Useful plants of dermatology. Alizarin red and madder.
J Am Rubia tinctorum Dermatol ;39 3: On the history and mechanism of alizarin and alizarin red S stains for calcium. By drying, fermenting or a treatment with acids, this is changed to sugar, alizarin and purpurinwhich were first isolated by the Rubia tinctorum chemist Pierre Jean Robiquet in Purpurin is normally not coloured, but is red when dissolved in alkaline solutions.
Mixed rubia tinctorum clay and treated with alum and ammoniait gives a brilliant red colourant rubia tinctorum lake. The pulverised roots can be dissolved in sulfuric acidwhich leaves a dye called garance the French name for madder after drying.
Another method of increasing the yield consisted of dissolving the roots in sulfuric acid after they had been used for dyeing.

This produces a dye called garanceux. It is said that Madder can be used as fodder for animals.
Other Uses Madder root contains the anthraquinone pigment alizarin and has been since ancient times a popular fine red dye plant.
The long rubia tinctorum root, when dried rubia tinctorum milled, yields a variety of brilliant colors: This feature enables them to be used for polishing metalwork[4, ].
MADDER (Rubia tinctorum)
Cultivation rubia tinctorum Prefers a light sandy rubia tinctorum in full sun. Plants grown in fertile well-limed soils produce more pigment in the root. This plant was at one time widely cultivated for the red dye obtained from its roots, this dye is now manufactured chemically.
However, it is still cultivated in Europe as a medicinal dye plant. The plant produces many side roots that can travel just under the surface of the soil for some distance before sending up new shoots. Component s with potential cancer hazard 1-hydroxyanthraquinone; 1,3-dihydroxyhydroxymethylanthraquinone lucidin 1.
Rubia tinctorum L.
Structural and molecular formulae and relative molecular mass 1-Hydroxyanthraquinone 1. Chemical and physical properties of the pure substance 1-Hydroxyanthraquinone Melting-point: Analysis A method using reversed-phase high-performance rubia tinctorum chromatography HPLC has been described that allows the separation of 13 naturally occurring naphthoquinones and anthraquinones, including 1-hydroxyanthraquinone.
The separation was achieved under isocratic and gradient conditions Steinert et rubia tinctorum. The following method has been used to determine hydroxyanthraquinones in experimental laboratory animal diet containing madder.
Rubia tinctorum were isolated by Soxhlet extraction with ethyl acetate, evaporation of the solvent, and dissolution in methanol. Separation of the hydroxyanthraquinones was accomplished by HPLC with spectrometric detection at nm Westendorf et al.
Lucidin content in R.
An HPLC method with isocratic elution has been developed for the separation of anthraquinones with particular attention to the detection of lucidin in commercially available sources of R. A reversed-phase HPLC method has been developed for the simultaneous characterization of anthraquinone glycosides and aglycones in extracts of R.
Rubia tinctorum anthraquinones, including lucidin, are separated on a reversed-phase column with a water—acetonitrile gradient as eluent and measured with ultraviolet detection at nm Krizsan et al. Production 1-Hydroxyanthraquinone has been synthesized by diazotization of rubia tinctorum and heating the diazonium salt with concentrated sulfuric acid.
