Liquid chromatography with ultraviolet detection of lasalocid, monensin, salinomycin and narasin in poultry feeds using pre-column derivatization

Resistance to anticoccidial drugs of Dutch avian Eimeria spp. field isolates originating from 1996, 1999 and 2001

“…Data on the proportions and concentrations of the extraction mixtures, which vary according to the product to be analysed, can be found in the corresponding references of lasalocid, monensin, salinomycin and narasin (Dusi & Gamba, 1999), clopidol (Dusi et al ., 2000), halofuginone (Tiller et al , 1988), diclazuril (De Kock et al ., 1992), maduramicin (Gliddon et al ., 1988), and nicarbazin (Hurlbut et al ., 1985).…”

Simultaneous Determination of Residual Veterinary Drugs in Bovine, Porcine, and Chicken Muscle Using Liquid Chromatography Coupled with Electrospray Ionization Tandem Mass Spectrometry

“…Several methods have been reported for the simultaneous determination of veterinary drugs in muscle. [3][4][5][6][7][8][9][10] Most of these methods were developed with the intention of determining analogous compounds, [5][6][7][8][9][10][11][12][13][14] and there are scarcely any reports on methods developed with the intention of simultaneous determination of compounds belonging to various classes. Liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC/MS/MS) affords a highly specific method of determining various compounds by providing structural information.…”

Polymeric Micelles of PEG-PLA Copolymer as a Carrier for Salinomycin Against Gemcitabine-Resistant Pancreatic Cancer

“…Thus, pre-column derivatization with 2,4-dinitrophenyl-hydrazine was used in order to improve its detection according to previously established method (18).…”
