Preparation and charactarisition of a new type water soluble chitosan derivative / 中国海洋药物

ABSTRACT

Reaction of chitosan with glucose, galactose and lactose was performed in lactic acid MeOH to give corresponding schiff's base derivatives, the following reduction was carried out in the presence of sodium cyanoborohydride to prepare branched chain water soluble chitosan derivatives. The structure of derivatives were Confirmed by 1 HNMR and 13 CNMR.
