Location of the taxoids under UV 254 nm. Visualization with Krowitsky reagent (0.5 % cerium(IV) sulfate + 1 % phosphomolybdic acid in 10 % sulfuric acid). Quantitation by densitometry.

Encyclopedia of Chromatography Third Edition 1, 950-953 (2009). The author describes the standard guides of the ASTM designations for forensic writing ink comparison and identification using TLC. Recent advances such as software for visual comparison of chromatograms are included. In addition, new applications of TLC in the field of forensic ink analysis and comparison with spectrometric and chromatographic methods are also described.

Technol., 1991; 453], Marcel Dekker, Inc., New York, N.Y. 1991, 310 pp. Containing chapters on instrumental TLC methods for food quality assurance.

J. Planar Chromatogr. 29, 88-98 (2016). Literature review (1994-2015) of the use of surfactants as mobile phase modifiers for the analysis of organic and inorganic compounds by TLC. The review showed that individual surfactants (cationic, anionic and non-ionic) as well as mixed surfactants (ionic and non-ionic) have been routinely used.

Anal. Chim. Acta 624 (1), 1-15 (2008). Aminoglycosides and macrolides are important antibiotics for veterinary medicine and are widely used in the treatment of bacterial disease, and as feed additives for growth promotion. As a result the European commission set strict criteria for monitoring residues and requires testing for low levels of aminoglycosides and macrolides in foods. Therefore the development of fast, reliable, and sensitive methods for the extraction and subsequent analysis of these antibiotics is of great interest. The review discusses analytical methods for both extraction and determination of antibiotics in various food matrices focusing on the last 10 years. Extraction and clean-up methods such as deproteinization and solid-phase extraction are described, and various screening methods including TLC, EI, CE, microbiological assays, and LC combined with MS are reviewed.

Anal. Chim. Acta 690 (2), 148-161 (2011). Chromatographic fingerprinting has been generally accepted as analytical method for the quality control of herbal medicines. This review describes the evolution of the regulations and guidelines on the quality control of herbal medicines, and reviews the established analytical techniques in TLC, HPLC, UHPLC, hydrophilic interaction chromatography, and GC. Emphasis is put on the most recent developments, such as miniaturized techniques, new stationary phases, analysis at high temperatures and multi-dimensional chromatography. The new chemometric data handling techniques are discussed.

J. Ethnopharmacol. 158, 454-457 (2014). The authors described how the European Pharmacopoeia provides a legal and scientific reference for the quality control of medicines. The document highlighted HPTLC as a tool for the screening of herbal drugs containing certain contaminants, such as aristolochic acids._x000D_

J. Liq. Chromatogr. Relat. Technol. 39, 549-557 (2016). Review of the use of TLC and HPTLC for the analysis of inks in forensic applications, including sample preparation, layers, sample application, detection, documentation and results interpretation. The author also described the application of TLC in food dye analysis as well as future trends in the field.
