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 glcp:1,6-linkage glcp=3:1,and its mean molecular weight 1.4 x 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.
