| Abstract: | Neoxanthin has been isolated from petals of Helianthus annuus, Taraxacum officinale and Impatiens nolitangere. It is identical with authentic neoxanthin from Euglena gracilis. MS and IR spectra were recorded, showing typical fragmentation patterns of neoxanthin, and an allene group. A pigment with the properties of deepoxineoxanthin and polar xanthophylls, which absorbed at very short wavelengths, were also isolated. |
