摘要

利用水提、醇沉、多种色谱分离方法从苦荞粉中提取纯化到一种多糖。该多糖易溶于水,分子质量为8.26×105～2.85×106。经毛细管电泳测定其由单一的半乳糖组成的均一多糖。通过核磁共振分析得出其结构为β-1→6半乳聚糖。

关键词： 苦荞; 多糖; β-半乳聚糖

Abstract

Polysaccharides was extracted with water from Tartary buckwheat and isolated by column chromatography(DEAE-cellulose,Sephacryl-400 and HW-55).Its was β-1→6 galacan.Its chemical structure was elucidated by means of 1H-NMR,13C-NMR,135DEPT spectroscopic analyses.The Polysaccharides was reported for the first time from Tartary buckwheat.

Key words： tartary buckwhea; polysaccharides; β-galacan
