J. Chromatogr. 290, 83-96 (1984). Reversed-phase thin-layer chromatographic conditions were investigated for nineteen peptide-type antibiotics with molecular weights between 102 and 25000 and of different chemical characteristics, to find mobile phases giving Rf values between 0.05 and 0.95. 27 different mobile phases were employed, representing three organic modifiers, three buffers and three pH values.

J.A.O.A.C. 68, 643-645 (1985). TLC of sterigmatocystin on silica with benzene - methanol - acetic acid 85:10:5. Detection by spraying with aluminium chloride and heating at 110 °C for 5 minutes, followed by repeated spraying with silicone - ether mixture and heating at 110 °C for about. 3 minutes. Quantitation by fluorescence densitometry. Detection limit 2 mg/kg, limit of determination 5 mg/kg.

Chinese J. Chem. World (Huaxue Shijie) 34, 25-27 (1993). TLC of roxithromycin on silica with dichloromethane - acetone - aqueous NH3 45:5:1, and dichloromethane - acetone - petrol ether - methanol - aqueous NH3 42:6:5:2:1. Detection by spraying with a cerium sulfate - sodium molybdate solution. Quantification by densitometry at 610 nm.

Microbiol. Res. 163, 161-167 (2008). Test solutions containing 0.25 to 64 µg of norharmane, quinine, and tetracycline (as bases and hydrochloride salts) were applied as 10 mm bands on silica gel plates. After coating the plate with a concentrated suspension of the living cyanobacterial test organism (spraying or dipping), it was kept moist in a TLC chamber at 27 ºC for 1 to 2 days under continuous illumination (25 - 30 µmol photon/m2s). Cytotoxic concentrations of a test compound resulted in an easily recognizable regional decolourisation of the test organism.

J. Liq. Chromatogr. Relat. Technol. 32, 3049-3055 (2009). HPTLC of cinoxacin (1), pipemidic acid (2), ofloxacin (3), and pefloxacin (4) on silica gel with buffer solution (pH 5.5) - methanol 4:1 and acetonitrile - water - acetic acid, 3:20:2. Detection by dipping into various visualization agents. The detection limits for (1) to (4) were 0.1, 0.1, 0.5, and 0.75 µg/zone, respectively. Best detection conditions for (1) and (2) were obtained by dipping in Janus blue and immediate evaluation, and for (3) and (4) by dipping in Cresol red followed by heating at 120 ºC for 10 min for (3) and (4).

J. Planar Chromatogr. 26, 370-374 (2013). HPTLC of ciprofloxacin in tablets on silica gel with acetone - water - ammonia 30:3:5. Quantification by absorbance measurement at 280 nm. The hRf of ciprofloxacin was 27. Linearity was in the range of 250-600 ng/zone. Recovery was in the range of 96-101 %. Intermediate/interday/intra-day precision was below 2 %.

Food Chem. 187, 460-468 (2015). HPTLC-direct bioautography of bioactive compounds in the extracts of cold-pressed hemp (1), flax (2) and canola (3) seed oil on silica gel with toluene - ethyl acetate - formic acid - water 15:30:5:3 for (2) and toluene - ethyl acetate - acetic acid 80:25:4 for (1) and (3). HPTLC-DPPH scavenging activity was determined by dipping into a methanolic DPPH solution, followed by drying for 90 s in the dark and heating at 60 °C for 30 s. The hRF values of dominant radical scavenging zones were in the range of 75-85 for (1), 70-90 for (2) and 64 and 95-100 or (3). HPTLC-antimicrobial Aliivibrio fischeri assay allowed the determination of major antimicrobial zones at hRF 40-49 and 55-66 or (1), 23, 45 and 60 for (3) and 95 for (2). Additional effect-directed analyses employing acetylcholinesterase (AChE) assay, planar yeast estrogen (pYES) bioassay and Bacillus subtilis bioassay as well as subsequent HPTLC-ESI-MS allowed targeted characterization of bioactive compounds.
