Abstract:
To determine the number average molecular mass of chitosan-oligosaccharide by u-sing the acetylacetone's method based on the color-producing reaction with amino terminal . Via the tests on the repetitiveness, accuracy and the stability, supposed this method was reliable. At the same time, the contrastive results of HPLC and the traditional K3Fe(CN)6 method indicate that the acetylacetone method was more suitable for the determination of chitosan-oligosaccharide molecular mass.
