J. Liq. Chromatogr. Relat. Technol. 31, 1969-1976 (2008). TLC of urethane on spherical silica gel with methyl-t-butyl ether - methanol 7:3. Detection by immersion in a solution of 80 µL cinnamaldehyde in 40 mL acetone with 2.4 mL phosphoric acid followed by heating in an oven at 130 °C for 10 min. The fluorescence can be enhanced by the factor of 2 if the plate is dipped for 4 s into a solution of 10 % polyethylene glycol 600 in methanol. Quantitative determination by absorbance measurement in the range of 445 to 460 nm.

Phytochem. Anal. 20, 421-426 (2009). HPTLC of delta-9-tetrahydrocannabinol in the flowertops of Cannabis sativa on silica gel with chloroform with chamber saturation for 20 min. Quantitative determination by absorbance measurement at 206 nm. Derivatization by dipping in Fast Blue B solution for 5 s. The hRf value of delta-9-tetrahydrocannabinol was 47 and selectivity regarding matrix was given. Linearity was given between 50 and 500 ng/zone. The limit of quantification and detection was 50 and 10 ng/zone, respectively. The intra- and inter-day repeatability (%RSD, n = 9) were not higher than 5.0 %. Recovery was 85.8 % for delta-9-tetrahydrocannabinol in decarboxylated Cannabis samples. The method was shown to be comparable within a small degree of error (0.5 %) to results from a validated HPLC method.

J. Planar Chromatogr. 24, 445-446 (2011). TLC of cypermethrin as standard and in ethanolic viscera extracts on silica gel with cyclohexane - toluene 3:2 in a saturated chamber. Detection at UV 254 nm and after spraying with 20 % sodium hydroxide solution followed by 1 % copper(II)acetate solution and 1 % phosphomolybdic acid solution. After 5 min, the plate was sprayed with 0.1 % o-tolidine reagent and intense blue zones due to the quinodial oxidation product of o-tolidine were detected. The hRf value for cypermethrin was 38.

J. Planar Chromatogr. 26, 14-20 (2013). HPTLC of permethrin on silica gel with hexane - diethylether - ethyl acetate 22:2:1. Quantitative determination by absorbance measurement at 227 nm. The hRf values of cis- and trans-permethrin were 72 and 62, respectively. Linearity was in the range of 300-1800 ng/zone. LOD of cis- and trans-permethrin was 1.6 and 2.4 ng/zone, respectively. LOQ was 4.9 and 7.4 ng/zone for cis- and trans-permethrin, respectively. Intermediate precision was below 2 %.

J. Planar Chromatogr. 28, 352-353 (2015). HPTLC of imidacloprid on silica gel with dichloromethane – isopropyl alcohol 1:3. Detection by spraying with cobalt thiocyanate reagent (3 g ammonium thiocyanate and 1 g cobalt(II) chloride in 20 mL distilled water). The hRF value for imidacloprid was 82.

J. Agric. Food Chem. 65, 8773-8778 (2017). HPTLC of aflatoxin B1 on silica gel with chloroform – ethyl acetate 4:1. Quantitative determination by fluorescence measurement at 366/>400 nm.

Chem. Pharm. Bull. 32, 4942-4945 (1984). TLC of 7 mutagenic xanthones on silica. Quantification by densitometry. Investigation of the conditions of the analysis. The relationship between xanthone content and mutagenicity is discussed.

J. Agric. Food Chem. 34, 689-701 (1986). Determination of diacetoxyscirpenol and metabolites on silica with chloroform - methanol 9:1 and chloroform - acetone 3:2. Detection by UV 254 nm and by heating the plates at 130 °C for 5 min after treating with 30 % sulfuric acid in methanol. Additional TLC visualization by treatment with 4-(p-nitrobenzyl) pyridine.
