摘　　要：双水相萃取技术是一种易于放大、操作条件温和、可连续化操作的新型分离技术。本文综述了新近发展的不同的双水相体系(聚合物-盐-水、有机溶剂-盐-水、离子液体-盐-水、离子液体-表面活性剂-盐-水)的性质,及萃取(提取)蛋白质、氨基酸、抗生素和中药材中小分子有效成分等的影响因素;总结了双水相萃取与其它技术的联用,展望了双水相体系的应用前景。Extraction with aqueous two- phase system （ATPS） is a novel separation technique, which shows some advantages including easy scale-up, mild conditions and continuous operation.The properties and applications of newly developed different ATPSs（ polymer-salt- water, organic solvent- salt- water, ionic liquid- salt- water, ionic liquid- surfactant- salt - water） in extraction of proteins, amino acids, antibiotics and other small molecules in herbs were reviewed. ATPS extraction combining with other technologies were summarized, and the prospect of ATPSs was also discussed.
