In the present work, using quadrupole ion trap (QIT)-MS instrument, we report and discuss the gas chromatography/electron ionization mass spectrometry (GC/EIMS) (low resolution) and collision-induced dissociation tandem mass spectrometry (CID-MS/MS) fragmentation of sauroxine (MS in time) a Likopodium alkaloids isolated from Huperzia saururus (Lam.) Trevi. The mass spectrometry studies presented in this rationale has been very useful to support the structural determination of sauroxine and Likopodium alkaloids analoges.
