Chemistry.

1848 E. Schunck in Rep. Brit. Assoc. Advancem. Sci. 1847 136 Of the two colouring matters, one is Robiquet's Alizarin, and the other I shall call Rubiacin.

1868 H. Watts Dict. Chem. (at cited word) Rubiacin is found partly in the precipitate produced by acids in the decoction of madder, partly in the residue left after exhausting the root with water.

1918 A. G. Perkin & A. E. Everest Nat. Org. Colouring Matters i. 31 Rubiacin (Runge's madder orange) is a yellow crystalline substance obtained directly from the madder root.

1975 Ambix 22 151 Rubiacine... The elementary composition,..UV spectrum, melting point.., all agree with those of 1,3 dihydroxy 2 formyl anthraquinone (nordamnacanthal).

1998 M. Tierra & L. Tierra Chinese Trad. Herbal Med. II. 157 Other colors from different species [of madder] are purpurin for purple, rubiacin for orange and xanthin for yellow.
