J. Agric. Food Chem. 34, 74-78 (1986) TLC of (3H) avermectin B1a on silica, development twice in one direction with ethyl acetate - benzene -2-propanol 10:5:1. Location of radioactive zones by autoradiography, quantification by LSC. For autofluorography, plates were sprayed with 10 % solution of PPO in toluene; they were then air-dried and exposed at 30 °C to X-ray films.

Chinese J. Plant Physiol. (Zhiwu Shenglixue Tongxun) 6, 60-62 (1989). TLC of avenic acid, deoxymugineic acid, mugineic acid, hydroxymugineic acid, and epi-3-hydroxymugineic acid on cellulose with 50% acetone solution containing 0.5% copper sulfate. Detection by UV spectrometry at 366 nm and 255 nm.

J. Planar Chromatogr. 11, 205-210 (1998). Investigation of seven different thin-layer chromatographic systems (i.a. silica gel, silanized silica gel, silanized silica gel/Cu(II) cation, chemically bonded RP-8, chemically bonded RP-18) to determine their usefulness for separation of 19 pairs of the E-Z geometrical isomers of pyrazole, pyrimidine, and purine derivatives with potential cytokinin activity. A variety of binary (aqueous and nonaqueous) mobile phases have been used. The best performance was observed with silica gel as stationary phase and hexane - ethyl acetate 1:9.

J. Planar Chromatogr. 19, 15-20 (2006). TLC and HPTLC of fifteen urea pesticides (monolinuron, chlorotoluron, diuron, isoproturon, linuron, dimefuron, diflubenzuron, teflubenzuron, lufennuron, thifensulfuron methyl, triasulfuron, chlorsulfuron, rimsulfuron, amidosulfuron, tribenuron methyl) on RP18 with methanol - water and mixed organic (acetonitrile - methanol 1:1) - 0.1 % aqueous orthophosphoric acid mobile phases, and on silica gel with benzene - methanol and benzene - ethanol mobile phases. Relationships between Rf values and mobile phase composition were determined.

J. Planar Chromatogr. 22, 333-343 (2009). TLC of brodifacoum, bromadiolone, coumateralyl and impurities on silica gel, alumina, cellulose, and RP-18 with 46 different mobile phases in a twin trough chamber saturated for 30 min. The most selective phases on silica gel were chloroform - ethyl acetate - n-hexane in various ratios, ethyl methylketone- toluene 1:9, and chloroform - toluene 7:3; on alumina the best mobile phase was dichloromethane - n-hexane 3:2. Detection under UV light at 254 nm.

J. Agric. Food Chem. 34, 1057-1060 (1986). Preparative TLC of aziridine derivatives on silica with ethyl acetate - hexane 1:1 or chloroform - methanol 99:1. Detection by viewing under UV 254 nm and by iodine exposure.

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).
