J. Agric. Food Chem. 39, 412-417 (1991). Analytical and preparative TLC on silica with 7 solvent systems (e.g. dichloromethane - ether 1:1), visualization by autoradiography or by UV; quantification after scraping by liquid scintillation. Also two-dimensional TLC.

(Chinese) J. Chinese Trad. and Herb. drugs 36 (1), 132-137 (2005). A review with 22 references on TLC-bioautography, including the screening of natural compounds with antibacterial and/or antifungal activity, cholinesterase inhibitors, free radical eliminators, and antioxidants. Discussion of the advantages of the technique compared to other related techniques.

J. Chromatogr. Sci. 48 (1), 26-28 (2010). HPTLC of cefuroxime axetil and ornidazole in combined tablet dosage form on silica gel with toluene - n-butanol - triethylamine 17:4:1. The hRf value of ornidazole was 51 and of cefuroxime axetil 67. Quantification by densitometry at 285 nm. Linearity was between 100 and 500 ng/band for both cefuroxime axetil and ornidazole. The method was used for the assay of the compounds in pharmaceutical formulations. The content of cefuroxime axetil was 102.4 % and of ornidazole 101.0 %.

Rapid conversion of the herbicide to ten thytoxic metabolites in a resistant plant, sugarcane. J. Agric. Food Chem. 33, 1070-1075 (1985). TLC and HPTLC separation of isouran and metabolites on silica or RP-8 plates with ether - acetone - chloroform - methanol 9:1, chloroform - methanol - pyridine - acetic acid 15:3:1:1 and methanol - water 7:3. Detection by autoradiography. Comparison with standards.

Arzneim.-Forsch./Drug Res. 41, 392-398 (1991). TLC of nimodipine ((±)3-isopropyl 5-(2-methoxyethyl)1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-pyridine-3,5-dicarboxylate) and metabolites on silica with chloroform - methanol - water - acetic acid 65:28:4:4; 2D TLC using toluene - acetone - acetic acid 70:25:5 and toluene - acetone 1:1. Detection by autoradiography and scintillation.

J. Planar Chromatogr. 17, 464-467 (2004). Displacement chromatography (DC) has been widely used to separate metabolites with similar chemical characteristics. DC works with highly overloaded sample sizes, which are normal for samples not subjected to clean-up. DC successfully handels samples which contain high concentrations of salts and/or proteins, and results in consecutive steps of displaced compounds rather than Gaussian curves. Planar displacement chromatography (DTLC) is suitable for seeking new metabolites in excreted body fluids. Transfer of the radiolabeled methyl group can easily be proven using spacer-displacement planar chromatography. Displacement TLC of L-deprenyl and 14C-L-deprenyl on silica gel with chloroform - triethanolamine 19:1. Detection by X-ray film with an exposure time of 120 h.

Chromatographia 70 (7-8), 1277-1282 (2009). HPTLC of preservatives on three stationary phases of different polarity: RP-18, RP-18W and cyano phase, with methanol – water mixtures in different volume proportions. The resulting RM values showed a linear decrease with increasing methanol concentration of the mobile phase (determination coefficients for all stationary phases were >0.98). The retention behavior of the preservatives on RP phase is in good agreement with their polarity. Principal component analysis showed that for all three stationary phases the same lipophilic interactions take place.

J. Agric. Food Chem. 33, 988-993 (1985). One- or two- dimensional TLC of fenvalarate ((1, cyano (3-phenoxyphenyl) -methyl) 4-chloro-alpha -(1-methylethyl) benzene acetate) and metabolites on silica using hexane - acetone - acetic acid 25:25:1 and toluene - ether - acetic - acid 75:25:1; visualization via autoradiography.
