Abstract: The 50βK membrane has been ascertained as the best membrane for separation and concentration of tea polysaccharides, and on the basis of the result, the treatment had been optimized, and the result showed that contents of total sugar reached 30.37%, and those of tea polysaccharides arrived at 16.89%. In compared with the control, the scavenging rate of ·OH were increased by 39.89%. The experiment showed that tea polysaccharides is separated and concentrated by membrane, and the activity of tea polysaccharides could be remained.

Key words: Key wards: tea polysaccharides, membrane, separation and concentration, ·OH;
