摘要
以水为溶剂从小麦麸皮中制备水溶性戊聚糖,采用乙醇分级沉淀、离子交换色谱以及凝胶过滤色谱对所得到的水溶性戊聚糖进行纯化分级,得到两个组成不同的组分P WSPI1 S和P WSPII1 S.单糖组成分析表明:P WSPI1 S组分由阿拉伯糖和木糖组成,P WSPII1 S由阿拉伯糖、半乳糖组成,并含有较多的蛋白质,是一种糖蛋白复合物组分.
Water soluble pentosan was prepared from wheat bran using water. The prepared pentosan was a mixture, it was fractioned by stepwise ethanol precipitation, ion exchange chromatograph and gel filtration chromatograph, respectively. Two main purified fractions, (P-WSPI1-S) and P-WSPII1-S were obtained. P-WSPI1-S was composed by arabinose and xylose, and P-WSPII1-S was composed by arabinose and galctose. In addition. P-WSPII1-S also contained protein, which perhaps was a glucoprotein compound.
