Abstract: To elucidate the fermentation-induced chemical transformation mechanisms of secondary metabolites, the chemical difference between raw and fermented Ziziphi Spinosae Semen(SZR) using Poria cocos (Schw.) Wolf was revealed by integrating UPLC-Q-Orbitrap MS/MS techniques-based untargeted metabolomics. 24 chemical components were characterized in fermented Ziziphi Spinosae Semen(FSZR). The 7 differential marker compounds between SZR and FSZR were rapidly discovered by untargeted chemomics-based mining approach using OPLS-DA. Meanwhile, the relative contents of 24 chemical components were analyzed by t-Test, which was used to make metabolic pathway analysis, showing that deacetylate and deglycosylation were the major metabolic reaction under fermentation by Poria cocos. The result shows that the proposed strategy meets the technical demands for the overall chemical characterization of fermented herbal medicines, and therefore may be considered a promising approach for delving into the scientific basis in traditional fermentation of herbal medicines.
