Abstract: Objective :To compare the effect between the membrane separation technique and the traditional method being used to concentrate polysaccharides from Liuwei Dihuang formula. Methods : The extract liquid of Liuwei Dihuang formula was divided into several levels and segments using nanofiltration and ultrafiltration of 10 000Mr.The polysaccharides in every level's extracted liquid were quantitate by sulfuric acid-anthrone colorimetric method at detecting wavelength 625 nm. Results : The polysaccharides in the production made by membrane separation technique were 6.5 times as much as that in the production made by the traditional method. Conclusion : The membrane separation technique was superior in concentration polysaccharides compared with the traditional method.
