Malvidin

From Wikipedia, the free encyclopedia

Malvidin is an anthocyanidin. As a primary plant pigment, its glycosides are highly abundant in nature. It is primarily responsible for the color of red wine, Vitis vinifera being one of its sources. It is also one of the anthocyanidins responsible for the blue pigment found in the Primula polyanthus plant.

Slightly acidic and neutral solutions of Malvidin are characteristically of a red color, while basic solutions of Malvidin yield a blue color.
