Chromatographic Science Series, No. 95, CRC Press - Taylor and Francis Group, Boca Raton, 2006, 424 pp. Designed as a practical, comprehensive source of information on the field of classical preparative layer chromatography (PLC), the monograph is a valuable and important supplement to the existing vast chromatographic literature, demonstrating the potential of PLC for separation and isolation of pure compounds, even from very complex mixtures. The book is organized on two parts, the first of which covers the theory and up-to-date procedures of PLC (chapters 1 through 8), while the second (chapters 9 through 16) includes applications to a selection of the most important classes and sample types. Section I: Introduction; Adsorption Planar Chromatography in the Nonlinear Range: Selected Drawbacks and Selected Guidelines; Sorbents and Precoated Layers in PLC; Selection and Optimization of the Moblile Phase for PLC; Sample Application and Chromatogram Development; Application of Horizontal Chambers; Location of Separated Zones by Use of Visualization Reagents, UV Absorbance on Layers Containing a Fluorescent Indicator, and Densitometry; Additional Detection Methods and Removal of Zones from the Layer. Section II: Medical Applications of PLC; PLC of Hydrophilic Vitamins; Preparative Layer Chromatography of Natural Mixtures; The Use of PLC for the Separation of Natural Pigments; Application of PLC to Inorganics and Organometallics; PLC in a Cleanup and Ground Fractionation of Geochemical Samples; The Use of PLC for Isolation and Identification of Unknown Compounds from the Frankincense Resin (Olibanum): Strategies for Finding Marker Substances.

J. Liq. Chromatogr. Relat. Technol. 35, 1497-1516 (2012). The authors reviewed stationary phases, solvent systems, and detection reagents developed for the analysis of amino acids. Polar and non-polar layers as well as impregnated layers mainly with metal ions and also with chiral agents were described for the separation and identification of amino acids. On the other hand, over fifty mobile phases were reviewed for the analysis of amino acids, with a recent tendency in the use of surfactants as less toxic reagents. Methodologies for the separation of amino acid enantiomers, such as the use of beta-cyclodextrin as chiral mobile phase as well as derivatization methods such as iodine azide reaction to enhance sensitivity in detection were also described. TLC has a privileged position due to its simplicity, convenience, and cost-effectiveness for separation of amino acids.

Review on chromatographic methods for synthetic food dyes, including the following techniques: TLC, HPTLC, traditional column chromatography, HPLC, ion-pair chromatography, RP HPLC, and high performance ion chromatography, demonstrated by using examples in different conditions for each technique.

J. AOAC Int. 93, 754-764 (2010). The review describes analytical methods for drug substances, formulations, and clinical samples analyzed and validated by HPTLC during the period 1996-2009. Procedures, materials, and instrumentation for the different steps in the chromatographic procedure and validation of results are given; application to bulk drugs, formulations, stability studies, biological samples (e.g., urine and plasma), and hydrophobicity studies; and prospects for the future use of HPTLC for drug analysis are described. The sections cover the experimental procedures (sample preparation, stationary phases, mobile phases, application of standards and samples, chromatogram development, detection, documentation of chromatograms, densitometric quantitative analysis), determination of hydrophobicity, confirmation of zone identity, method validation, chiral separations, micropreparative layer chromatography, applications of HPTLC-densitometry, and future prospects for HPTLC in drug analysis. 155 references are reviewed.
