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.
p-Coumaroylated anthocyanins are a type of anthocyanins with a p-coumaric acid unit linked with a sugar to an anthocyanidin aglycone. 3-(6-p-Coumaroyl)glucosides are found in grape and wine. Cyanidin-3- O -(di- p -coumarylglucoside)-5-glucoside is found in dark opal basil .
Callistephin is an anthocyanin. It is the 3-O-glucoside of pelargonidin. It is found in pomegranate juice, [2] in strawberries, [3] and in purple corn. [4] It is also found in the berry skins of Cabernet Sauvignon and Pinot Noir grapes (Vitis vinifera L.). [5]
Flavonoids can be further divided into groups based on their similar chemical structure, such as anthocyanins, flavones, flavanones, isoflavones, and flavanols. [5] [7] Flavanols are further classified as catechins, epicatechins, and proanthocyanidins. [5] [7] In total, between 50,000 [8] and 130,000 [9] phytochemicals have been discovered.
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.

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 ...
