Ephedra sinica Stapf polysaccharide is a pure acidic uniform polysaccharide extracted from the traditional Chinese medicine Ephedra sinica Stapf. In our past research, it was found that it has anti-inflammatory response and suppresses immunity. Therefore, in this experiment, mice were infected with FM1 virus, treated with Ephedra sinica Stapf polysaccharide, and metagene sequencing was used to sequence the mouse intestinal contents. As a result, we found that Ephedra sinica Stapf polysaccharide has obvious therapeutic effect on acute lung injury caused by H1N1. In the intestinal flora, the abundance of Lactobacillales and Bifidobacteriaceae increased significantly, and the metabolome increased significantly in the KEGG pathway. The intestinal flora may be an important target of Ephedra sinica Stapf polysaccharides metabolism against H1N1.
