Renal fibrosis is caused primarily by oxidative stress and inflammation. We identified the components of Plantaginis semen and elucidated their anti‐fibrotic and anti‐inflammatory mechanisms. The renoprotective components and underlying molecular mechanisms of P. semen were investigated in rats with adenine‐induced chronic tubulointerstitial nephropathy (TIN) and in idole‐3‐acetic acid (IAA)–stimulated NRK‐52E cells. Acetate and n‐butanol extracts were found to be the bioactive fractions of P. semen. A total of 65 compounds including geniposidic acid (GPA), apigenin (APG), and acteoside (ATS) were isolated and identified. Among the seven main extract components, treatment with GPA, APG, and ATS reduced the serum levels of creatinine and urea in TIN rats. Mechanistically, GPA ameliorated renal fibrosis through repressing aryl hydrocarbon receptor (AHR) signaling and regulating redox signaling including inhibiting proinflammatory nuclear factor kappa B (NF‐ƙB) and its target gene products as well as activated antioxidative nuclear factor‐erythroid‐2‐related factor 2 (Nrf2) and its downstream target gene products in both TIN rats and IAA‐stimulated NRK‐52E cells. The inhibitory effect of GPA on AHR, NF‐Ƙb, and Nrf2 signaling were partially abolished in IAA‐stimulated NRK‐52E cells treated with CH223191 compared with untreated IAA‐stimulated NRK‐52E cells. These data demonstrated that GPA alleviates oxidative stress and inflammation partly by suppressing AHR signaling. 10.1002/ptr.8324 http://onlinelibrary.wiley.com/termsAndConditions#vor |
