J. Agric. Food. Chem. 38, 1417-1422 (1990). TLC of 3-phenoxybenzaldehyde and 11 metabolites on silica with ethyl acetate - formic acid - water 35:2:2, hexane - toluene - acetic acid 3:15:2, toluene - ether - acetic acid 75:25:1. Detection by autoradiography. Quantification after methylation using HPLC.

J. Agric. Food Chem. 46, 3623 - 3629 (1998). HPTLC of ANOT (3-amino-5-nitro-o-toluamide) and primary metabolites on silica gel with chloroform - ethyl acetate - methanol 5:5:1. Detection under UV 366 nm and by exposure to nitrous acid vapors. Finally the plate was sprayed with a Bratton-Marshal solution (0.4% naphthylethylenediamine dihydrochloride in methanol).

J. AOAC Int. 90, 857-863 (2007). TLC of azadirachtin on silica gel with dichloromethane - ethanol 20:1. Detection by spraying with acidified vanillin reagent (3 g vanillin in 10 mL ethanol with 1.5 mL concentrated sulfuric acid) followed by heating at 110 °C for 3 min. Quantitation by densitometry.

CBS 114, 13-15 (2015). To test the new HTpSPE–TOFMS screening, TLC of a pesticide mixture (acetamiprid, azoxystrobin, chlorpyrifos, fenarimol, mepanipyrim, penconazole, pirimicarb) in several plant matrices (cucumber, tomato, grape, apple extracts) on amino layer pre-treated by dipping in 2 % formic acid solution in acetonitrile and drying for 10 min. Development with 10 mL acetonitrile, migration distance 75 mm, drying 5 min; second development in the backwards direction with 10 mL acetone, migration distance 45 mm, drying 3 min. Detection under UV 254 nm, UV 366 nm and white light. For HTpSPE and μL-flow injection analysis–TOFMS the target analyte zone was eluted with the TLC–MS Interface into autosampler vials with acetonitrile – 10 mM ammonium formate 1:1, flow rate 0.2 mL/min, Elution time was 60 s. An HPLC system was coupled via a PEEK capillary and a nano-electrospray ionization interface to a TOFMS without an analytical column. The mean recovery for a pesticide mixture spiked into fruit and vegetable extracts was between 86 % and 116 % with %RSDs of 1.5–10 % (n = 5).

Acta Veterinaria 31, 189-192 (1983). TLC of T-2 toxin, diacetoxscirpenol on silica with Chloroform - ethanol 8:2. Detection by UV 365 nm.

J. Agric. Food Chem. 35, 384-387 (1987). TLC separation of 2 fluvalerate diastereomers (SR, RS and SS, OR) on silica developed 6 times with hexane - ether 20:1. Also two-dimensional TLC.

J. Planar Chromatogr. 3, 6-9 (1990). HPTLC separation of 24 pesticides with the AMD-technique. Two 20-step elution gradients based on dichloromethane and on tert butyl methyl ether were tested. Using HPTLC silica gel layers of 100 µm instead of 200 µm and reducing the running distance increments from 3 mm to 1 mm, both sensitivity and speed of the procedure were increased. Scanning by adsorbance at 200, 220, 240, 260, 280 and 300 nm (multiwavelength).

International Journal of Pharmacognosy 31, 68-76 (1993). TLC of 153 crude plant extracts on silica with petrol ether - ethyl acetate 1:1 for chloroform extracts and with chloroform - methanol - water 65:35:5 for methanol and water extracts. TLC were run in duplicate. One plate was stained with Godin reagent and the other used for direct bioautography with Cladosporium cucumerinum. Activity against Candida albicans was assessed on TLC plates in an agar overlay assay.
