摘要:

采用水浸提法提取、膜分离技术分离得到大枣粗低聚糖,再用Sephadex-G15 柱层析进行分离纯化,得到大枣低聚糖,用气相色谱- 质谱联用法测定大枣低聚糖的单糖组成为阿拉伯糖、鼠李糖、核糖、甘露糖、半乳糖和葡萄糖。同时测定了大枣中单糖的组成成分为果糖和葡萄糖。

关键词: 大枣, 低聚糖, 气相色谱- 质谱联用, 单糖组成

Abstract:

Oligosaccharides were produced from fruits of Chinese jujube by extraction using water and membrane separation followed by purification by Sephadex-G15 column chromatography and were analyzed for their monosaccharide composition by GC-MS and monosaccharides obtained in the Sephadex-G15 column purification were also analyzed by GC-MS. The oligosaccharides were composed of arabinose, rhamnose, ribose, mannose, galactose and glucose. The monosaccharides from fruits of Chinese jujube were found to be mainly glucose and fructose.

Key words: Chinese jujube, oligosaccharide, GC-MS, monosaccharide composition
