“…The (+) APCI/Orbitrap mass spectra showed pseudomolecular ions ([M + H] + ) at m / z 411.3985, 409.3829, 545.5081, and 547.5237 for squalene, dehydrosqualene, phytoene, and hydrogenated phytoene (lycopersene), respectively. Their MS/MS behaviors were identical to previous reports: m / z 545 → 137, 81, and 69 for phytoene; m / z 547 → 137, 121, and 69 for lycopersene; m / z 409 → 326, 299, 215, and 159 for dehydrosqualene; and m / z 411 → 329, 287, 259, 231, 149, 109, and 69 for squalene, − as depicted in Figure and Figures S1–S4.…”
