With regard to the investigation of the biosynthesis of the C₃₀-carotenoids in citrus fruits apocarotenoids with a methyl group shifted by one position (diapocarotenoids) were synthesized.Characteristical differences, especially in the 270-MHz-1H-NMR. spectra between the apo- and the diapocarotenoids are reported.The comparison of the natural pigments with the synthetic compounds proves that the natural products belong to the apocarotenoids as has been postulated earlier.
