J. of Chromatogr. A 1218 (19), 2676-2683 (2011). A review on bioautography on TLC plates as an important means of detecting the biological activity of a sample. The technique requires only small amounts of sample, is ideal for the investigation of plant constituents which often occur as complex mixtures, and can be used for the target-directed isolation of these constituents. In contrast to HPLC, many samples can be run at the same time on TLC, and organic solvents, which cause inactivation of enzymes or death of living organisms, can be completely removed before biological detection. Many bioassays are compatible with TLC and antimicrobial, radical scavenging, antioxidant activities and enzyme inhibition tests can be applied.

The usage of double bonds photoisomerization for identification of organic compounds by thin-layer chromatography. J. Liquid Chromatogr. 8, 1239-1246 (1985). Presentation of a TLC technique combining chromatographic separation and identification of organic compounds containing double-bonds. Method based on different chromatographic mobility of Z- and E- isomers, and applied for the identification of aromatic azo- and azoxycompounds, stilbene derivatives and unsaturated acids.

Anal. Chim. Acta 192, 309-313 (1987). Description of 3 fluorescent derivatization reagents for compounds having hydroxyl and/or amino groups, which were stable at room temperature and condense stechiometrically with alcohols, amines and amino acids in the presence of alkali to give strongly fluorescent derivatives. Pre-chromatographic derivatization followed by TLC and HPLC.

J. Chromatogr. 504, 456-463 (1990). TLC of title compounds on cellulose or silica with one of the following solvents; 1) 2-methylpropan-2-ol - butanone - propanone - methanol - water - NH3 40:20:20:1:14:5, 2) butanol - propanone - acetic acid - water 35:35:10:20. Detection: spraying with 2,4-dinitrophenylpyridium chloride in methanol 200 mg/L for cellulose and 100 mg/L for silica - placing the plate in sealed glass tank with alkaline atmosphere for 15 min, keeping plate in the dark for 24 h before recording the fluorescence.

Analyst 119, 415-516 (1994). Presentation of a spray reagent for the detection of carbamate insecticide carbaryl, consisting of 1% ammonium cerium (IV) nitrate in 20%(v/v) hydrochloric acid, which reacts exclusively with the hydrolysis product of carbaryl, 1-naphthol, and forms a violet complex. Sensitivity, about 100 ng.

J. Chromatogr. A 750, 403-407 (1996). TLC of organophosphorus insecticides, carbamates and pentachlorophenol, etc. on silica with tetrahydrofuran - hexane 7:25, and hexane - ethyl acetate 3:2. Detection by using biological or biochemical tests. Investigation of the relationship between the signal of the inhibition of cholinesterase and the concentration of the inhibitor using a constant enzyme concentration and a constant incubation time. Quantification by densitometry or videodensitometry.

Anal. Chim. Acta 488, 203-209 (2003). Dansylation of aromatic carboxyl compounds (i.e. aspirin), aromatic primary amines, and aliphatic carboxyl compounds in 1 M Na2CO3 buffer at pH 11. TLC on silica gel of fluorescent labeled analytes using methylene chloride, ethyl acetate, acetone, or desired mixture of the solvents. Methylene chloride was superior to ethyl acetate or acetone. Fluorescent analytes were observed under UV lamp. Limits of detection for dansylated carboxyl compounds was 1-5 µg.
