Abstract:
Objective: To study the chemical structure of polysaccharide CDP 4 isolated from Cistanche deserticola Y.C.Ma. Methods: The chemical properties of CDP 4 were determined by using chemical method and spectrocospic method. Results: CDP 4 was composed of glucosyl group, with the ratio 1,4 linkage glc p ∶1,6 linkage glc p =3∶1,and its mean molecular weight 1.4 ?10 4. By means of methlylation analysis, complete acid hydrolysis analysis, NMR spectrum, the linkages and sequence information of CDP 4 were obtained. Conclusion: CDP 4 is a new linear glucan.
