Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins. [1] [2] Anthocyanins belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway.
Juglone is an example of such a molecule inhibiting the growth of other plant species around walnut trees. [ citation needed ] The aquatic vascular plant Myriophyllum spicatum produces ellagic , gallic and pyrogallic acids and (+)- catechin , allelopathic phenolic compounds inhibiting the growth of blue-green alga Microcystis aeruginosa .
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.
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.

Anthocyanins are most visible in the petals of flowers of many species. [5] Plants, in general, contain six ubiquitous carotenoids: neoxanthin, violaxanthin, antheraxanthin, zeaxanthin, lutein and β-carotene. [7] Lutein is a yellow pigment found in fruits and vegetables and is the most abundant carotenoid in plants.
Another study of nearly 2,000 women found anthocyanins and flavonoids, abundant in cranberries, may reduce cardiovascular disease risk. The beneficial plant compounds may also help prevent ...
Ideain is the main anthocyanin in red-skinned [1] or red-fleshed (for example Weirouge) [2] apple varieties. It is also found in Chinese hawthorn fruits (Crataegus spp.). [3]It is also the pigment in the copper beech (cultivar of Fagus sylvatica), that was identified in 1932.
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.
