Metalloanthocyanin

A metalloanthocyanin is a chemical compound found in plant giving color to petals.

These complexes are self-assembled, supramolecular metal complex pigment composed of stoichiometric amounts of anthocyanins, flavones, and metal ions.^[1]

Examples

Commelinin, a blue pigment from the flowers of Commelina communis, is a complex of 4 Mg²⁺ ions chelating six anthocyanin molecules.^[2]

Cyanosalvianin, a blue pigment from the flowers of Salvia uliginosa, is a complex formed of six molecules of the anthocyanin type, six molecules of the flavone type and two magnesium ions.^[3]
