Abstract: Polysaccharide is a kind of biopolymer, which widely existing in nature, and possessing extensive pharmacological activities. However, not all original polysaccharides from natural products have ideal bioactivity, which depends on their structures. Chemical modification of polysaccharides will be benefit to improve their bioactivity and helpful to study their structure-activity relationship. Whether derivatives were prepared successfully or not, could be proven by Fourier transform infrared (FT-IR) spectra and Nuclear magnetic resonance (NMR spectra). Methods of chemical modification of polysaccharide and their structural characterizations by FT-IR and Nuclear magnetic resonance NMR spectroscopy were mainly summarized in this paper in order to provide some references,promote the development of polysaccharide biology.

Key words: polysaccharides, chemical modification, structural characterization, nuclear magnetic resonance
