无色结晶紫用于鉴别干酪中产生组胺的乳酸菌。
Biochem/physiol Actions
无色结晶紫 (LCV) 是一种阳离子三芳甲烷染料。LCV 是龙胆紫（结晶紫）的还原形式，因此，它是无色的。对纤维素和蛋白质材料均有亲和力。LCV 和过氧化氢与血液中的血红蛋白发生反应，使血液印记变为紫色/紫罗兰色。因此，该染料广泛用于染色多孔和无孔材料上的血液残留物。

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 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

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
