Use of Ultrafiltration Technology in the Purification of Polysaccharide from Liuwei Dihuang Decoction
超滤技术在六味地黄软胶囊多糖精制工艺中的应用

This study was aimed to purify polysaccharide from Liuwei Dihuang decoction by using ultrafiltration technology. In the study, ultrafiltration technology was applied with pharmacodynamics to find active extracts and confirm the best ultrafiltration parameters such as the material, configuration, permeability of the ultrafiltration membrane and the quantity of liquor. The result showed that the ultrafiltration technology has more virtues such as simple manipulation, less energy consumption, and better result than traditional methods. It will have good prospect in the industrial use.
