| Abstract: | To study the physical and chemical properties and quality of polysaccharides in Rabdosia rubescens.Crude polysaccharides of Rabdosia rubescens were obtained by extraction in hot water and dilute alkali successively,precipitation with ethanol and removal of protein by method of isoelectric point.STPS-Ⅰ,STPS-Ⅱ,JTPS-Ⅰ,JTPS-Ⅱ were isolated by a combination of ion exchange chromatography on Q Sepharose 4 Fast Flow and gel permeation over Sephacryl S-100 and with high purity.Their chemical characteristics including the content of total sugar,uronic acid,sulfate and protein as well as monosaccharide composition and molecular weight were investigated.The results showed that the molecular weight of different components of polysaccharides in Rabdosia rubescens was similar,while chemical composition and monosaccharide composition obvious different. |
