A survey of metalloanthocyanin by in vivo visible spectrum and circular dichroism suggested that blue petals of Salvia macrophylla contain metalloanthocyanins. Chemical analysis of the purified blue pigment proved that the pigment in the petals is protodelphin, which is the same pigment present in the blue petals of Salvia patens composed of malonylawobanin, apigenin 7,4'-diglucosides and Mg2+.
