Malvidin is an O-methylated anthocyanidin, the 3',5'-methoxy derivative of delphinidin. As a primary plant pigment, its glycosides are highly abundant in nature.
Natural occurrences[]
Malvidin is responsible for the blue color found in petals of the Primula plants of the polyanthus group. Blue flowers of the blue pimpernel (Anagallis monelli) have also a higher concentration of malvidin.
It is responsible primarily for the color of red wine, Vitis vinifera being one of its sources.[1] It is also present in other berries, such as blueberries (Vaccinium corymbosum) or the saskatoon berries (Amelanchier alnifolia).[2][3]
Chemistry[]
Slightly acidic and neutral solutions of malvidin are characteristically of a red color, while basic solutions of malvidin yield a blue color.
The breakdown of malvidin releases syringic acid.
Use as a marker in archaeology[]
The breakdown of malvidin releases syringic acid as revealed in the examination of jars containing shedeh, a drink of Ancient Egypt. Malvidin is also present in the site of the Areni-1 winery, a 6,100-year-old winery discovered in 2007 in the Areni-1 cave complex in the village of Areni in the Vayots Dzor province of Armenia.
