Abstract:

Ginsenoside Rh4, as a bioactive component obtained from Panax notoginseng, has excellent pharmacological properties. However, its role in regulating gut microbiota and intestinal inflammation is still poorly understood. Thus, the aim of this study is to investigate the effect of Rh4 on gut microbiota, especially antibiotic-induced microbiota perturbation, and the underlying mechanisms. C57BL/6 mice were given different doses of Rh4 after the establishment of a gut microbiota disturbance model with antibiotics. Our data revealed that Rh4 administration could greatly improve the pathological phenotype, gut barrier disruption, and intestinal inflammation in mice that had been antibiotic-induced. Notably, it was found that Rh4 significantly inhibited the TLR4-MyD88-MAPK signaling pathway. In addition, Rh4 treatment could significantly increase the number of short chain fatty acids (SCFAs) and bile acids (BAs). These changes were accompanied with beneficial alterations in gut microbiota diversity and composition. In conclusion, Rh4 improves intestinal inflammation and induces potentially beneficial changes in the gut microbiota, which are conducive to revealing host-microbe interactions.
