| Abstract: | High value has been found for the bioactive polysaccharides. Plant polysaccharides have widely and promising foreground in the field of health-care foodstuff and medication because of its low toxicity and its particular functions. The extraction and purification technology is the key issue in preparation. At present,the commonly used extraction technology includes usual-water, ultrasound, microwave, supercritical fluid extraction. The purification technology includes chromatography and membrane separation. The methods and the application of new technologies in extracting and purifying polysaccharides are reviewed. Moreover the prospect of polysaccharides preparation is discussed. |
