| 摘 要： | 白茶经热水浸提、浓缩、醇沉、透析等工序制得一种白茶多糖,这种多糖采用saveg法处理前后的IR谱图和单糖组成均无变化。结果表明,白茶多糖是一种由8个单糖组成的寡糖,分子量为1453～1468,其结构中含有1个鼠李糖基、2个阿拉伯糖基、1个未知单糖A基、1个葡萄糖基和3个半乳糖基,单糖通过苷键结合。白茶多糖结构中不含氨基酸或其他酸性基团。

| 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. |
