| 摘 要： | 多糖是荔枝壳的重要活性成分，本研究采用阴离子交换柱和凝胶过滤柱对荔枝壳多糖进行分离纯化。凝胶渗透色谱测定其分子量为14000 Dal。通过气相色谱测定其单糖组成为甘露糖、半乳糖和少量的阿拉伯糖，分子链由1，2键、1，3键和1，6键组成，不含1，4键。红外光谱分析表明甘露糖以β-D-甘露糖形式存在，不含羧基基团。

| Abstract: | Polysaccharide was an important functional composition in litchi pericarp.Anion exchange column and gel filtration column were used to isolate and purify the major polysaccharide extracted from litchi pericarp.The profile of gel permeation chromatography (GPC) showed its molecular weight as 14000 Dal.Monose composition of the major polysaccharide was determined by using gas chromatography (GC).It mainly comprised mannose and galactose,and arabinose.Its structure was further identified by using infrared (IR) spectra. |
