Abstract: A polysaccharide preparation was obtained from white tea by using hot water extraction, condensation, alcohol-sedimentation, dialysis and protein isolation. The results showed that the product is a white tea oligosaccharide with a molecular weight of 1453~1468. The white tea oligosaccharide is consist of 1 rhamnose, 2 arabinose, 1 unknown monosaccharide, 1 Glucose and 3 Galactose. There is no amino acid or other acid group in the structure of white tea oligosaccharide.

Key words: white tea, tea polysaccharide, monosaccharide, extraction, structure
