Plenary lectures of the 32nd International Congress on Medicinal Plant Research, Antwerp, July 23.-28., 1984. Wissenschaftliche Verlagsgesellschaft, Stuttgart 1985. Review on recent progress in isolation techniques for natural products. TLC, HPTLC, PLC and centrifugal TLC of plant phenolics, alkaloids, essential oil constituents and saponins and related terpenoid glycosides. Numerous separation conditions and critical observations are reported.

TrAC 29, 209-224 (2010). The dangerous effects of cocaine on living organisms and current problems associated with its wide use and availability have led to the development of various analytical procedures. This review discusses analytical methods proposed during the past ten years for the verification of cocaine and its metabolites in biological samples. Challenges regarding sample preparation and extraction techniques are described. Different approaches using thin-layer chromatography are discussed, and especially the possibility of simultaneous determination of parent, metabolite and interfering drugs in urine samples, as well as the identification of markers for combined consumption of cocaine and alcohol.

Trends in Chromatography 6, 1-10 (2010). Review on TLC, HPTLC and other chromatographic methods for the analys of selected metabolite classes such as neutral and polar lipids, amino acids, carbohydrates, carboxylic acids, lipophilic pigments, and purine bases in estivating pulmonate snails.

Food Res. Int. 65, 13-19 (2014). Review of the challenges and limitations in the analysis of polyphenol-protein interactions. The author described some properties of the HPTLC, such as the level of resolution that can be obtained with 2D-HPTLC and the coupling with mass spectrometry, that make this tool a promising alternative for the analysis of protein-phenol adducts.

J. AOAC. Int. 99, 323-331 (2016). This review discusses the most important advances in planar chromatography published between November 1, 2013 and November 1, 2015. Included are an introduction to the current status of the field; student experiments, books, and reviews; chromatographic systems, including stationary phases, mobile phases; apparatus and techniques for sample preparation, TLC procedures, detection and identification of TLC zones and quantitative analysis.

Phytochemistry. 130, 22-46 (2016). The review describes 141 steroidal saponins and sapogenins from the genus Agave reported in the literature from 1970 to 2015. It is a comprehensive review of structures, methods of chemical profiling, including the application of TLC and 2D-TLC for the analysis of saponins and sapogenins, and HPTLC for the determination of hecogenin.

J. Chromatogr. A 1520, 9-22 (2017). A review focused on application of TLC as simple, rapid, popular and inexpensive method for lipophilicity assessment. Discussion of the principles and methodology of quantitative structure retention relationship (QSRR) employed for lipophilicity prediction from retention data. Comparison of traditional and unconventional TLC systems applied for lipophilicity assessment. Overview of the applications of TLC retention constants and use of bioautography as a TLC method complementary in quantitative structure activity relationship (QSAR) studies. Discussion of the advantages and limitations of the method, and application of less common planar chromatography modes for drug discovery process.

J. AOAC Int. 101/5, 1285-1294 (2018). Review of the most important recent studies on antioxidants in foods and beverages, food ingredients, and dietary supplements by effect-directed analysis using TLC with DPPH* (2,2′-diphenyl-1-picrylhydrazyl radical), ABTS*+ (2,2′-azinobis(3-ethylbenzothiaazoline)-6-sulfonic acid radical cation), and β-carotene direct bioautography. Including discussion of the determination of total antioxidant activity by UV/VIS spectrometry combined offline with TLC, mostly for identification and quantification of phenolic compounds; and a dot-blot assay on TLC plate without development, for total antioxidant activity, as alternative with possible advantages compared with spectrometry.
