Abstract

Reconstruction, not decomposition, was used to determine the composition of the pigment from the blue petals of cornflowers, protocyanin. Comparison of optical and mass spectra of natural and reconstructed protocyanin revealed it to be a complex of an anthocyanin and a malonylflavone with iron(III) and magnesium ions.
