Part XIX: Determination of tetracycline antibiotics in milk by liquid chromatography and thin-layer chromatography / fast atom bombardment mass spectrometry. J. AOAC Int. 77, 891-895 (1994). TLC of oxytetracycline, tetracycline, chlortetracycline, doxycycline on RP-8 with methanol - acetonitrile - 0.5 M aqueous oxalic acid solution (pH 2.0) 1:1:4.

J. Planar Chromatogr. 22, 435-437 (2009). TLC of penicillins (benzylpenicillin, ampicillin, and amoxicillin) and cephalosporins (cephalexin, cefoperazone, ceftriaxone, cefixime, and cefadroxil) in powder extracts on silica gel (impregnated with 0.2 % ammonium chloride) with propanol - acetic acid 4:1 and butanol - acetic acid - water 4:1:2. Detection under UV light at 365 nm.

J. Liq. Chromatogr. Relat. Technol. 34, 920-927 (2011). TLC of flumequine in milk on silica gel with dichloromethane - methanol - 2-propanol - 25 % aqueous ammonia 3:3:5:2. Bioautography by dipping into an Escherichia coli bacteria suspension for 5 h at 37 ºC. After incubation, the plates were sprayed with 0.2 % MTT ([3-(4,5-dimethyldiazol-2-yl)-2,5 diphenyltetrazolium bromide] aqueous solution and incubated for about 30 min at 37 ºC. The new procedure gave better recoveries of flumequine residues from milk compared with the previous method.

J. Planar Chromatogr. 27, 113-119 (2014). HPTLC of sulphadiazine sodium (1) and trimethoprim (2) in medicated fish feed, fish tissues, and in their veterinary pharmaceutical formulation on silica gel with chloroform - toluene - ethanol - glacial acetic acid 9:9:2:2. Quantitative determination by absorbance measurement at 270 nm. The hRF values for (1) and (2) were 48 and 16, respectively. Linearity was in the range of 100-2000 ng/zone for (1) and 100-1000 ng/zone for (2). The intermediate/interday/intra-day precisions were below 3 % (n=3). Mean recoveries for (1) and (2) were 99.6 and 97.9 %, respectively.
