Beta-glucan composition and application thereof

The invention provides a beta-glucan composition and application thereof. Specifically, the invention provides an application of a beta-glucan composition in preparation of a composition for improvingor treating immune-related diseases, wherein beta-glucan is beta-glucan containing beta-1, 3 and beta-1, 6 glucoside bonds in molecules, and the molecular weight of beta-glucan is 1-50kD. The beta-glucan has the advantages of being novel in structure, controllable in quality, rich in source, simple in preparation process, high in product purity, high in biological activity, easy to produce industrially and the like, and the water-soluble beta-glucan composition obtained through the preparation method has better anti-tumor activity; The beta-glucan composition is expected to be developed intoa safe and effective new class of medicines for improving or treating immune-related diseases and resisting tumors. 本发明提供了一种β-葡聚糖组合物及其用途。具体地，本发明提供了一种β-葡聚糖组合物在制备改善或治疗免疫相关疾病的组合物中的应用，所述的β-葡聚糖是分子中含有β-1,3与β-1,6葡萄糖苷键的β-葡聚糖，其分子量为1-50
