1838 T. Thomson Chem. Org. Bodies 387 Madder, according to Kuhlmann, contains two colouring matters, one, which is yellow, is soluble in cold water. Kuhlmann, who first obtained it, has given it the name of xanthin.

1839 A. Ure Dict. Arts 1329 Xanthine, is the name given by Kuhlmann to the yellow dyeing-matter contained in madder.
