J. Planar Chromatogr. 19, 92-97 (2006). Two-dimensional HPTLC of naringenin, acacetin, flavone, morin, hesperetin, quercetin, narcisin, kaempferol 3,7-dirhamnoside, naringin, rutin, astragalin, quercitrin, kaempferol 3-glyco-7-rhamnoside, naringenin 7-glucoside, ferulic acid, chlorogenic acid, elagic acid, caffeic acid, p-coumaric acid, m-coumaric acid, o-coumaric acid, and gallic acid by connecting diol or silica plates to RP18 plates, with e. g. acetone - water 2:3 or 1:1 in first direction of development and propan-2-ol - ethyl acetate 1:1 or methanol - ethyl acetate 1:9 in second direction of development. Derivatization by use of diphenylboric acid 2-aminoethylester (natural products reagent), followed by PEG 400 reagent; detection under 365 nm.

International Journal of ChemTech Research 1(4), 1122-1128 (2009). TLC on silica gel with toluene - ethyl acetate 3:1. The hRf value of the furanocoumarin psoralen was 47. Densitometric evaluation at 299 nm. The method was linear in the range of 10-100 ng/band. The average recovery was 99.7 %.

CBS 109, 2-4 (2012). Extraction of arabica coffee with 2 to 50 % robusta coffee by accelerated solvent extraction with tBME. A part was saponified with10 % ethanolic KOH solution for 2 h. HPTLC of coffee extracts and standards 16-O-methylcafestol (16-OMC) and 16-OMC esters on silica gel with toluene - ethyl acetate - acetic acid 93:7:1 for 16-OMC esters and with tBME - chloroform 1:1 for 16-OMC. Detection by spraying with vanillin sulfuric acid (1 g in 250 mL ethanol and 2 mL of sulfuric acid, prepared freshly) and heating for 1 min at 80 °C. Quantitative absorption measurement at 530 nm. The LOD was 163 ng/band. After saponification the LOD of free 16-OMC was 43 ng/band. Thus 2 % robusta can be detected in a coffee blend.

Planta Medica 82(4), 371-376 (2016). TLC was applied to compare acetone – water 4:1 extracts from the mycelia and medium of fungus Trichoderma koningiopsis YIM PH 30002; an ethyl acetate fraction of each extract was separated on silica gel (mobile phase unknown) and visualized by three methods: detection with iodine reagent, sulfuric vanillin reagent, and phosphomolybdic acid in ethanol (8 %, w/v); no difference was found. Both extracts were then combined for the further isolation on columns of koninginins A, B and F, koningiopisins A–H, and trichodermaketone C._x000D_

Planta Med 83(05), 412-419 (2017). For the purification of verbascoside, the ethanol-water fractionation through size exclusion chromatography (Sephadex LH-20) of an 80 % ethanolic extract of Lippia citriodora leaves was monitored by TLC on silica gel with chloroform – methanol 7:3, followed by detection with vanillin sulfuric acid reagent.
