Anwendung

Leucocrystal Violet has been used to identify histamine-producing lactobacilli in cheese.

Biochem./physiol. Wirkung

Leucocrystal Violet (LCV) is a cationic triarylmethane dye. LCV is a reduced form of gentian violet (crystal violet) and thus, it is colorless. It has an affinity for both cellulosic and proteinaceous materials. LCV and hydrogen peroxide react with the hemoglobin in blood and turn the blood impression to purple/violet color. Therefore, the dye is widely used to stain blood residue on both porous and non-porous materials.

High-performance liquid chromatographic conditions are reported for the electrochemical detection (ED) of Gentian Violet, its demethylated metabolites, Leucogentian Violet and Methylene Blue. Gentian Violet, its demethylated metabolites and Leucogentian Violet were separated within 14 min on a cyano column eluted

A method is presented for determination of residues of gentian violet (GV), its demethylated metabolites (pentamethyl and tetramethyl), and leucogentian violet (LGV) in chicken tissue. The analytes are extracted from tissue with acetonitrile/buffer and partitioned into methylene chloride. Polar lipids
