From: Metabolome analysis of 20 taxonomically related benzylisoquinoline alkaloid-producing plants
Relative ion abundances in 20 plant species. Only masses corresponding to those expected for alkaloids, extracted from positive mode FTMS data, are shown. UPLC retention times (Rt) for each ion mass (m/z) are provided to distinguish identical masses, which presumably represent different structural isomers. Variability in ionization efficiencies should be considered when comparing abundances between different ions. Relative abundance scale (green-yellow-red) highlights quantitative differences for each mass across different species. Species abbreviations are defined in Table 1. Species are grouped according to family or tribe: (pink = Papaveroideae; purple = Fumarioideae; orange = Ranunculaceae; green = Berberidaceae; blue = Menispermaceae)
