By employing a combined approach to evaluate both mucosa-mediated and microbiota-mediated metabolism, we identified 37 parent compounds (predominantly flavonoids) and 48 metabolites. The ileum and colon were confirmed as primary metabolic sites, predominantly involving Phase I and Phase II reactions. Metabolic pathways were detailed using quercetin as a representative phytoestrogen. Furthermore, we analyzed the intestinal metabolic patterns of nine in vivo direct-acting compounds highly correlated with CS's estrogenic effects.

Investigating the impact of CXND on allergic rhinitis and further defining its potential active ingredients and mechanism of action were the objectives of this study. The effective components of CXND were determined by ultra-performance liquid chromatography, and the core genes and important pathways of CXND in the treatment of AR were analyzed by network pharmacology.

The guinea pig model was induced by OVA to study the effects of CXND on the STAT3/IL-17A/NF-κB signaling pathway and related inflammatory factors.
