Abstract

Positions of substitution with sulphate in three water-soluble sulphated derivatives of chitosan were analysed by 13C n.m.r. The structures of N-acetylchitosan 3,6-O-disulphate, sodium chitosan N-, 6-O-disulphate, and sodium chitosan 6-O-monosulphate were confirmed.

摘要

通过碳-13核磁共振分析了壳聚糖的三种水溶性硫酸化衍生物中硫酸根取代的位置。证实了N-乙酰壳聚糖3,6-O-二硫酸酯、壳聚糖N-，6-O-二硫酸酯钠和壳聚糖6-O-单硫酸酯钠的结构。
