Report of the ... Meeting
When the red solution is cautiously evaporated, a substance of a dark violet
colour is deposited ; this body is hematein- ammonia. Hematein is analogous to
orcein, phloridzein, &c. j it dissolves in water with a purple colour ; by evaporating
the ...

Report of the Annual Meeting
Hematein is analogous to orcein, phloridzein, &c. ; it dissolves in water with a
purple colour ; by evaporating the solution, the whole of the ammonia is expelled,
and pure hematein remains. Hematein differs from orcein in containing no
nitrogen ...

Theory and Practice of Histological Techniques
The major oxidization product is hematein, a natural dye that is responsible for
the color properties. Hematein can be produced from hematoxylin in two ways:
Natural oxidation ('ripening') by exposure to light and air. This is a slow process, ...

Hematein is produced by oxidation of hematoxylin. Oxidation is reversible, and is
brought about by the use of chemical oxidizing agent,e.g.sodium iodate, or by
exposure to light and air(«ripening»). IO3-+ 3 Hematoxylin (2H) —> 3 Hematein +

Visualization of Nucleic Acids
It is extracted from Haematoxylus compechianus, a South American tree.
Hematoxylin (Structure 2) is not a dye in itself. Its oxidative product, hematein (
Structure 3) is what is used for staining nucleic acids. The oxidation of
hematoxylin can be ...

Tissue Engineering: Principles and Practices
The extracted form of hematoxylin is not endowed with staining ability until it has
been oxidized into hematein. There are two common methods used for the
oxidation. “Ripening” is one strategy that leaves hematoxylin in the air and under
light, ...

The use of chemical oxidizing agents converts the hematoxylin to hematein
almost instantaneously, so these hematoxylin solutions are ready for use
immediately after preparation. In general, they have a shorter useful life than the
naturally ...
