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.

Primulin is an anthocyanin. It is the 3-galactoside of malvidin. It can be found in Primula sinensis. [2] The first crystalline form of this pigment was prepared by Rose Scott-Moncrieff in about 1930. This was the first crystalline anthocyanin pigment ever identified. This was possible because of her insight into linking genetics with chemistry ...
Cyanidin is a natural organic compound.It is a particular type of anthocyanidin (glycoside version called anthocyanins).It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, chokeberry, cranberry, elderberry, hawthorn, loganberry, açai berry and raspberry.

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 .
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".
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]
