The raw tea polysaccharides (RLTPS) and the aged tea polysaccharides (ALTPS) from raw and aged Liupao tea were extracted and purified to afford five refined fractions. Component analysis revealed that the crude polysaccharide content from raw Liupao tea increased from 1.83 ± 0.09 g / 100 g to 3.44 ± 0.28 g / 100 g and the molecular weight decreased after fermentation. Structural analysis indicated that the molar ratio of rhamnose, galactose, and galacturonic acid increased in refined ALTPS. All the refined polysaccharides were glycoprotein complexes
