J. Planar Chromatogr. 14, 350-354 (2001). TLC of troleandomycin, tylosin, rifamycin B, vancomycin, erythromycin, and rifampicin on polyamide 11 plates with five binary solvent mixtures methanol - water, ethanol - water, propanol - water, acetonitrile - water, and tetrahydrofuran - water. Detection by spraying with anisaldehyde - methanol - acetic acid - orthophosphoric acid - sulfuric acid 1:100:10:10:5 and heating at 110°C for 10 min.
J. Planar Chromatogr. 18, 423-426 (2005). HPTLC of antibiotics (sulfadimidine, sulfadiazine, sulfaguanidine, trimethoprim) on silica gel without chamber saturation in a twin-trough chamber with chloroform - methanol 89:11. Quantification by videodensitometry at 254 nm. Limit of detection was 0.05 µg per spot for sulfadimidine, sulfadiazine, and sulfaguanidine, and 0.1 µg per spot for trimethoprim.
J. AOAC Int. 92, 1068-1075 (2009). TLC and HPTLC of six antibiotics (amikacin, gentamicin, kanamycin, neomycin, netilmicin, and tobramycin) in pharmaceutical preparations on silica gel with methanol - 25 % ammonia - chloroform 3:2:1. Detection by derivatization with 0.2 % ethanolic ninhydrin reagent. Quantitative determination by absorbance measurement at 500 nm. The limit of detection and quantification was 250 and 500 ng/zone for amikacin, 500 and 1000 ng/zone for kanamycin, 480 and 800 ng/zone for neomycin, 380 and 630 ng/zone for netilmycin, 480 and 800 ng/zone for tobramycin and 1000 and 1650 ng/zone for gentamicin. Precision was good with %RSD of 0.3-0.6 %.
J. AOAC Int. 94, 735-742 (2011). HPTLC and TLC of ofloxacin on silica gel with ethanol - conc. ammonia 4:1 in a horizontal chamber. Quantitative determination by fluorescence measurement at 313 nm. Simulated samples at a residue level of 1 mg/m² were prepared by spreading the calculated amount of ofloxacin solution on 1, 5, and 10 dm² stainless steel surfaces. The hRf of ofloxacin was 56. The mean recovery (n = 6) was 88.6-95.3 % with a CV of 3.8-4.9 %. The LOD was 0.6 ng/zone and the LOQ was 2 ng/zone, but it was shown that these can be lowered by immersion of the developed plate into a solution of liquid paraffin - n-hexane 1:2 to approximately 0.3 and 0.9 ng/zone. The repeatability (system precision) was 4.2 % for 2 ng, and 3.7 % for 20 ng. The recovery was between 88.6-95.3 %.
J. Liq. Chromatogr. Relat. Technol. 37, 2915-2918 (2014). HPTLC of danofloxacin on silica gel with methanol – acetone – 1M citric acid – triethylamine 28:20:2:5. Quantitative determination by absorbance measurement at 280 nm. The hRF value for danofloxacin was 30. Linearity was in the range of 1250-3750 ng/zone. The intermediate/interday/intra-day precisions were below 1 % (n=3). The LOD and LOQ were 1.3 and 3.8 ng/zone, respectively. Recovery was in the range of 97.3-95.6 %.
J. Liq. Chromatogr. Relat. Technol. 38, 1126-1130 (2015). HPTLC of pyrazinamide (1), ethambutol (2), isoniazid (3),_x000D_ and rifampicin (4) on silica gel with methanol - toluene - ammonia 24:20:1 for (2) and ethyl acetate - acetone - methanol - acetic acid 5:2:2:1 for (1), (2) and (4). Quantitative determination by absorbance measurement at 254 nm. The method is designed to apply sample and standard weights and use mobile phases and detection methods similar to the Minilab methods.
J. Planar Chromatogr. 30, 126-130 (2017). TLC–direct bioautography of various hop varieties (Humulus lupulus L.) on silica gel with dichloromethane – acetonitrile 4:1 for ethanolic extracts and acetonitrile – methanol – dichloromethane 5:2:3 for aqueous extracts. The TLC plate was immersed in the bacterial suspension using the strains B. subtilis (ATCC 6633) and E. coli (ATCC 25922) and incubated under typical conditions.
VI. Detection reagents for tetracyclines in thin-layer chromatography. J. Chromatogr. 295, 129-139 (1984). HPTLC of various tetracyclines on silica with lower layer of chloroform - methanol -5 % Na2 EDTA sol. 65:20:5 and RP-TLC with chloroform - acetonitrile - 0.5 M oxalic acid sol. (pH 2.0) 1:1:2 or 1 :1:4. Detection with 1 % Fast Violet B salt solution. Dual wavelength mode densitometry at 366/600 nm and 425/650 nm. Detection limit 50 ng.
