Alkanna tinctoria

Carmine belongs to the anthraquinone class of compounds and several other chemically closely related compounds are also used as colorants.25 Kermes is a well known colorant in Europe. It is obtained from the insects, Kermes ilicis or Kermococcus vermilis, which grow on oak trees. It contains kermisic acid, the aglycone of carminic acid, and its isomer ceroalbolinic acid. Its properties are very similar to carmine. Lac is a red colorant obtained from the insect Laccifera lacca which is found on several families of trees in India and Malaysia. The lac insects are better known for their production of shellac. They contain a complex mixture of anthraquinones. Alkanet is a red pigment from the roots of Alkanna tinctoria Taush and Alchusa tinctoria Lom. All three have been cleared for food use in Europe but not in the US.

The roots of alkanet, also known as common bugloss Alkanna tinctoria, syn. Anchusa tinctoria, Boraginaceae) growing in the south of Europe, contain the reddish pigment alkannin (alkannet, 9-151) that was used as a textile dye. The (S)-isomer of alkannin is used today as a food colouring E103 to impart colour to ice creams, sweets and other products. The red (R)-isomer called shikonin was isolated from the roots of the medicinal plant Lithospermum erythrorhizon of the same family, which is native to China. 

A naphthoquinone dyestuff which is the secondary colouring matter derived from the roots of the plant Alkanna lehmannii Tineo (formerly known as Alkanna tinctoria Tausch. and commonly Alkanet, q.v.) (Schweppe, 1992). It is catalogued by the Colour Index (1971) as Cl 75520. 

A group of natural and synthetic dyestuffs based on the naphthoquinone structure (phenolic) have found use in the formation of lake and other pigments. Naphthoquinones are found in the leaves, blossoms, wood, bark, roots and fruit of about 20 different species. Those which are found in pigment use are AUcannin and Alkannan in AUcanet from plant species such as Alkanna lehmannii Tineo (formerly known as Alkanna tinctoria Tausch.), Macrotomia spp., Onosma spp. and juglone in Walnut qq.v.) fiom Juglans spp.

ALKANET (Alkanna) — An ancient dyestuff in the form of a dark red amorphous powder, prepared from the roots of Alkanna tinctoria. It exhibits a green iridescence is used by natives in the East for dyeing the nails, teeth, hair, and garments also colouring oils red.
