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.

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.
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 ...
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.

Leucoanthocyanidin (flavan-3,4-diols) are colorless chemical compounds related to anthocyanidins and anthocyanins.Leucoanthocyanins can be found in Anadenanthera peregrina and in several species of Nepenthes including N. burbidgeae, N. muluensis, N. rajah, N. tentaculata, and N. × alisaputrana.
This is done by the 3GT, anthocyanin 3-O-glucosyltransferase gene. [6] Pelargonidin 3-glucoside. However this glucosidation reduces its antioxidant activity, [7] and changes the wavelength of max light absorbance from 520 nm to 516 nm. [8] Acylated pelargonidin glycosides can be found in red-purple flowers of Ipomoea purpurea. [9]
