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.

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.
Example of this kind of pigment is present in hydrangea sepals. Main anthocyanin here is delphinidin-3-glucoside what should result in the blue flower formation, but cultivars with red and pink flowers are also present. It is known that acidification of soil can cause change of the hydrangea flower colour from red/pink to blue/violet.
Phytochemicals are chemicals of plant origin. [1] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [2] [3] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators. [2]
Blue color inflorescences of Hydrangea macrophylla. A metalloanthocyanin is a chemical complex giving color to petals of certain plants.. These complexes are self-assembled, supramolecular metal complex pigment composed of stoichiometric amounts of anthocyanins, flavones, and metal ions.
