Structure of commelinin, a blue complex pigment from the blue flowers of Commelina communis
نویسندگان
چکیده
The X-ray crystal structure of natural commelinin is investigated. The results demonstrate that commelinin is a tetranuclear (4 Mg(2+)) metal complex, in which two Mg(2+) ions chelate to six anthocyanin molecules, while the other two Mg(2+) ions bind to six flavone molecules, stabilizing the commelinin complex, a new type of supramolecular complex.

Blue metal complex pigments involved in blue flower color
The blue pigment of cornflower, protocyanin, has been investigated for a long time, but its precise structure was not entirely explained until recently. The molecular structure of the pigment was recently shown to be a metal complex of six molecules each of anthocyanin and flavone glycoside, with one ferric iron, one magnesium and two calcium ions by X-ray crystallographic analysis. The studies...

متن کاملIdentifying the structure of pigments used in the context of manuscripts related to Safavid period
Studying various aspects of the manuscripts may be important in explaining the actual values of work, and the ways of protecting these values. Therefore, in this research 10 paint samples (blue and red) from the five manuscripts related to Safavid period (16th century) were analyzed to explore their nature and structure. First, the related literature regarding the frequent types of the paints i...
