Carminic acid is a tetrahydroxyanthraquinone that is that is 1,3,4,6-tetrahydroxy-9,10-anthraquinone substituted by a methyl group at position 8, a carboxy group at position 7 and a 1,5-anhydro-D-glucitol moiety at position 2 via a C-glycosidic linkage. It is a natural dye isolated from several insects such as Dactylopius coccus. It has a role as an animal metabolite and a histological dye. It is a C-glycosyl compound, a monocarboxylic acid and a tetrahydroxyanthraquinone. It is a conjugate acid of a carminate(2-).
