Fuchsine

 

(also Magenta I, or rosaniline hydrochloride), C20H20N3Cl, a triphenylmethane dye. One of the first synthetic dyes, it was obtained in 1856 by J. Natanson. It is called fuchsine because its color resembles that of the flowers of the fuchsia plant. Fuchsine occurs as crystals that are dark violet in transmitted light and green in reflected light. The crystals are sparingly soluble in water but readily soluble in alcohol; their aqueous solutions are bright red.

Fuchsine is not used in the modern textile industry because of its poor photostability. Certain fuchsine derivatives, such as Basic Violet 14, are used in the manufacture of pencils, carbon paper, and inks, including inks for ballpoint pens.

We have earlier shown that sputum in its containers can be stained (11), in an hour, by phenol ammonium sulphate basic fuchsin solution and its smear can then be decolourised and counter-stained for detection of acid-fast bacilli (AFB) (12,13).

The present study was undertaken with the objective to stain sputum samples in their containers by 'phenol (10%) ammonium sulphate (4%) basic fuchsin (2%) solution' and to decolourize and counterstain their smears for detection of AFB- (henceforth called pot method) and to compare the smear results of pot method with the standard Ziehl-Neelsen (ZN) method.
