Abstract:

Astragali Radix is a Chinese herbal medicine which is used for both medicine and food,Astragalus polysaccharides is the most important natural active ingredients which has functions of improving immunity and antioxidant ability and intestinal microecology,and has the capability of anti-microbial and anti-virus without drug resistance,of which immune regulation is the most prominent.Numerous studies have demonstrated that Astragalus polysaccharides have significant immunomodulatory effect in vivo and in vitro.The authors introduced the regulatory effect of Astragalus polysaccharide on immune related genes,its role in organ immunity,cellular immunity,cytokines and intracellular messenger substances,cardiovascular system immunity,antibacterial immunity and antiviral immunity,and summarized its application used as immune adjuvant in CSF,PCVD,FMD,PRRS and MPS in the latest research progress.At present,most researches are limited to the structure of Astragalus polysaccharide,which is mainly used as immune adjuvant and animal feed additive,and its application range is narrow which lacks deep research and development.In the future,we should strengthen the separation and purification of low molecular weight Astragalus polysaccharide,explore its structure characteristics and immune regulation of the structure-activity relationship to improve its curative effect,promote its clinical application.

Key words: Astragalus polysaccharides; pharmacologic action; pig; prevention and treatment of diseases
