In this study, the protective effects of Cimicifugae Rhizoma (CR) was demonstrated in Pseudomonas aeruginosa-induced pneumonia mouse model. To identify the anti-inflammatory ingredients, an ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS) integrated nuclear factor κB (NF-κB) luciferase reporter assay screening system was carried out. As a result, some caffeic acid derivatives, including caffeic acid, ferulic acid/isoferulic acid, fukinolic acid, and cimicifugic acid ingredients were identified as the potential effective compounds from CR. For testing the anti-inflammatory capacity, caffeic acid was demonstrated to inhibit NF-κB and reduce the levels of IL-6 and IL-8 in TNF-α-treated BEAS-2B cells in a dose-dependent manner. Hence, CR preparations and its cinnamic acid derivatives have the possibility to be developed as a complementary therapy in the treatment of respiratory system infection in clinics.
