Springer Verlag, Heidelberg 1986, 139 pages. Review on recent progress in isolation techniques for natural products. PLC, centrifugal TLC, column chromatography, prep. HPLC, counter-current chromatography of various plant constituents. Numerous separation condition. and critical observations are reported.

J. of Chromatogr. A 1218 (19), 2676-2683 (2011). A review on bioautography on TLC plates as an important means of detecting the biological activity of a sample. The technique requires only small amounts of sample, is ideal for the investigation of plant constituents which often occur as complex mixtures, and can be used for the target-directed isolation of these constituents. In contrast to HPLC, many samples can be run at the same time on TLC, and organic solvents, which cause inactivation of enzymes or death of living organisms, can be completely removed before biological detection. Many bioassays are compatible with TLC and antimicrobial, radical scavenging, antioxidant activities and enzyme inhibition tests can be applied.

J. Chromatogr. A 1232, 3-18 (2012). A review on overpressured-layer chromatography (OPLC). OPLC is a separation technique that combines the advantages of conventional TLC/HPTLC with those of HPLC. Use of a special chromatoplate and a pump to increase and optimize the mobile phase flow velocity through an optional development distance in an adsorbent layer by employing the pressurized ultramicro (UM) chamber as a closed adsorbent layer chamber. Description of the versions of OPLC instruments, the character and achievement of off-line and on-line OPLC systems in analytical and preparative use. Demonstration of the unique advantages of planar-layer systems for detection, isolation and identification of new antimicrobials, antineoplastics, biopesticides and other biologically active substances as well as for studying fundamental biochemical reactions and mechanisms by BioArena which was newly developed as a complex bioautographic system.

Food Control. 68, 310-329 (2016). Review of the methodologies to determine the occurrence of aflatoxin M1 (AFM1) and the fate of AFM1 during processing of milk and dairy products, such as yoghurt and cheeses, since 1996 until today. The review describes the application of TLC and HPTLC in raw and pasteurized milk, feta cheese, yoghurt, white cheese, ice cream and butter.

Food Control. 72, 145-152 (2017). The paper discussed five important adulteration events that occured in Taiwan between 2011 and 2015, including a review of analytical methods developed by the Taiwnan Food and Drug Administration to investigate these incidents, including HPTLC methods for the detection of copper chlorophyll, Cu-pyropheophytin A, from slurry green dyes obtained from edible oils. _x000D_

J. Ethnopharmacol. 220, 197-219 (2018). Review of traditional uses, phytochemistry, pharmacology, antimicrobial potential, including the literature published on the application of TLC and HPTLC for taxonomic validity of P. emodi.

Food Chem. 278, 144-162 (2019). Review of methodologies, including TLC, HPTLC and its combination with mass spectrometry for the detection of potential biomarkers for the differentiation among species, varieties and cultivars of different foodstuffs, as well as metabolites as potential biomarkers for food authenticity according to production systems and for the detection of food spoilage and freshness.
