植物多糖的研究进展

多糖是由单糖连接而成的多聚物，具有促进免疫调节、抑制肿瘤及降低血糖等广泛的药理作用，具有广阔的前景；此外，由于多糖本身在质量标准、表征鉴定等方面有自身研究难度和特殊性，有待于深入研究。对植物多糖的提取、分离、鉴定、结构分析及生物活性研究发展予以综述。

Advances in studies on plant polysaccharides

Polysaccharides are combined by the monosaccharide. The investigation shows that the polysaccharides have the extensive function on immunity regulate, restraining tumor, and lowing the blood sugar. Therefore, their application has wide prospect.In addition, because there are many difficulties and distinctions of polysaccharides on the quality standards, structural characterization and so on, they need for further research.This article summarizes research developments on their extraction, separation, identification, structural analysis and biological activities.
