Different derivatization procedures were assayed to simultaneously analyse iminosugars such as deoxynojirimycin (DNJ) or fagomine and other carbohydrates of low molecular weight by gas chromatography coupled to mass spectrometry (GC–MS) in Morus sp. Both oximation+ trimethylsilylation and oximation+ acetylation allowed the separation of target compounds, whereas trimethylsilyl (TMS) and acetylated derivatives showed several ...
