J. Planar Chromatogr. 19, 21-26 (2006). HPTLC of protocatechuic and caffeic acid on silica gel using mixtures of heptane, diisopropyl ether, dichloromethane, and formic acid as mobile phases for multiple gradient development. Quantitation by scanning in absorbance/reflectance mode at 320 nm for caffeic acid and at 260 nm for protocatechuic acid.

Comparison of the extrapolated Rm values. J. Chromatogr. 347, 209-218 (1985). Rm determination of a series of prostaglandins in two reversed-phase TLC systems, the mobile phase being an aqueous buffer alone or mixed-with various amounts of methanol or acetone. Discussion of the relationship between chromatographic behaviour and mobile phase composition. The extrapolated Rm values are independent of the nature of the organic solvent

J. Liq. Chromatogr. Relat. Technol. 31, 1881-1891 (2008). HPTLC of various neutral lipid classes on silica gel (prewashed with dichloromethane - methanol 1:1) with petroleum ether - diethyl ether - acetic acid 80:20:1 in a twin trough chamber saturated for 20 min. Detection by spraying with 5 % ethanolic phosphomolybdic acid solution and heating for 10 min at 110 °C. Quantitative determination by absorbance measurement at 610 nm.

J Vet Sci Med Diagn 2(3), 1-3 (2013). HPTLC of neutral lipids on silica gel (HLF plates with 19 scored channels of 9 mm width) prewashed with dichloromethane - methanol 1:1 and heated for 30 min at 120 °C, with petroleum ether - diethyl ether - glacial acetic acid 80:20:1 with chamber saturation. Detection of dark zones on a yellow background after spraying with 5 % ethanolic phosphomolybdic acid reagent. Quantification of triacylglycerols by absorption measurement at 610 nm with polynomial regression via peak area.

Food Sci. Technol. Campinas. 35, 598-604 (2015). TLC of phosphatidylglycerol (1), phosphatidic acid (2), phosphatidylethanolamine (3), phosphatidylinositol (4), phosphatidylcholine (5) and lysophosphatidylcholine (6) in the seeds of flaxseed (Linum usitatissimum) on silica gel with chloroform - acetone - methanol - acetic acid - water 10:4:2:2:1. Detection by exposure to iodine vapours and evaluation in daylight. Solid phase extraction was performed to characterize the phospholipid composition during flaxseed development.

J. Chromatogr. A 1558, 69-76 (2018). Development of an HPTLC method for monoacylglycerols (MAG), diacylglycerols (DAG), triacylglycerols (TAG) and free fatty acids (FFA) in E 471 food emulsifiers, as a simple, rapid, sensitive and convenient screening alternative to HPLC and GC analysis. HPTLC of the samples in t-butyl methyl ether on primuline pre-impregnated LiChrospher silica gel by two-fold development, first with diethyl ether to 18 mm, then with n-pentane – n-hexane – diethyl ether 13:5:7 to 75 mm. Quantitative determination by fluorescence measurement at UV 366/>400 nm, using the cumulative signal for each lipid class and 1,2-distearin for calibration. The amounts of the lipid classes were calculated using response factors and expressed as monostearin, distearin, tristearin and stearic acid. The LOD and LOQ for 1,2-distearin were 1 and 4 ng/zone, respectively. The visual detection by fingerprint enabled an easy characterization and the direct comparison of emulsifiers through the lipid class pattern.
