Figure 10-14. Analysis of cherry pit oil using ESI-HRAM-MS on Q Exactive orbitrap instrument as part of comprehensive LC1MS2 x LC1MS2 (LC2MS4) analysis. (A) Total ion current chromatogram (TIC); (B) extracted ion chromatogram (EIC) of full scans; (C) mass spectrum of LElL showing [M + NH4]+ adduct; (D) LLO; (E) OOO; (F) MS/MS of [M + NH4]+ of LLEl at m/z 894.75; (G) MS/MS of [LLO + NH4]+ m/z 898.79; and (H) MS/MS of [OOO + NH4]+ m/z 902.815. Abbreviations are given in Fig. 10.6. El, eleostearic acyl chain, (9Z,11E,13E)18:3. ESI, electrospray ionization; HRAM, high-resolution accurate-mass; MS, mass spectrometry. Labels are regiospecific at sn-2. Thanks to Dharma Kodali and Lucas Stolp for CPO sample.
