Abstract: NMR (1H NMR, 13C NMR, 1H-1H COSY, HSQC and HMBC) and mass spectra of a fluorine derivative of tetrahydroberberine were reported and interpreted. The NMR signals were assigned and the substituted positions for the fluorine atom was identified. The structure of the compound was determined with the spectral data. The probably fragmentation pathways of the compound were also discussed.

Key words: nuclear magnetic resonance, structure elucidation, mass spectrometry, fluoro tetrahydroberberine
