Objective To investigate and analyze anticomplement and antitussive activities and the active ingredients of the extract of Chimonanthus nitens leaf. Methods The classical anti-complement pathway and the concentrated ammonia-induced cough model was used to compare the activity of the different polar parts of C. nitens leaf, and the polar parts with anti-complement and antitussive activity were determined. A preliminary analysis of the chemical composition in activity extract was identified by high performance liquid chromatography-mass spectrometry. The main chemical components in the C. nitens leaf of antitussive and antibody activity were also evaluated. Results The ethyl acetate extract of C. nitens leaf had both anti-complement and antitussive effects. A total of 28 compounds were initially identified through mass spectrometry analysis. Kaempferol-3-O-rutinoside and kaempferol had both antitussive and anti-complement activities. Conclusion The ethyl acetate extract of C. nitens leaf has good anti-complement and antitussive activities, and the mainly active ingredients in it were kaempferol-3-O-rutinoside and kaempferol that could be used as quality-controlling chemical markers.
