J. Planar Chromatogr. 17, 51-53 (2004). TLC of gallic acid, salicylic acid and tannic acid on silica gel with chloroform - ethyl acetate - formic acid 5:4:1. Detection with the iron(III) - 2,2’-dipyridyl system (iron ammonium sulfate and sulfuric acid in water and 2,2’-dipyridyl in hydrochloric acid). Quantitative determination at 280 nm. Limit of detection 0.1 µg per spot.

Retention behaviour on polar adsorbents (silica, alumina, polyamide) with non-aqueous mobile phases. Acta Chrom. 9, 38-54 (1999). TLC of benzoic and cinnamic acid derivatives on silica gel 60 H compared with that on alumina oxide 60 G and polyamide layers with non-aqueous ternary mobile phases comprising a non-polar diluent (n-heptane), a polar modifier (2-propanol, dioxane, tetrahydrofuran and ethyl acetate) and 2 % acetic acid in horizontal chambers. Visualization under UV 254 nm, and by spraying with diazotized sulphanilic acid in 10 % sodium bicarbonate solution, or with a 2 % solution of ferric chloride. Chromatogram parameters and the correlation diagrams were used for comparison of separation selectivity.

Anal. Bioanal. Chem. 389, 827–834 (2007). A total extract of hen egg yolk is used as phospolipid mixture to demonstrate the capabilities. TLC of phosphatidylcholine, lysophosphatidylcholine, sphingomyelin, phosphatidylethanolamine, lysophosphatidylethanolamine and phosphatidylinositol on silica gel with chloroform - ethanol - water - triethylamine 5:5:1:5. Detection under UV 366 nm after spraying with primuline (Direct Yellow 59) reagent. Direct coupling MALDI-TOF MS and TLC can be easily implemented on commercially available MALDI-TOF devices. Roughly clean spectra without major contributions from fragmentation products and matrix peaks were obtained. This approach was sensitive enough to detect the presence of phospholipids at levels of less than 1 % of the total extract.

J. Liq. Chromatogr. Relat. Technol. 36, 2489-2496 (2013). HPTLC of neutral and polar lipids in Biomphalaria glabrata snails subjected to either Echinostoma caproni and Schistosoma mansoni miracidia coexposure, on silica gel with petroleum ether - diethyl eter 4:1 + 1 drop glacial acetic acid for neutral lipids and chloroform - methanol - water 65:25:4 for phospholipids. Detection by spraying with 5 % ethanolic phosphomolybdic acid for neutral lipids and 10 % cupric sulfate in 8% phosphoric acid for polar lipids. Quantitative determination by absorbance measurement at 610 nm and 370 nm for neutral and polar lipids, respectively.

PLoS ONE 10(10), e0140782 (2015). HPTLC of lipids, extracted from several cancerous cell lines by an adapted Bligh and Dyer’s method, on silica gel with chloroform – methanol 4:1. Detection under UV after spraying with thioflavine S (10 μg/mL in acetone 80 %), glycosylated lipids were hued in red-rose by spraying with orcinol 0.5 % in sulfuric acid 0.5 M followed by heating; some of those lipids were absent from the elisidepsin-resistant strains. These lipids were purified by scraping off the plate and by extracting with chloroform – methanol 2:1, then they were applied on a nitrocellulose membrane for an overlay assay for binding with an elisidepsin-biotin derivative (dot-blotting). One lipid was positive and was identified by NMR as probably a glucosylceramide.

Food Res. Int. 111, 361-370 (2018). HPTLC of triacylglycerols in unfermented and fermented cocoa beans on silica gel with hexane – diethyl ether – glacial acetic acid 80:20:1 and then with chloroform – methanol – glacial acetic acid 97:3:1. Detection by spraying with cerium molybdate reagent. Direct comparison of fermented and unfermented beans revealed the absence of cacaoic acid at hRf 55._x000D_

Lipids 17, 469-475 (1982). The total methyl esters of the fatty acids of tissue glycerides were converted into methoxy-acetoxy-mercury adducts. The adducts were fractionated into groups of equal numbers of ethylenic bands on silica with hexane - dioxane 6:4. Separation of the monoethylenic acids of equal chain length into the respective cis-and trans isomers by TLC on AgNO3-silica, acc. to known procedure.
