Summary
The use of pyrolysis mass spectrometry and pyrolysis-GC/mass spectrometry is described for the identification of anthocyanins. Minimal time and sample consumption are the advantages of the method, as no derivatization is requested. In pyrolysis mass spectrometry the substituent at carbon two gives rise to a major thermal fragment that is representative for the type of anthocyanin. Glycosides and aglycones are also easily differentiated.
Zusammenfassung
Die Anwendung der genannten Verfahren wurde beschrieben. Minimaler Zeitaufwand und Probenverbrauch sind die Vorteile dieser Verfahren, da keine Derivatisierung erforderlich ist. Bei der Pyrolyse/Massenspektrometrie bildet der am C2 gebundene Substituent ein größeres thermisches Spaltprodukt, das den Typus des Anthocyans kennzeichnet. Glykoside und Aglykone sind ebenfalls leicht zu unterscheiden.
