Definition: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.
Synonyms:exact_synonym: (1S)-1,5-anhydro-1-(7-carboxy-1,3,4,6-tetrahydroxy-8-methyl-9,10-dioxo-9,10-dihydroanthracen-2-yl)-D-glucitol
