Experiences with the quantitative trace analysis of pyrrolizidine alkaloids using GCMS and LCMS

, : Experiences with the quantitative trace analysis of pyrrolizidine alkaloids using GCMS and LCMS. Poisonous plants and related toxins: 453-458

This report describes the advantages and disadvantages associated with the application of gas chromatography/mass spectrometry and liquid chromatography/electrospray and atmospheric pressure chemical ionization mass spectrometry to trace analysis of pyrrolizidine alkaloids and PA N-oxides.
