he·ma·tox·y·lin

H0142200 (hē′mə-tŏk′sə-lĭn)n. A yellow or red crystalline compound, C₁₆H₁₄O₆·3H₂O, the coloring material of logwood, that is used in dyes, inks, and stains.

[New Latin Haematoxylon, a genus of plants (Greek haimato-, hemato- + Greek xylon, wood) + -in.]

he•ma•tox•y•lin

(ˌhi məˈtɒk sə lɪn)

n. a colorless or pale yellow, crystalline compound, C₁₆H₁₄O₆•3H₂O, the coloring material of logwood: used as a mordant dye and as an indicator. [1840–50; hemato- + Greek xýl(on) wood + -in¹] he`ma•tox•yl′ic (-ˈsɪl ɪk) adj.

Hematoxylin

hematoxylin

[‚hē·mə′täk·sə·lən] (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.

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).
