubber from guayule plants, comprising, in sequence, the steps of: a. harvesting the guayule plants; b. defoliating said plants; c. either before of after said defoliating step "b", preserving the guayule plants or the defoliated plants in an environment under controlled temperature and relative humidity, for a time of between 7 and 21 days, such that the residual moisture present in the plant is maintained in the range of 30-45%; d. immersing the defoliated plants in a basic aqueous solution which comprises a stabilising system; e. grinding said defoliated plants, either before or after being immersed in said basic aqueous solution in step "d", to obtain an aqueous suspension of plant material comprising plant fragments; f. subjecting the aqueous suspension obtained in step "e" to filtration/pressing to separate a first miscella comprising said latex from a first bagasse; g. recovering the concentrated latex from said first miscella; h. dispersing said first bagasse in a polar solvent system, comprising at least one polar organic solvent and a stabilising system, to obtain a suspension; i. subjecting the suspension obtained in step "h" to filtration/pressing to separate a second miscella comprising said resin from a second bagasse; j. removing the at least one polar organic solvent from said second miscella to obtain the concentrated resin; k. removing the at least one polar organic solvent from the second bagasse obtained in step "i"; l. dispersing said desolventised second bagasse obtained in step "k" in a nonpolar solvent system, comprising at least one nonpolar organic solvent and a stabilising system, to obtain a suspension; m. subjecting the suspension obtained in step "I" to filtration/pressing to separate a third miscella comprising said rubber from a third bagasse; n. removing the at least one nonpolar organic solvent from the third miscella to obtain the rubber in the solid state; o. removing the at least one nonpolar organic solvent from the third bagasse obtained in step "m". a. harvesting the guayule plants; b. defoliating said plants; c. either before of after said defoliating step "b", preserving the guayule plants or the defoliated plants in an environment under controlled temperature and relative humidity, for a time of between 7 and 21 days, such that the residual moisture present in the plant is maintained in the range of 30-45%; d. immersing the defoliated plants in a basic aqueous solution which comprises a stabilising system; e. grinding said defoliated plants, either before or after being immersed in said basic aqueous solution in step "d", to obtain an aqueous suspension of plant material comprising plant fragments; f. subjecting the aqueous suspension obtained in step "e" to filtration/pressing to separate a first miscella comprising said latex from a first bagasse; g. recovering the concentrated latex from said first miscella; h. dispersing said first bagasse in a polar solvent system, comprising at least one polar organic solvent and a stabilising system, to obtain a suspension; i. subjecting the suspension obtained in step "h" to filtration/pressing to separate a second miscella comprising said resin from a second bagasse; j. removing the at least one polar organic solvent from said second miscella to obtain the concentrated resin; k. removing the at least one polar organic solvent from the second bagasse obtained in step "i"; l. dispersing said desolventised second bagasse obtained in step "k" in a nonpolar solvent system, comprising at least one nonpolar organic solvent and a stabilising system, to obtain a suspension; m. subjecting the suspension obtained in step "I" to filtration/pressing to separate a third miscella comprising said rubber from a third bagasse; n. removing the at least one nonpolar organic solvent from the third miscella to obtain the rubber in the solid state; o. removing the at least one nonpolar organic solvent from the third bagasse obtained in step "m".
