Chromatographic Science Series, Vol. 98, CRC Press, Boca Raton, New York, 2007. XVI + 420 pp.; ISBN 978-0-8493-4369-8. The problem of analysis of enantiomers became acute with the realization that the enantiomers of a drug may have quite different biological activity. TLC for chiral separations is simpler and less expensive than HPLC and enables simultaneous analysis of several samples in a short time. Densitometry and videoscanning enable quantitative analysis with satisfactory accuracy, and - in certain cases - chiral plates can be regenerated. In 15 chapters 24 authors cover all important aspects of the separation and analysis of enantiomers by planar chromatography. In the first and second chapter an overview and general information on chirality is presented; the use of precoated plates, of noncommercial plates, of cellulose- and silica gel-based adsorbents is discussed in the chapters 3 to 5. Chapter 6 summarizes the use of mobile phases containing chiral selectors. Information on the molecular mechanisms and the separation of stable or transient diastereoisomers can be found in chapter 7 and 8, whereas the next chapter is devoted to especially difficult separations using 2D TLC. The next five chapters review applications of TLC in the analysis of enantiomers of important compounds. Extensive literature is cited by the authors.

Planta Med. 75, 711-718 (2009). For many decades, planar chromatography has been used for the analysis of plants, in particular today in its most advanced form of HPTLC. The technique is e. g. used for the identification of medicinal plants and dietary supplements, and for the detection of adulteration and quantitative determination of marker substances. Reliable qualitative and quantitative results can be achieved based on suitable instrumentation and adequate methodological concepts. The manageability of the entire planar chromatographic process has improved. Integration of biological detection systems as well as hyphenation to mass spectroscopy has widened the applicability of planar chromatography as an important analytical technique. The introduction is followed by explanation of HPTLC, use of HPTLC in plant analysis, limitations, applications (identification, detection of adulteration and quantitation), and instrumentation (chromatogram development, documentation, detection and evaluation).

J. Planar Chromatogr. 29, 162-164 (2016). Book review of the 1st edition of "Forced-flow layer chromatography", published in 2015 by Elsevier Science Publishing Co Inc. The book describes the specifics of the technique, from its evolution to the characteristic nuances that complement TLC and HPTLC. The review provides a short introduction of each of the eight chapters, as well as key features of the book, including biological aspects.

The book describes the TLC analysis of ingredients of about 230 plant drugs of worldwide interest grouped into 19 classes. 184 color images document the separation results. The book is a valuable collection for drug analysis.
