(organic chemistry)
C16H14O6 A colorless, crystalline compound occurring in hematoxylon; upon oxidation, it is converted to hematein which forms deeply colored lakes with various metals; used as a stain in microscopy.

Hematoxylin

 

a dye used in microscopy for staining plant and animal tissues. Hematoxylin is extracted by ether from the colored wood of the logwood tree, which is native to Central America and the Antilles Islands. In the course of its preparation for use in microscopy, the substance is “matured,” or oxidized to hematein, which stains cell nuclei, chromosomes, and cell membranes a blue or blue-black color.
