Analysis of Acyl Solamines in Tuber Periderm of Cultivated and Wild Potatoes Using Liquid Chromatography Coupled With Electrospray Ionization Quadrupole Time-of-Flight Mass Spectrometry.

ABSTRACT: Acyl solamines are a poorly investigated class of alkaloids found in several solanaceous plants. A general screening approach on the basis of all-ion fragmentation is proposed for this compound class using reversed-phase ultra-high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry. When applied to tuber periderm extracts of Solanum tuberosum, Solanum pinnatisectum, and Solanum cardiophyllum, this approach resulted in the annotation of over 20 acyl solamines including short- and medium-chain fatty acyl solamines, hydroxycinnamoyl solamines, and other aromatic acyl solamines. In addition, minor derivatives with N-oxidized solamine moieties (acyl solamine-N-oxides and di-N-oxides) and N-demethylated solamine moieties (acyl nor-
