中文摘要:

      多糖是在自然界中广泛分布的糖类大分子物质, 具有多种生理功能和生物活性, 是维持生命活动四大基本物质之一。多糖不仅在食品开发领域备受关注, 在医药保健领域也具有广阔发展空间, 因而受到越来越多的研究者青睐。然而, 多糖的提取纯化困难, 对其生物活性作用机制也缺乏深入的了解, 限制了多糖的应用范围。本文概括了近年来多糖的提取纯化研究并分析了各方法优缺点, 同时总结了多糖生理活性研究及作用机制, 分析了目前存在的问题, 对多糖未来发展趋势进行展望, 以期为深入研究其作用机制并为开发食品、保健品或药品提供参考, 逐步构建并完善生产体系, 促进多糖产品工艺和功能应用的发展。

英文摘要:

      Polysaccharides are carbohydrate macromolecular substances distribute in the nature widely, with varieties of physiological functions and biological activities, which are one of 4 basic substances for maintaining life activities. Polysaccharides have not only attracted much attention in the realm of food development, but also owned broad space for the development of medicine and health care, which have drawn researchers’ close attention. However, the extraction and purification of polysaccharides are difficult, and the in-depth understanding of their biological activity mechanism is also lacking, which limits the application scope of polysaccharides. This article summarized the research on the extraction and purification of polysaccharides in recent years, also analyzed the advantages and disadvantages of each method, simultaneously, summarized the physiological activity research and mechanism of polysaccharides, then analyzed the cases in current, and prospected the development trend of polysaccharides for the future. It is expected to provide important reference for the in-depth study of its mechanism and the development of food, health products or drugs, gradually build and improve the production system, and promote the development of polysaccharide product technology and functional application.
