Ardisiae Crenatae Radix is an ethnic medicinal herb with good anti-inflammatory activity. Ardisiacrispin B is one of the main components in Ardisiae Crenatae Radix extract, with a content of up to 16.27%, and it may be one of the pharmacological components through which Ardisiae Crenatae Radix exerts anti-inflammatory activity. At present, reports on ardisiacrispin B mainly focus on anti-tumor effects, and there have been no reports on anti-inflammatory activities. As a triterpenoid saponin, due to its large molecular weight and complex structure, the composition of substances that function in the body may include other forms after metabolism, in addition to compounds with original structures. Exploring the anti-inflammatory effects on the prototypes and metabolites of the compound may provide a more comprehensive response to the characteristics of ardisiacrispin B's anti-inflammatory action. In this study, ardisiacrispin B was analyzed for metabolites to explore its metabolic processes in vivo. Subsequently, the anti-inflammatory effects of the prototypes and metabolites were further analyzed through network pharmacology, with the expectation of discovering the signaling metabolic pathways through which they may act. Finally, the anti-inflammatory effects of ardisiacrispin B in vitro and the effects on key signaling pathways at the protein level were explored. The results of this study showed that the isolated compounds were confirmed to be ardisiacrispin B. After the metabolite analysis, a total of 26 metabolites were analyzed, and the metabolism process in rats mainly involves oxidation, dehydration, glucuronide conjugation, and others. Speculation as to the anti-inflammatory molecular mechanisms of the prototypes and metabolites of ardisiacrispin B revealed that it may exert its anti-inflammatory effects mainly by affecting the PI3K-AKT pathway. Further anti-inflammatory mechanisms demonstrated that ardisiacrispin B had a good anti-inflammatory effect on LPS-induced RAW264.7 cells and a strong inhibitory effect on NO, TNF-α, and IL-1ß release in cells. Furthermore, it had significant inhibitory effects on the expression of PI3K, P-PI3K, AKT, and P-AKT. This study supplements the gaps in the knowledge on the in vivo metabolic process of ardisiacrispin B and explores its anti-inflammatory mechanism, providing an experimental basis for the development and utilization of pentacyclic triterpenoids.
