Multi-Omics Reveals Active Components and Mechanisms of Heat-Processed Gypenosides Hepatoprotective Against APAP Injury.

ABSTRACT: This study elucidates the hepatoprotective mechanisms of heat-processed Gynostemma pentaphyllum (Thunb.) Makino saponins (HGyp) against APAP-induced liver injury using serum pharmacochemistry, metabolomics, and network pharmacology. HGyp significantly mitigated liver damage in mice, as confirmed by biochemical and histopathological analyses. UPLC-MS identified 38 bioactive compounds, including 16 prototype saponins and 11 metabolites. Network pharmacology and molecular docking revealed damulin A/B, gypenosides (L/LI/LVI/XLVI), and ginsenosides (Rg3/Rd) as key components targeting GRB2, FGF2, MMP2, STAT3, CASP3, and HSP90A. Western blotting confirmed the HGyp-mediated downregulation of hepatic HSP90A and STAT3. Metabolomics identified four critical pathways, PPAR, ferroptosis, and th
