Fig. 2 in Carotenoid profiles of red- and yellow-colored arils of cultivars of Taxus baccata L. and Taxus × media Rehder

Fig. 2. ESI(+)-MS2 spectra of the compounds 19 and 21 from the arils of cultivars of Taxus baccata L. and Taxus × media Rehder assigned to (all-E)- rhodoxanthin (a) and (all-E)-eschscholtzxanthin (b), respectively. Proposed mass fragmentation of eschscholtzxanthin (c) and the formation of resonancestabilized in-source fragments as shown for eschscholtzxanthin and eschscholtzxanthin myristate (d) (Ziegler et al., 2015; Breithaupt et al., 2002; Enzell and Back, 1995).
