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 ...
Parsley is a source of flavones Blueberries are a source of dietary anthocyanins Flavonoids are found in citrus fruits, including red grapefruit Flavonoids (specifically flavanoids such as the catechins ) are "the most common group of polyphenolic compounds in the human diet and are found ubiquitously in plants".
These complexes are self-assembled, supramolecular metal complex pigment composed of stoichiometric amounts of anthocyanins, flavones, and metal ions. The various colors, such as red, mauve, purple, violet and blue, in Hydrangea macrophylla are developed from one simple anthocyanin, delphinidin 3-glucoside forming complexes with metal ions.
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]
