J. Chromatogr. A 815, 3-20 (1998). A review with 136 references on the status of TLC of mycotoxins in various sample matrices, stressing on the merits of TLC in qualitative and quantitative determination of the toxins. General comparison between different TLC methods, TLC with HPLC, ELISA and GC, etc.

JAOAC Int. 84, 1219-1231 (2001). Compilation of the role of planar chromatography (PC) in medicinal and aromatic plant (MAP) research and development, and demonstration of the importance of the technique, after extraction, in the analysis of MAP (identification and quantitative determination of the separated compound/s), in the purification and isolation process, and in different types of screening procedure. Special attention is paid to analytical, micropreparative and preparative forced-flow techniques, for example OPLC and rotation planar chromatography (RPC). Purification and isolation procedures are shown in flowcharts. Some applications, relating to different classes of substance, are presented to demonstrate the versatility of various planar chromatographic techniques.

Anal. Chem. 72, 9R-25R (2000). Selective review of the literature of TLC and HPTLC in Chemical Abstracts from November 1, 1997 to November 1, 1999. The literature search was augmented by consulting Analytical Abstracts, Chemical Titles and Current Contents, and the following journals were searched directly: J. Chrom. (parts A and B and the bibliography issues), J. Chrom. Science, Chromatographia, Anal. Chem., J. Liq. Chrom. & Rel. Technol., J. AOAC Int., J. Planar Chromatogr. – Modern TLC and Acta Chrom. The different chapters are: history, student experiments, books and reviews; theory and fundamental studies; chromatographic systems (stationary and mobile phases); apparatus and techniques; detection and identification of separated zones; quantitative analysis; preparative layer chromatography, thin-layer radio-chromatography and applications of TLC/HPTLC. 415 references from the last 2 years.

Encyclopedia of Chromatography Third Edition 1, 234-237 (2009). The author describes the combination of TLC or HPTLC with bioluminiscence detection for the effect-directed analysis (EDA) of bioactive zones on the layer. Specifically, bioactivity screening of complex mixtures by separation on HPTLC plates followed by dipping into a solution of the bioluminescent bacteria Vibrio fischeri is described.

Anal. Chem. 62, 371R-381R (1990). A review with 487 references on TLC and paper chromatography, including theory, fundamental studies, chromatographic systems, detection and identification of separated zones, quantitative methods, preparative TLC and radio TLC, etc.

J. Planar Chromatogr. 21, 315-323 (2008). The role of the mobile phase in controlling selectivity for adsorption chromatography - with either thin-layer plates or columns - is reviewed and expanded. The use of different solvent mixtures of varying selectivity in normal-phase chromatography is now on a firm theoretical and practical basis. The choice of a more polar component (B-solvent) of a binary solvent mixture (A/B) largely determines relative retention and resolution. Maximum differences in selectivity are achieved by the use of two mobile phases where the B-solvent is either very polar (requiring a lower % B for desirable values of k) or relatively nonpolar (requiring a higher % B).
