Pyrrolizidine alkaloids are known to be hepatotoxic and hepatocarcenogenic compounds
that are found in common weeds that grow throughout Europe. Contamination of plants,
such as Senecio jacobaea (ragwort), that contain these secondary metabolites is common in botanicals used
as dietary supplements and may pose a health risk. In this work we show the LC/MS/MS
determination of 25 pyrrolizidine alkaloids in both plants and dietary supplements.
The accurate mass MS/MS of these compounds is presented and described. This characterization
can be the basis of routine monitoring methods and determination of other toxic pyrrolizidine
alkaloids in botanicals and dietary supplements.
