|Section2= |Section3= }} Delphinidin (also Delphinidine〔 〕) 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. Delphinidin, like nearly all other anthocyanidins, is pH-sensitive, and changes from red in acidic solution to blue in basic 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 purplish blue flower color of ''Aconitum chinense''. Nasunin (delphinidin-3-(p-coumaroylrutinoside)-5-glucoside) is responsible for the colour of the eggplant fruit purple skin.〔Antioxidant activity of nasunin, an anthocyanin in eggplant peels.
