TLC of flumequine (9-fluoro-6,7-dihydro-5-methyl-1-oxo-1H,5H-benzo[ij]quinolizine-2-carboxylic acid) on silica gel in a sandwich chamber with dichloromethane - methanol - 2-propanol - 25 % aqueous ammonia 3:3:5:2. The plates were developed to the top and then continuously for 1 h. Bioautography with nutrient medium and Bacillus subtilis spore suspension. After incubation the plates were sprayed with MTT-solution.

J. Planar Chromatogr. 25, 388-393 (2012). HPTLC of alternariol (1), alternariol monomethyl ether (2), altenuene (3), L-tenuazonic acid (4) in Alternaria alternata strains isolated from foodstuffs on silica gel pre-coated with oxalic acid in methanol with toluene - ethyl acetate - formic acid 6:3:1. Quantitative determination by absorbance measurement at 254 nm. The hRf values of compounds (1) to (4) were 25, 36, 49 and 30, respectively. The %RSD of repeatability were 7–19. Limit of detection for compounds (1) to (3) was 0.3 mg/kg and limit of quantification for (1) to (4) was 5.0 mg/kg in rice cultures with Alternaria alternata mycelium.

J.A.O.A.C. 68, 136-137 (1985). Estimation of aflatoxins B1, B2, G1, G2 on silica with 1) chloroform - acetone 9:1 and 2) ether - methanol - water 96:3:1 in unsaturated tanks. Detection by UV and comparison with standards.

J. Chromatogr. 333, 69-81 (1985). Study on the influence of temperature gradient for different chromatographic systems using the tank developing configuration. Illustration of the method by chromatography of dansyl amino acids and aflatoxins. The enantiomers of the dansyl amino acids could be separated by 2-D-RP TLC with partial separation, then after spraying with Cu complex of N,N-di-n-propyl-L-alanine by separation in a temperature gradient. Aflatoxins B1, B2, G1, G2 were separated on silica with a temperature gradient of 20/min. over 150-180 min.
