Delphinidin (also delphinidine[1][2]) is an anthocyanidin, a primary plant pigment, and also an antioxidant.[3] 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,[4] and bilberries.[5]

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


Several glycosides derived from delphinidin are known:

  • Violdelphin (delphinidin 3-rutinoside-7-O-(6-O-(4-(6-O-(4-hydroxybenzoyl)-β-D-glucosyl)oxybenzoyl)-β-D-glucoside) is responsible for purplish blue flower color of Aconitum chinense.[6]
  • Nasunin (delphinidin-3-(p-coumaroylrutinoside)-5-glucoside) is responsible for the colour of the eggplant fruit purple skin.[7]
