title: [A method for the preparation and purification of the two blue main components of sudan black B (author's transl)].
abstract: Two dimensional thin layer chromatography of four commercial samples of Sudan Black B reveals two blue main components (SSB I and II) and at least 38 further fractions. The quantitative composition of one sample was estimated. SSB-I and SSB-II were isolated and purified by column chromatography supplying amounts for histochemical use. Histochemical experiments are described.
