水溶性壳聚糖有序聚集体作VC药物载体的研究
Ordered Assemblies of Water-Soluble Chitosan as Carriers for Vitamin C
摘要
Abstract
Two ordered assemblies of water-soluble chitosan were formed in aqueous solution at various chitosan concentrations and temperatures. Steady and dynamic rheological properties of both assemblies were investigated at different temperatures. Meanwhile, the effect of both assemblies as separate carriers for vitamin C on sustained release and stability of vitamin C was determined. The steady rheological curves indicated that both assemblies had strong pseudoplastic property. The dynamic rheological curves revealed that the assembly I could be fitted with Maxwell model under the condition of low frequency and performed as an elastomer under the condition of high frequency. In the tested frequency range, the loss modulus（G ″） of the assembly II was always lower than its storage modulus（G ′ ） . Therefore, both assemblies allows sustained release and stability maintenance of vitamin C.关键词
