摘要: 植物多糖是一种从植物中提取获得的高分子化合物,其结构复杂,具有多种生物活性,多糖通过调节肠道菌群对宿主产生有益作用是近年来研究的热点。研究表明,肠道菌群将非淀粉多糖代谢生成短链脂肪酸,发挥调节宿主代谢、免疫系统和细胞增殖等多种生理功能,改善肠道环境,促进人体健康。植物多糖化学结构与物理性质是肠道菌群利用差异的基础,决定了其益生作用强弱。不同提取、分离纯化以及修饰方法均可改变植物多糖结构,从而影响其活性。本文系统论述植物多糖与其益生作用的关系以及影响植物多糖结构的因素,旨在为植物多糖的精准化开发利用提供参考。

Abstract: Plant polysaccharides are polymers derived from plants with complex structures and various biological activities. Polysaccharides have a beneficial effect on hosts by regulating their intestinal flora, which has become a hot research topic in recent years. Studies have shown that the intestinal flora can metabolize non-starch polysaccharides into short-chain fatty acids, exerting a variety of physiological functions such as regulating host metabolism, immune system and cell proliferation, improving the intestinal environment, and ultimately promoting human health. The chemical structure and physical properties of plant polysaccharides are the basis for their differential utilization by the intestinal flora and determine the strength of their prebiotic effects. The structure of plant polysaccharides varies depending on the extraction, purification and modification methods used, affecting their activity. This paper systematically discusses the prebiotic effects of plant polysaccharides and the factors that affect their structure, which will provide a reference for the precise development and utilization of plant polysaccharides.

Key words: plant polysaccharides; intestinal flora; structure-activity relationship; prebiotics
