Gesundheitshilfe Dritte Welt - German Pharma Health Fund e.V., 1994, 108 p. Description of simple and technically undemanding TLC methods for the identification of some compounds from the Essential Drug List, (amoxicillin, ampicillin, benzylpenicillin, chloroquine, various tetracyclines), corticosteroids (dexamethasone, betamethasone, prednisolone, hydrocortisone, hydrocortisone acetate), acetylsalicylic acid, paracetamol, ibuprofen, metamizole, albendazole, and mebendazole. TLC on silica or cellulose with mobile phases as simple and non-toxic as possible. Detection under UV or with platinate solution, Dragendorff's reagent, iodine vapor, ethanolic ninhydrin solution etc.

Trends Anal. Chem. 69, 114-122 (2015). The review discusses methods for the identification of bulk drugs and the active ingredients in formulations. The paper describes a general scheme for the profiling of related organic impurities in drugs involving the use of chromatographic techniques, including TLC.

A book on the basic, techniques and application in pharmaceutical analysis of modern chromatography, including chapters on TLC.

Chin. J. Anal. Lab. (Fenxi Shiyanshi) 19 (2), 91-108 (2000). A review with 879 references, involving TLC method (188 references) from Nov. 1997 to Oct. 1999 for the analysis of more than 200 medicinal herbs or components.

J. Chromatogr. A 1218 (19), 2722-2731 (2011). Review on the features of TLC in the different areas of pharmaceutical analysis, like in-process and intermediate control, illustrated by impurity testing of active ingredients and final products, as well as its application in pharmaceutical research and development. Based on examples reported in the last five years it is shown that TLC is still a very popular and frequently used analytical method in the pharmaceutical industry, although there is a tendency in current pharmacopoeias for favouring HPLC.

Anal. Chim. Acta 632 (2), 168-180 (2009). Ochratoxins and aflatoxins are the most significant mycotoxins and there has been a broad range of research. However, it is impossible to use one standard technique for the analysis because of the various structures of mycotoxins. The review discusses existing analytical and detection techniques, such as 1) sample pre-treatment methods like liquid-liquid extraction, supercritical fluid extraction, or solid phase extraction; 2) separation methods such as TLC, HPLC, GC, and CE and 3) other methods such as ELISA. The practical requirements for high-sensitivity analysis and the need for a specialist laboratory setting create challenges for routine analysis. There are a number of methods used, but there is no single technique that stands out above the rest, although HPLC-MS is popular. Discussion of further currents trends, advantages and disadvantages and future prospects of these methods.

J. AOAC Int. 98, 850-856 (2015). Review of the development of planar chromatography-direct bioautography methodology, with special emphasis on its use as a biomonitoring system. HPTLC of cis-spiroether (1), trans-spiroether (2), alpha-bisabolol (3), bisabolol oxides (4) and the fluorescent coumarin derivatives herniarin (5), and umbelliferone (6) in chamomile extracts on silica gel with chloroform - acetone 99:1. Detection by dipping into vanillin–sulfuric acid reagent (40 mg vanillin, 10 mL ethanol and 200 mL concentrated sulfuric acid) followed by heating at 110 °C for 5 min. Bioassays were performed by the direct bioautographic system using a Gram-negative test bacteria (Xanthomanas euvesicatoria), the luminescence gene-tagged Arabidopsis pathogen (Pseudomonas syringae pv. maculicola) and the luminescent marine bacterium (Aliivibrio fischeri) as well as a Gram-positive soil bacterium (Bacillus subtilis).

Trends Anal. Chem. 85, 75-84 (2016). This review describes different approaches for characterization of fossil resins (including amber and all their various types), including chromatographic methods and the application of TLC for separation and purification of compounds and its coupling with mass spectrometry. Fossil resins are often adulterated with modern resins and some rare and precious fossil resin specimens are imitated by more abundant, cheaper fossil specimen (for example succinite – Baltic amber is often imitated by copal).
