Structure characterizations of polysaccharide CBP3 from Clanis bilineata tsingtauica Mell

The structure characterizations of Clanis bilineata tsingtauica Mell polysaccharide were investigated.The studies showed that CBP3 was composed of seminose,glucose and galactose in a molar ratio of 27.89∶ 1∶ 3.16.The results showed that CBP3 may be a kind acidic polysaccharide containing carboxyl with- o- glycosidic linkages and β- glucopyranose between sugers and amino acids by means of several analysis methods,such as infrared scanning,H- NMR,β- elimination reaction,KI- I₂ reaction,x- ray powder diffraction and scanning electron microscopy analysis,which had long side chains and more branches.CBP3 were amorphous materials with crystals partly.
