The present review compiles positive MS fragmentation data of selected carotenoids obtained using various ionization techniques and matrices. In addition, new experimental data from the analysis of carotenoids in transgenic maize and rice callus are provided. Several carotenes and oxygen-functionalized
carotenoids containing epoxy, hydroxyl, and ketone groups were ionized by atmospheric pressure chemical ionization (APCI)-tandem mass spectrometry (MS/MS) in positive ion mode. Thus, on the basis of the information obtained from the literature and our own experiments, we identified characteristic carotenoid ions that can be associated to functional groups in the structures of these compounds. In addition, pigments with a very similar structure were differentiated through comparison of the intensities of their fragments. The data provide a basis for the structural elucidation of carotenoids by mass spectrometry (MS).

Rivera Vélez, Sol Maiam; Canela i Garayoa, Ramon (Elsevier, 2012)High-performance liquid chromatography (HPLC) has become the method of choice for carotenoid analysis. Although a number of normal-phase columns have been reported, reverse-phase columns are the most widely used stationary ...

The analysis was carried out using an ultrahigh-pressure liquid chromatograph coupled to a photodiode array detector and a mass ...
A novel carotenoid, 4-keto-a-carotene, as an unexpected by-product during genetic engineering of carotenogenesis in rice callus Breitenbach, Jürgen; Bai, Chao; Rivera Vélez, Sol Maiam; Canela i Garayoa, Ramon; Capell Capell, Teresa; Christou, Paul; Zhu, Changfu; Sandmann, Gerhard (Elsevier, 2014)Rice endosperm is devoid of carotenoids because the initial biosynthetic steps are absent. The early carotenogenesis reactions were constituted through co-transformation of endosperm-derived rice callus with phytoene ...
