hematoxylin

 [he″mah-tok´sĭ-lin]
an acid coloring matter obtained from the wood of a tree (Haematoxylon campechianum); used as a stain for histologic specimens and as an indicator.

he·ma·tox·y·lin

(hē'mă-toks'i-lin, hem-ă-), [C.I. 75290]
A crystalline compound, containing the coloring matter of Haematoxylon campechianum (logwood). It is used as a dye in histology, especially for cell nuclei and chromosomes, muscle cross-striations, and enterochromaffin cells; its staining properties depend on its oxidation to hematein and mordanting with chrome and iron alums. It is also used as an indicator (red to yellow at pH 0 to 1, yellow to violet at pH 5 to 6).

hematoxylin

/he·ma·tox·y·lin/ (he″mah-tok´sĭ-lin) an acid coloring matter from the heartwood of Haematoxylon campechianum; used as a histologic stain and also as an indicator.

(hē'mă-toks'i-lin)
[CI 75290] A crystalline compound containing the coloring matter of Haematoxylon campechianum (logwood), from which it is obtained by extraction with ether. It is used as a dye in histology, especially for cell nuclei and chromosomes, muscle cross-striations, and enterochromaffin cells, and as an indicator (red to yellow at pH 0.0-1.0, yellow to violet at pH 5.0-6.0).
