Anthocyanidins

Delphinidin (also delphinidine) is an anthocyanidin, a primary plant pigment, and also an antioxidant. Delphinidin gives blue hues to flowers in the genera Viola and Delphinium. It also gives the blue-red color of the grape variety Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, and bilberries.

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. It can also be found in other fruits such as apples and plums, and in red cabbage and red onion. It has a characteristic reddish-purple color, though this can change with pH; solutions of the compound are red at pH 11. In certain fruits, the highest concentrations of cyanidin are found in the

Pelargonidin is an anthocyanidin, a type of plant pigment producing a characteristic orange color used in food and industrial dyes.

Aurantinidin is a water-soluble, red plant dye. It is a member of the class of compounds known as anthocyanidins and is a hydroxy derivative of pelargonidin. Aurantinidin has been reported to occur in Impatiens aurantiaca (Balsaminaceae), and also in cultivars from genus Alstroemeria.

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 and in various myrtles, roselle plants, and Centella asiatica plant. It is also present in yeast and oatmeal. The sumac fruit's pericarp owes its dark red colour to anthocyanin pigments, of which chrysanthemin, myrtillin and delphinidin have yet been identified.

Robinetinidin is an anthocyanidin, a type of flavonoid.

Luteolinidin is a member of the 3-deoxyanthocyanidins. It is an orange pigment, found e.g. in Sorghum bicolor.

Fisetinidin is an anthocyanidin. It has been obtained from the heartwood of Acacia mearnsii, from the bark of Rhizophora apiculata and can also be synthesized. Fisetinidin is very similar in structure to fisetin, which itself differs in structure from quercetin only by an additional hydroxyl group on the latter.

Guibourtinidin is an anthocyanidin.

Tricetinidin is an intense red-colored chemical compound belonging to the 3-deoxyanthocyanidins. It can be found in black tea infusions. Tricetinidin, in tea, would be a product of the oxidative degallation of epigallocatechin gallate (EGCG).

6-Hydroxycyanidin is an anthocyanidin.

Columnidin is an orange red pigment, belonging to the 3-deoxyanthocyanidins found in red-flowered western-hemisphere gesneriad species such as episcias, columneas, sarmientas, and sinningias.

Apigeninidin (Also, apigenidin, or Gesneridin) is a chemical compound belonging to the 3-deoxyanthocyanidins and that can be found in the Patagonian plant Ephedra frustillata and in the soybean. Apigeninidin is one of the principal pigments found in sorghum. Extremely high level of apigeninidin (49 mg/g) has been documented in sorghum leaf sheath. Like all anthocyanidins it exists in a variety of tautomers depending on pH and hydration, several of these bare the distinctive pyrylium core.

Diosmetinidin is a 3-deoxyanthocyanidin.
