The Development of Biological Activity and Study on Extraction and Purification for Taxus Polysaccharides

OBJECTIVE To review the development of study on biological activity, extraction and purification for Taxus polysaccharides. METHODS To summarize the biological activity and the technique of extraction and purification of Taxus polysaccharides by reviewing the domestic and foreign articles in the past ten years. RESULTS There are multiple functions for Taxus polysaccharides such as adjusting immunity, anti tumor, alleviating ischemia reperfusion injury on myocardium, and so on. A certain development has been approached on the technique of extraction and purification for Taxus polysaccharides. The extraction methods of tissue crush and ultrasonic wave are recommended. And purification ways of peucine and hydrogen peroxide are selectable. CONCLUSION There are broad prospects on the study and exploitation of Taxus polysaccharides. The techniques of extraction, separation and purification, however, are worth further research.
