Aplicação

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

Ações bioquímicas/fisiológicas

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.

Journal - Association of Official Analytical Chemists, 73(6), 940-946 (1990-11-01)
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

Journal of AOAC International, 77(6), 1454-1460 (1994-11-01)
A laboratory trial was completed for a liquid chromatographic method that can quantitate leucogentian violet (LGV) in chicken fat at 10 ppb. With this method, LGV is isolated from the fat matrix by a series of liquid-liquid extractions. This trial

Journal of chromatography. B, Biomedical applications, 674(1), 125-131 (1995-12-01)
A sensitive analytical procedure for the determination of residues of leucogentian violet (LGV) and gentian violet (GV) in catfish tissue is presented. Frozen (-20 degrees C) catfish fillets were cut into chunks and then blended in a Waring blender. A

Journal of AOAC International, 77(5), 1137-1142 (1994-09-01)
A gas chromatographic/mass spectrometric (GC/MS) procedure for confirming the identity of leucogentian violet (LGV) in chicken fat was developed for regulatory application. The unused portion of the extract remaining from a determinative procedure was back-extracted into an organic phase, concentrated
Xueli Wu et al.
Journal of chromatography. A, 1172(2), 121-126 (2007-10-24)
A method has been developed for the simultaneous determination of malachite green, gentian violet and their leuco-metabolites in various aquatic products using isotope dilution liquid chromatography-linear ion trap mass spectrometry without post-column oxidation. Sample was extracted with McIlvaine buffer and
