![Figure 2:Example of mass spectrometry analysis of the main compound in one of the traditional medicine products: (A) GC–MS chromatogram, with time on the x-axis and signal intensity on the y-axis. The peak centered at 23.40 min indicates that a compound elutes from the GC column at 23.40 min. (B) Top: Spectrum of the compound eluting at 23.40 min, with each vertical bar representing an ion fragment; bottom: comparison with the reference spectrum of the molecule proposed by the library (mefenamic acid). (C) LC–HRMS chromatogram. The peak centered at 13.413 min indicates that a compound elutes from the LC column at 13.413 min. (D) Top: The HRMS MS1 spectrum of the compound eluting at RT 13.413 min, providing the exact neutral molecular mass [M + H]+ of the compound; bottom: the HRMS MS2 spectrum of the compound eluting at RT 13.413 min, enabling structural identification and comparison with a collection of reference MS2 spectra associated with identified molecules (here mefenamic acid). (E) Composition of all compound identified in high-resolution mass spectrometry. GC–MS: gas chromatography–mass spectrometry; LC–HRMS: liquid chromatography–high-resolution mass spectrometry; RT: retention time.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:33h4q6nw674jdcwfxaq2m2nl/bafkreic6enab4v5urabeohxkkpazrxyg3muz5kokc7246zii45b3easvdi)
