Determination of malachite green and leucomalachite green in edible goldfish muscle by liquid chromatography–ion trap mass spectrometry

Liquid chromatography–tandem mass spectrometry method for the determination of dye residues in aquaculture products: Development and validation

“…Several published methods have been developed for the analysis of MG, CV, BG and their metabolite in fish. Among the most recent of them, some use an oxidation step to transform the leuco forms in the parent forms allowing to detect the compounds in a unique parent form with liquid chromatography and detection in visible spectrum for the screening step or mass spectrometry detection for the confirmatory step [2][3][4][5][6][7] Other methods allow the determination of the compounds in their generic form, without post-column oxidation, using in that case liquid chromatography coupled to mass spectrometry for the detection [8][9][10][11].…”

Determination of malachite green in fish based on magnetic molecularly imprinted polymer extraction followed by electrochemiluminescence

“…The fish sample extraction method used in this study was according to a previous publication [32] with minor modifications. 5.0 g of homogenized tissue or 5.0 g of spiked sample (homogenized blank tissue sample was spiked with MG and LMG at different mass ratios indicated in the text) was placed into a 50 mL Teflon centrifuge tube.…”

Effect of malachite green toxicity on non target soil organisms

“…Due to its pervasive use and high solubility in water, MG can be released into the environment by various sources. Studies have reported its carcinogenic (Lee et al, 2006), teratogenic (Culp et al, 1999) and reproductive abnormalities (Cha et al, 2001) spanning its effect from various fish to mammals (Srivastava et al, 2004). Moreover, it is also demonstrated that MG is highly persistent in the environment (Xie et al, 2012).…”
