The sumac fruits pericarp owes its dark red colour to anthocyanin pigments, of which chrysanthemin, myrtillin and delphinidin have yet been identified.

Delphinidin, like nearly all other anthocyanidins, is pH-sensitive, ie . a natural pH indicator, and changes from red in acidic solution to blue in basic solution.

Violdelphin is an anthocyanin, a type of plant pigments, found in blue flowers and incorporating two p-hydroxy benzoic acid residues, one rutinoside and two glucosides associated with a delphinidin.

The various colors, such as red, mauve, purple, violet and blue, in " Hydrangea macrophylla " are developed from one simple anthocyanin, delphinidin 3-glucoside foming complexes with metal ions.
15.
It is rich in flavonoids, such as anthocyanins, flavonols and flavanols, catechins, delphinidin 3-glucoside, cyanidin 3-glucoside, ellagic acid, and rutin; other analysis revealed the presence of gallo-and / or ellagitannins ).
16.
The various colors, such as red, mauve, purple, violet and blue, in " H . macrophylla " are developed from one simple anthocyanin, delphinidin 3-glucoside ( myrtillin ), which forms complexes with metal ions called metalloanthocyanins.

Gentian blue petals predominantly contain the unusually blue and stable anthocyanin gentiodelphin ( delphinidin 3-O-glucosyl-5-O-( 6-O-caffeoyl-glucosyl )-32-O-( 6-O-caffeoyl-glucoside ) ).

Major anthocyanins in blackcurrant pomace are delphinidin-3-O-glucoside, delphinidin-3-O-rutinoside, cyanidin-3-O-glucoside, and cyanidin-3-O-rutinoside which are retained in the juice concentrate among other yet unidentified polyphenols.

Researchers in Japan have genetically manipulated roses by using RNA interference to knock out endogenous DFR, adding a gene DFR from an iris, and adding a gene for the blue pigment, delphinidin, in an effort to create a blue rose, which is being sold worldwide.
