The invention discloses a wolfberry-
astragalus compound
polysaccharide with an anti-myelosuppression effect as well as a preparation method and application of the wolfberry-
astragalus compound
polysaccharide. The wolfberry-
astragalus compound
polysaccharide is prepared by adopting a process of separately extracting wolfberry polysaccharide and
astragalus polysaccharide and then mixing, the total
sugar content is 70-80%, the
uronic acid content is 10-14%, and the wolfberry-astragalus compound polysaccharide has specific molecular
weight distribution and
monosaccharide composition characteristics. Animal experiment results show that the wolfberry and astragalus compound polysaccharide can significantly improve
peripheral hemopenia of myelosuppression mice induced by
cyclophosphamide, promote
recovery of the number of leukocytes, lymphocytes, monocytes and neutrophils, and effectively reverse
weight loss caused by
chemotherapeutic drugs. The wolfberry-astragalus compound polysaccharide provided by the invention is high in safety and remarkable in anti-myelosuppression effect, and can be used for preparing medicines or functional preparations for improving myelosuppression related diseases.
