Delphinidin is an anthocyanidin, a primary plant pigment, and also an antioxidant.[1] Delphinidin gives blue hues to flowers like violas and delphiniums. 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.[2]
Delphinidin, like nearly all other anthocyanidins, is pH-sensitive, and changes from blue in basic solution to red in acidic solution.
[edit] Glycosides
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)-beta-D-glucosyl)oxybenzoyl)-beta-D-glucoside) is responsible for purplish blue flower color of Aconitum chinense.[3]
