3-O-trans-caffeoyloleanolic acid (COA) is a pentacyclic triterpenoid compound, with significant anti-inflammatory effects. In this study, we report the protective effects of COA on lipopolysaccharide (LPS)-induced acute lung injury (ALI) and explored its mechanism of action. LPS was used to construct in vivo mouse ALI models to observe the effects of COA pretreatment on lung pathology, inflammation, and oxidative stress. In vitro, mouse alveolar macrophages MH-S cells were cultured and stimulated with LPS to investigate the effec
