摘要
A process for extracting resin and rubber from guayule plants utilizing a portion of recycled miscella and a fresh solvent system. An expression step is applied to the plants to enhance recovery of resin and rubber extract. The solvent system is preferably an organic polar solvent and a hydrocarbon solvent for rubber for simultaneous resin and rubber extraction containing at least 50% by weight of the hydrocarbon solvent. The process can be a one-step method wherein resin and rubber are generally simultaneously extracted.
