 Hosta plantaginea flower is an important Chinese herb in treating chronic pharyngitis (CP)
  however, its pharmacodynamics against CP and the underlying mechanisms remain unclear. This study demonstrated that the ethyl acetate (HPB) and n-butanol (HPC) fractions of the H. plantaginea flower were the active fractions against CP, as they significantly increased the body weight, improved damaged pharyngeal tissues, and reduced TNF-α, PGE2, IL-1β, and IL-6 levels in rats induced by 5% ammonia solution. Metabolomics studies identified 55 differential metabolites, with 26 being reversely regulated by HPB and HPC. These 26 metabolites are closely associated with phosphoinositide 3-kinase-protein kinase B (PI3K-Akt), just another kinase-signal transducers and activators of transcription (JAK-STAT), mitogen-activated protein kinases (MAPKs), and nuclear factor kappa-B (NF-κB) pathways. Mechanically, HPB and HPC prominently suppressed the expression of phosphorylated PI3K, Akt1, JAK1, STAT3, JNK, p38, Erk, p65, and inhibitor of NF-κB (IκBα) proteins. Finally, HPLC analysis identified flavonoids as the primary phytochemicals of HPB and HPC. In conclusion, HPB and HPC are the main active fractions of H. plantaginea flower against CP, acting by regulating energy metabolism and inhibiting PI3K-Akt, JAK-STAT, MAPKs, and NF-κB signaling pathways, and the flavonoids are the primary chemical constituents. Our findings provide a new perspective for the utilization of this herb.
