The anthocyanins are subdivided into the sugar-free anthocyanidin aglycones and the anthocyanin glycosides. [ citation needed ] As of 2003, more than 400 anthocyanins had been reported, [ 53 ] while later literature in early 2006, puts the number at more than 550 different anthocyanins.
Myrtillin is an anthocyanin. It is the 3-glucoside of delphinidin. It can be found in all green plants, most abundantly in black beans, blackcurrant, blueberry, huckleberry, bilberry leaves [1] [2] and in various myrtles, roselle plants, and Centella asiatica plant. [citation needed] It is also present in yeast and oatmeal.
Blue color inflorescences of Hydrangea macrophylla. A metalloanthocyanin is a chemical complex giving color to petals of certain plants.. These complexes are self-assembled, supramolecular metal complex pigment composed of stoichiometric amounts of anthocyanins, flavones, and metal ions.
Plant pigments include a variety of different kinds of molecule, including porphyrins, carotenoids, anthocyanins and betalains. All biological pigments selectively absorb certain wavelengths of light while reflecting others.
In bryophytes, anthocyanins are usually based on 3-desoxyanthocyanidins located in the cell wall. A new anthocyanidin, riccionidin A, has been isolated from the liverwort Ricciocarpos natans . It could be derived from 6,7,2′,4′,6′-pentahydroxyflavylium, having undergone ring closure of the 6’ -hydroxyl at the 3-position.

The characteristic floral jade coloration of Strongylodon macrobotrys has been shown to be an example of copigmentation, a result of the presence of malvin (the anthocyanin) and saponarin (a flavone glucoside) in the ratio 1:9. [3] Berries. It is a phenomenon observed in the berry color of the porcelain berry (Ampelopsis glandulosa). Food
Anthocyanins chemical structure, carbon 3 is represented as the R3 group Luteolinidin chemical structure. The 3-Deoxyanthocyanidins and their glycosides (3-deoxyanthocyanins or 3-DA) are molecules with an anthocyanidins backbone lacking an hydroxyl group at position 3 on the C-ring. This nomenclature is the inverse of that which is commonly ...
