METHOD FOR THE SEPARATION OF THE ISOPRENIC CONSTITUENTS OF GUAYULE

Method for the separation of at least one isoprenic constituent from the resin of a plant of guayule and/or of the guayule type comprising the steps of: a) providing a defatted resin of guayule and/or of the guayule type; b) subjecting the defatted resin to partitioning of the liquid-liquid type with solvents that are immiscible in each other thus obtaining an apolar extract containing the isoprenic constituents guayulin A, guayulin B and argentatin B; and a polar extract containing the isoprene constituents argentatin A, argentatin C and argentatin D; and c) separating at least one isoprenic constituent from said polar extract and/or from the apolar extract thus obtained, wherein step c) comprises a step in which the polar extract is subjected to partitioning of the liquid-liquid type with solvents immiscible in each other and/or a step in which the apolar extract is subjected to partitioning of the solid-liquid type.
