J.A.O.A.C. 71, 872-874 (1988). TLC of pesticides (DDT complex, HCH isomers, heptachlor and epoxide, aldrin and dieldrin, HCB) on alumina with heptane. Visualization by spraying with AgNO3 and followed by UV exposure.

J. Pharm. Biomed. Anal. 8, 1087-1090 (1990). TLC of hippuric acids on silica with chloroform - acetone - glacial acetic acid 40:10:5, of methylhippuric acids with toluene - methanol - nitromethane - acetic acid 5:8:2:2, for chlorohippuric acids with nitrobenzene - ethyl acetate - glacial acetic acid 45:8:5. Quantification by densitometry at 495 nm. TLC of mandelic and phenylglycilic acid on Silufor™ with toluene - acetonitrile - glacial acetic acid - acetone 30:8:4:1. Detection of aromatic acids by spraying with 0.5% tetrazolium blue in methanol - NH3 1:1, exposure to UV 366 nm for 75 min, afterwards quantification by densitometry at 475-540 nm. Comparison of the results with those obtained by GC. The TLC method allows a rapid simultaneous screening of many samples on the same plate.

Detection under UV 366 nm and by spraying with 1-naphthol reagent (adding of a 15% ethanolic solution of 1-naphthol to a mixture of 40.5 mL of ethanol, 4 mL water, 6.5 mL sulfuric acid) and by heating at 100 °C for 5 min.

J. Planar Chromatogr. 8, 388 - 392 (1995). HPTLC of MDA.HCl, MDMA.HCl, MDE.HCl, BDB.HCl, MBDB.HCl, LSD, and atropine on silica with dichloromethane - methanol 200:3 in the presence of NH3 in a separate 10 mL glass vessel for LSD, ethyl acetate - acetone - methanol - 25% NH3 50:50:20:1 for MBDB, acetone - ethanol - 25% NH3 90:7:3 for atropine. Identification by in situ FTIR measurement.

J. AOAC Int. 79, 1330-1335 (1996). TLC of aflatoxins B1, B2, G1, G2 on silica with chloroform - acetone 22:3. UV detection at 360 nm. The use of the TLC conditions of the CB (Contaminants Branch) method gave better results than BF (Best Food) and CB-RCS-Mod (modified CB method - Rapid Modification of the Cottonseed Method): less fluorescent interferences, better solvent efficiency, lower detection levels.

J. Planar Chromatogr. 18, 212-216 (2005). Retention factors on RP-18 layers corresponding to zero percent organic modifier in the aqueous mobile phase were determined for five mobile phase mixtures: methanol - water, acetone - water, acetonitrile - water, 2-propanol - water, and tetrahydrofuran - water and relationships between the retention factors obtained with different organic mobile phase modifiers were examined. A variety of partition coefficients were calculated by use of different software products and the correlation between these partition coefficients and chromatographically obtained lipophilicity was analyzed. On the basis of of correlations between retention factors and the partition coefficient log P, RP-18 with methanol - water as mobile phase was selected as the best RP-HPTLC system for determination of the octanol/water partition coefficient and thus the lipophilicity of the molecules. Visualization under UV light at 254 nm.

Food Chem. 91, 757-764 (2005). HPTLC of dihydrosanguinarine (1), after its conversion to sanguinarine (2) as an index of argemone oil adulteration in edible mustard oil, on silica gel with hexane – acetone – methanol 16:3:1. The plate was irradiated under long wave UV light for 15 min to oxidize (1) to (2). Quantitative determination by absorbance measurement at 366 nm. The hRf values for (1) and (2) were 82 and 36, respectively. Linearity was between 5 and 300 ng/zone for (2). The limit of detection and quantification was 1 and 3 ng/zone. Recovery was between 79 and 82 %.
