天然药物——多糖的主要生物活性及分离纯化方法

多糖具有复杂的多方面的生物活性和功能。本文综述了多糖的抗肿瘤、抗病毒、抗炎等方面的主要生物活性。多糖是大分子物质,且不同于蛋白质等大分子,它的分离纯化方法与手段有其特殊性,而通过分离纯化获得的均一的多糖组分又是进行结构分析、药理和构效关系等研究的首要条件。本文根据文献报道并结合本实验室的工作经验对多糖的各种分离纯化方法进行了介绍。

Bioactivities, Isolation and Purification Methods of Polysaccharide

Polysaccharides play multiple roles and have extensive bioactivities in life process. This review describes their major functions involved in anti-tumor, anti-virus, and anti-inflammatory bioactivities. Due to their enormous structural heterogeneity, the approaches for isolation and purification of polysaccharides are distinct from that of the other macromolecules such as proteins, etc. Yet, to achieve the homogeneity is the initial step for studies of polysaccharide structure, pharmacology, and its structure-activity relationships. According to the experiences accumulated by our lab and the recent published literatures, this review also introduces the most of methods used for isolation and purification of polysaccharides.
