Wildi, E., Langer, T., Schaffner, W. and Biiter, K. B. 1998. Quantitative analysis of petasin and pyrrolizidine alkaloids in leaves and rhizomes of in situ grown Petasites hybridus plants. Planta Medica, 64 264-267. [Pg.241]

Gas chromatography coupled to mass spectrometry is a widely used analytical method [31] but does require prior reduction of the involatile N-oxides. Additionally, there are problems associated with some alkaloids that require prederivatization to enhance the GC characteristics. These requirements for prederivatization can adversely affect the GG-MS interpretation, especially at trace levels of alkaloids [32]. Gombined SPE-LC-MS approaches have provided methods for qualitative profiling and quantitative analysis of pyrrolizidine alkaloids and their N-oxides. [Pg.383]
