摘要: 研究普鲁兰多糖羟基与邻苯二甲酸酐反应,使普鲁兰多糖分子基团收缩,应用透析法使普鲁兰多糖纳米化。试验结果表明:通过1H-NMR技术可判断糖基的构型、氢所在的化学位置,即普鲁兰多糖羟基与邻苯二甲酸酐已结合;结合后电镜扫描图可知其颗粒形态为圆形;1∶3、1∶6、1∶9、1∶12的纳米粒子大小的平均值分别为119.2、146.5、176.4和114.3 nm。

Abstract: :The purpose of this experiment was to study the reaction of pullulan polysaccharide hydroxyl with phthalic anhydride, and to shrink the molecular group of pullulan polysaccharide by dialysis. The results showed that the configuration of the sugar group and the chemical position of the hydrogen could be determined by 1H-NMR; That is, the pullulan polysaccharide hydroxyl group had been combined with phthalic anhydride. According to the SEM, the particle shape was round. The mean particle sizes of 1∶3, 1∶6, 1∶9, 1∶12 were 119.2 nm, 146.5 nm, 176.4 nm and 114.3 nm, respectively.

Key words: pullulan polysaccharide, nanoparticles, water dialysis, sweep electron microscope(SEM), nuclear magnetic resonance(NMR)
