Alkannin
Alkannin is a natural dye that is obtained from the extracts of plants from the borage family Alkanna tinctoria that are found in the south of France. The dye is used as a food coloring and in cosmetics. It is used as a red-brown food additive in regions such as Australia, and is designated in Europe as the E number E103, but is no longer approved for use. The chemical structure as a naphthoquinone derivative was first determined by Brockmann in 1936. Alkannin has a deep red color in a greasy or oily environment and a violet color in an alkaline environment.
