Chem. [f. as TURACIN; cf. biliverdin.] A green coloring-matter occurring in the feathers of some Touracos.
1885. Riverside Nat. Hist. (1888), IV. 5. A really green pigment has only been found in the touracos—hence the name turacoverdin.
1892. A. H. Church, in Phil. Trans., CLXXXIII. 512. Dr. C F. W. Krukenberg … has described a green colouring matter obtained from the green feathers of Turacus corythaix, and of other plantain-eaters, by the employment of a 2 per cent. caustic soda-solution as the solvent. He calls this pigment ‘turacoverdin,’ and … states that it contains ‘much iron, but no great quantity of copper and manganese.’
