J. Agric. Food. Chem. 38, 1004-1006 (1990). TLC of aflatoxins B1, B2, G1, G2 on silica with ether and then chloroform - acetone 22:3 or with chloroform - ether - acetic acid 17:3:1; zearalenone and tricothecenes on silica with hexane - ether - acetic acid 70:30:2, visualization of zearalenon under UV (254 nm and 366 nm); subsequent development with hexane - ethyl acetate 1:3, spraying with an ethanolic solution of AlCl3 (20%) and heating at 110°C for 10 min. Deoxynivalenol appeared as blue fluorescent spot under UV 366 nm. Finally the plate was sprayed with sulfuric acid - methanol 1:4 and heated at 130 °C for 10 min. T-2 toxin and diacetoxyscirpenol appear as greenish-blue and dark green fluorescent spots.

J. Planar Chromatogr. 4, 373-378 (1991). TLC of amphetamine and 77 analogs on silica and RP-18 silica with toluene - acetone 94% ethanol - 25% NH3 45:45:7:3 and methanol - water 37% hydrochloric acid 50:50:1 resp. Detection by spraying with a filtered 0.5% aqueous solution of FBK, dried briefly with a hot-air blower, sprayed lightly with 0.5M sodium hydroxide solution, dried, and sprayed again with FBK. Detection limit 0.1 µg. All amphetamine derivatives could be readily classified, according to the color of the spots, into primary and secondary amines. The combined use of the chromatographic systems and the color reaction generally enabled differentiation of amphetamine derivatives from other drugs and in most cases from each other.

HPTLC of visaltricin (3-(1-methyl-4-(3-methyl-2-butenyl)imidazol-5-yl)-2-propenoic acid) with benzene - acetone 12:7; chloroform - methanol 9:1; chloroform - methanol 90:10:1. Detection by spraying with p-anisaldehyde solution and heating at 110 °C for 5 min.

Appl. Environm. Microbiol. 59, 2864-2867 (1993). TLC of fumonisin B1 on silica 60 with a) 1-butanol - acetic acid - water 2:1:10 and b) chloroform - methanol - water - acetic acid 55:36:8:1. Densitometry after derivatization with p-anisaldehyde at 600 nm.

J. AOAC Int. 79, 1263-1268 (1996). TLC separation of erythromycin, tylosin and 11 other drugs (oxytetracycline, chlortetracycline-HCl, furazolidone, nitrofurazone, nitrofurantoin, sulfathiazole, sulfadiazine, sulfamerazine, amprolium, olaquindox, ronidazole) on silica with chloroform - methanol 10:1 with traces of NH3. Detection under UV 254 and 366 nm; also spraying with 10 % sulfuric acid in ethanol and heating at 120°C for 3 min.

J. Planar Chromatogr. 18, 397-399 (2005). TLC of chloral hydrate, diazepam, phenobarbitone, saccharin, and anthranilic acid on silica gel in a presaturated chamber with n-hexane - acetone - methanol 16:6:1. Detection by spraying with 2 % sodium hydroxide solution, followed by spraying with 0.5 % orcinol solution and heating in an oven at 90 °C for 10 min. Evaluation under UV at 366 nm.

J. Planar Chromatogr. 20, 69-71 (2007). TLC of mycotoxins (aflatoxin B1, B2, G1, ochratoxin A, sterigmatocystin, chaetomins, roquefortine C, penicillic acid, trichothecenes) on silica gel, prewashed with methanol, with chloroform - xylene - acetone 6:3:1. Detection under UV and by spraying with 0.5 % anisaldehyde in sulfuric acid followed by heating at 110 °C for 10 min.

J. Planar Chromatogr. 22, 59-63 (2009). HPTLC of paraquat, diquat, difenzoquat, mepiquat, and chloromequat on LiChrospher silica gel with 1-propanol - methanol - 2.5 M aqueous sodium chloride 1:1:3. Detection by immersion for 2 s in a solution of 50 mg sodium tetraphenyl borate in 50 mL of water containing 50 µL concentrated hydrochloric acid. The wet plate was illuminated for 5 min with UV light at 254 nm which resulted in the formation of fluorescing spots corresponding to mepiquat, chloromequat, and difenzoquat. Immediately after illuminating at 254 nm all spots were illuminated for 10 min with UV light at 365 nm, which converted all compounds into fluorescent derivatives. Then the dry plate was dipped into ethylene glycol - methanol 1:1 for 2 s, which enhanced the fluorescence by a factor of two. Detection by fluorescence measurement and averaged densitograms were obtained in the emission wavelength range from 440 to 480 nm.
