J. Agric. Food Chem. 49, 3278-3283 (2001). Fractionation of alkenes by AgNO3-TLC; plates prepared by dipping for 1 min in a mixture of 10% aqueous AgNO3 solution and ethanol 1:1. The plate was then dried in an oven at 70°C for 20 min. TLC of sesquiterpenes (e.g. cyclosativene, longicyclene, a-copaene, b-cubebene, ?-elemene) on silica gel with n-hexane. Visualization under UV 254 nm after spraying with a 0.2% ethanolic solution of 2,7-dichlorofluorescein.

Planta med. 70, 201-204 (2004). Analytical and preparative TLC of dihydrotanshinone, cryptotanshinone, and tanshinone I, IIA on silica gel with dichloromethane and dichloromethane - ethyl acetate 4:1.

Pharmazie 62, 226-230 (2007). TLC of two metabolites of the sesquiterpene lactone parthenin on RP-18 and silica gel with dichloromethane - methanol 19:1. Detection by spraying with vanillin-sulfuric acid followed by heating. Also TLC method for detection of hydroperoxy radical: the developed chromatogram was air dried, sprayed with a freshly prepared spray reagent (50 mL of 1 % ethanolic solution of ferrous ammonium sulfate were mixed with 5 mL of 1 M sulfuric acid, and added to 5 mL ethanolic solution of ammonium thiocyanate). A dark red coloured zone was considered as a positive result. Ascaridol and hydrogen peroxide were used as positive controls.

J. Planar Chromatogr. 30, 121-125 (2017). Overpressured TLC of essential oil components of clove, rosemary, eucalyptus, tea tree, spearmint, thyme, and cinnamon on silica gel with toluene. The conditions in infusion mode were as follows: 50 bar, external pressure; 350 μL, rapid mobile phase flush; 500 μL/min, mobile phase flow rate; 3900 μL, mobile phase; 475 s, development time. The hRF values were 8 for α-terpineol, 12 for borneol, 17 for terpinen-4-ol, 20 for 1,8-cineole, 22 for R(–)-carvone, 31 for trans-cinnamaldehyde, 36 for eugenol and 43 for thymol. Antibacterial and antioxidant activities were also detected by infusion–transfusion OPLC hyphenated with Aliivibrio fischeri assay and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay, respectively.

(Leaves of sage und three-lobed leaves of sage). Deutsche Apotheker Zeitung 130, 169-170, (1990). TLC of a,ß-thujon, cineol, campher, borneol and bornylacetate (leaves of sage), cineol, a,ß-thujon, campher, borneol, bornylacetate, caryophyllen, epoxy-dihydrocaryophyllen (three-lobed leaves of sage) on silica with toluene – ethyl acetate 95:5. Detection by spraying with anisaldehyde – sulfuric acid reagent, heating at 100-105°C for 5 min, observation under day light or UV 365 nm.

J. Liquid Chromatogr. 18, 105-115 (1995). TLC of the title compounds on silica with benzene - isopropyl ether 1:1. Detection under UV 254 nm. Identification of the eluted spots by GC-MS. Quantification by densitometry at 254 nm.

J. Chromatogr. A 1459, 145-151 (2016). Presentation of a novel method for coupling TLC with ion mobility spectrometry (IMS) using laser desorption technique (LD). Sampling of the compounds (explosives like trinitrotoluene, 1,3,5-trinitro-1,3,5-triazacyclohexane, pentaerythritol tetranitrate, 2,4-dinitrotoluene and 3,4-dinitrotoluene; amino acids like alanine, proline and isoleucine, nicotine and diphenylamine mixtures) on the layer surface within less than 80 s after TLC separation by using the LD-IMS technique without the need of any further manipulation or preparation. The TLC plate was moved in desired directions by the motorized micro-positioning stage towards the right position of the fixed laser. TLC-LD-IMS offers an additional separation dimension, allowing separation of overlapping TLC analytes, and reveals possibility for fast and effective analysis of the mixtures due to the scan rate for LD being adjustable.
