Abstract
A method for extracting polyisoprenes from cells, comprising the steps of contacting the cells with an organic protein-denaturing compound, rupturing the cells to release the polyisoprene from the cells and recovering the polyisoprene. The preferred protein denaturing compound comprises an aqueous solution of a guanidine salt.

A method for extracting polyisoprenes from cells containing proteins and polyisoprenes, comprising the steps of:
- contacting the cells with an organic protein-denaturing compound comprising an aqueous solution of a guanidine salt;
- rupturing the cells to release the polyisoprene from the cells and;
- recovering the polyisoprene.
An improved process comprising the steps of treating polyisoprene-containing plant cells with a solvent to extract the polyisoprene and then separating the polyisoprene from the solvent, wherein the improvement comprises;
- using a compound comprising an aqueous solution of a guanidine salt.
An improved process comprising the steps of treating polyisoprene-containing plant cells with a solvent to extract the polyisoprene and then separating the polyisoprene from the solvent, wherein the improvement comprises;
