Detection and Structural Characterization of Nucleophiles Trapped Reactive Metabolites of Limonin Using Liquid Chromatography-Mass Spectrometry

Figure 1

Extract ion (m/z 956 → 817) chromatograms obtained from LC-LTQ MS analysis of microsomal incubations containing LIM, GSH, NAL, and NADPH in the absence microsomes (a), or in presence of HLMs (b) or MLMs (c). (d) Extracted ion (m/z 956 → 817) chromatogram obtained from LC-LTQ MS analysis of synthetic M1 and M1′. (e) MS/MS spectrum of M1 generated in microsomal incubations (M1′ showed the same MS/MS spectrum). (f) MS/MS spectrum of synthetic M1 (synthetic M1′ showed the same MS/MS spectrum).
