Abstract: Amphiphilic hydroxypropyl-decyl chitosan was prepared by modification of chitosan.The drug-loading network gel of polyethylene oxide/sodium alginate/hydroxypropyl-decyl chitosan (PEO/SA/HP-DCCS) were prepared via chemical cross-linking method.The structure of the gel was characterized by FT-IR,XRD and SEM.Results show that this gel has good network structure and swelling property toghether with sensitiveness to pH and temperature.The gel has sustained-release effect on panax notoginseng saponins at different pH values.

Key words: hydroxypropyl-decyl chitosan, sodium alginate, polyethylene oxide, gel, panax notoginseng saponins
