摘要: 一些多糖具有提高免疫力、抗肿瘤等功能活性,但因其含有大量羟基,易形成分子内和分子间氢键,难 溶于水,严重制约了其应用;因此有必要对其进行修饰改性。离子液体作为一种新型绿色溶剂,对多种有机、无 机大分子物质有着较好的溶解能力,可作为介质对多糖进行物理改性和化学改性。本文综述了多糖在不同离子液 体中的溶解性及机理,以及以离子液体为介质的修饰改性对多糖结构和理化性质的影响,并对目前研究中存在的 问题进行总结,对未来的研究趋势进行展望,旨在为改善多糖理化性质、拓宽其应用领域提供理论依据。

Abstract: Some polysaccharides have immune-enhancing, anti-tumor and other pharmacological effects, but contain a large number of hydroxyl groups that easily form intramolecular and intermolecular hydrogen bonds, thereby making them difficult to dissolve in water, and consequently restricting their application. Thefore, it is necessary to modify those polysaccharides. As a new type of green solvent, ionic liquid has a good ability to dissolve a variety of organic and inorganic macromolecules, and can be used as a medium for physical and chemical modification of polysaccharides. In this paper, the solubility and underlying mechanism of polysaccharides in different ionic liquids are reviewed. The effects of modification with ionic liquid on the structure and physicochemical properties of polysaccharides are discussed. Problems currently existing in this field of research are pointed out and future trends are dicussed. The aim of this paper is to provide a theoretical basis for improving the physicochemical properties of polysaccharides and broadening their scope of application.

Key words: polysaccharides, ionic liquids, modification, physicochemical properties
