Delphinidin

Chemical compound

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 variety Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates,[4] and bilberries.[5]

Quick Facts Names, Identifiers ...

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

Glycosides

Several glycosides derived from delphinidin are known:

  • Myrtillin (delphinidin-3-O-glucoside) and tulipanin (delphinidin-3-O-rutinoside) can be found in blackcurrant pomace.
  • Violdelphin (delphinidin 3-rutinoside-7-O-(6-O-(4-(6-O-(4-hydroxybenzoyl)-β-D-glucosyl)oxybenzoyl)-β-D-glucoside) is responsible for the purplish-blue flower color of Aconitum chinense.[6]
  • Nasunin (delphinidin-3-(p-coumaroylrutinoside)-5-glucoside) is responsible for the colour of the eggplant fruit's purple skin.[7]
  • Delphinidin ternatins including Clitoria ternatea ternatins
