Abstract: In this paper, coarse tea polysaccharides were preliminarily purified by means of Sevag deprotein, ethanol precipitation, two times dialysis etc. A large component, nominated TGP, was fractionated from the polysaccharides by Sephadex G100 gel column chromatography, eluted by 0.1mol/L NaCl. The average molecular weight was determined to be 6.0× 104 Dol by gel permeation chromatography.
