Description:
Haematoxylin, hematoxylin, Natural Black 1, or C.I. 75290 is extracted from the bark of the logwood tree. When oxidized it forms haematein, a compound that forms strongly colored complexes with certain metal ions, notably Fe(III) and Al(III) salts. Metal-haematein complexes are used to stain cell nuclei prior to examination under a microscope. Structures that stain with iron- or aluminium-haematein are often called basophilic, even though the mechanism of the staining is different from that of staining with basic dyes.
