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.

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.

Cyanidin is a natural organic compound. It is a particular type of anthocyanidin. It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, 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 < 3, violet at pH 7-8, and blue at pH > 11. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. In a recent study, cyanidin was found to be a potent sirtuin 6 (SIRT6) activator.

Anthocyanidins are common plant pigments. They are the sugar-free counterparts of anthocyanins based on the flavylium ion or 2-phenylchromenylium, which is a type of oxonium ion. They form a large group of polymethine dye. In particular anthocyanidins are salt derivatives of the 2-phenylchromenylium cation, also known as flavylium cation. As shown in the figure below, the phenyl group at the 2-position can carry different substituents. The counterion of the flavylium cation is mostly chloride. With this positive charge, the anthocyanidins differ from other flavonoids. 31 monomeric anthocyanidins have been properly identified, most of the anthocyanins are based on cyanidin (30%), delphinidin (22%), and pelargonidin (18%), respectively. Altogether 20% of the anthocyanins are based on the three common anthocyanidins that are methylated. Around 3, 3, and 2% of the anthocyanins or anthocyanidins are labeled as 3-desoxyanthocyanidins, rare methylatedanthocyanidins, and 6-hydroxyanthocyanidins, respectively.

Delphinidin 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 that produces Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, and bilberries.

Peonidin is an O-methylated anthocyanidin derived from Cyanidin, and a primary plant pigment. Peonidin gives purplish-red hues to flowers such as the peony, from which it takes its name, and roses. It is also present in some blue flowers, such as the morning glory.

Anthocyanins are water-soluble vacuolar pigments that, depending on their pH, may appear red, purple, or blue. 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.

<i>p</i>-Coumaroylated anthocyanin class of chemical compounds

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. Red leaves of Perilla frutescens also accumulate cyanidin 3-(6-O-p-coumaroyl-β- D-glucoside)-5-(6-O-malonyl-β-D-glucoside).
