Background: Steamed Panax notoginseng saponins (SPNSs) can alleviate cyclophosphamide-induced anemia. However, the hepatointestinal effects of SPNSs and their role in ameliorating cyclophosphamide-induced anemia remain unexplored. Objective: To elucidate the hepatointestinal effects of SPNSs and their role in ameliorating cyclophosphamide-induced anemia. Methods: Blood samples were collected and analyzed on days 7 and 14. Liver tissues and small intestinal villi structures were observed via HE staining. Liver and colon content metabolites were detected by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Liver proteins were analyzed by using an Orbitrap Astral mass spectrometer. Colon content microbiota composition was assessed via metagenomics. Signaling pathway protein expression was analyzed via Western blotting (WB). Results: SPNSs significantly increased the red blood cell (RBC) count and hemoglobin (HGB) level by day 14 and alleviated hepatointestinal damage. Hepatic metabolomics revealed: the most abundant metabolites were fatty acids and stachyose on day 7 and amino acid and arachidonic acid derivatives on day 14. KEGG analysis implicated cAMP signaling. Proteomics revealed upregulated immune-related proteins and enhanced PI3K pathway activity (WB-validated). Colon content metabolomics showed increased daidzein, 3-(2,5-dimethoxyphenyl) propanoic acid, γ-CEHC, and adenosine in SPNS groups on day 14. Metagenomics indicated differential abundances of Heminiphilus faecis, Phocaeicola sartorii, and s-bacterium_J10.2018 on day 14. Multiomics integration demonstrated significant correlations between hepatic metabolites, hematopoietic proteins, colon content metabolites, and probiotic bacteria. Conclusions: SPNS alleviates cyclophosphamide-induced hepato-intestinal injury in anemic mice by modulating the gut microbiota and enhancing hepato-intestinal immune defense. Additionally, SPNSs ameliorate anemia in cyclophosphamide-treated mice by activating the cAMP/PI3K/AKT pathway, promoting hepatocyte proliferation, and increasing hematopoietic protein expression.
