Planta med. 65, 455-457 (1999). Preparative TLC on silica gel plates of 2-(4-hydroxyphenyl)ethyl 1-dodecyl-octadecanoate on silica gel with hexane - ethyl acetate 7:3 and of ursolic acid with chloroform - ethyl acetate 5:2. Detection under UV 254 nm.

J. Planar Chromatogr. 15, 463-465 (2002). HPTLC and TLC of 3,5-dihydroxybenzoic, vanillic, p-coumaric, p-hydroxybenzoic, gentisic, caffeic, syringic, sinapic, ferulic, protocatechuic, and 2,4-dihydroxybenzoic acid on silica gel and RP-18. Detection under UV 254 and 366 nm and by derivatization with bis-diazotized sulfanilamide. One-dimensional HPTLC was performed on RP-18 with methanol - water 2:3 and on silica gel with toluene - dioxane - formic acid 7:2:1 and a gradient of decreasing polarity and formic acid concentration. Documentation by densitometry. 2D-TLC on silica gel with toluene - dioxane - formic acid 7:2:1 in the first direction and, after drying, with a three step gradient elution program in the second direction. TLC on RP-18 was used in the first direction with methanol - water 2:3 After the first development the phenolic acids were transferred to the second silica gel plate with 70% methanol. TLC in the perpendicular direction was then performed with a three-step gradient elution program. The combined methods resulted in separation of all compounds investigated.

CBS 86, 4-5 (2001) HPTLC of 3-methoxy-4-amino azo meta sulphonic acid (MAMASA) on silica gel with n-butanol - diethylamine - ammonia - methanol 9:5:5:2 with chamber saturation for 5 min followed by drying at 40 °C. Quantitative determination by absorbance measurement at 254 nm.

TLC of oleic, elaidic, ricinolic acid, methyl ricinoleate, alpha-hydroxy-palmitic acid, methyl alpha-hydroxypalmitate, 12-hydroxystearic acid, methyl 12-hydroxystearate, 9,10-dihydroxystearic acid, and methyl 9,10-dihydroxystearate on RP18 with methanol; methanol - water 19:1 and methanol - water 9:1. Detection with iodine vapor.

J. High Resol. Chromatogr. 7, 593-595 (1984). HPTLC of the title compounds on silica with ethanol - ether - ethyl acetate - chloroform 12:33:22:33. Detection by spraying with 5 % cupric acetate in 15 % aqueous phosphoric acid and heating at 110 °C for 10 minutes. Fluorometry at 366 nm. Sensitivity 1-10 ng.

J. Liq. Chromatogr. Relat. Technol. 31, 1871-1880 (2008). HPTLC for the determination of neutral lipid profils using a standard mixture (containing cholesterol, oleic acid, triolein, methyl oleate, cholesteryl oleate) on silica gel (plates with 19 scored lanes and a preadsorbent application area, prewashed by development with dichloromethane - methanol 1:1) with petroleum ether - diethyl ether - acetic acid 80:20:1 in a saturated twin-trough chamber. Detection by spraying with 5 % ethanolic phosphomolybdic acid and heating for 10 min at 115 °C. Quantitative determination by absorbance measurement at 610 nm.

J. Sep. Sci. 36, 1317-1326 (2013). HPTLC of 1. aflatoxine G1; 2. ochratoxine A; 3. zearalenone; 4. quinine; 5. cinconine, 6. hydroquinine; 7. o-(4-chlorobenzoyl) hydroquinine; 8. hydroquinine 4-methyl-2-quinolyl ether; 9. (DHQ)2 Phal; 10. (DHQ)2 AQN and 11. camptothecin on RP-18, RP-8, and RP-2 with 85 to 95 % methanol in steps of 2.5 %. In the case of the other stationary phases, the methanol fraction modification was of 5 %. The methanol fraction ranged from 75 to 95 % for RP-18 W, from 35 to 55 % for amino phase, from 50 to 70 % for diol phase, and finally from 65 to 85 % for cyano phase. Qualitative identification by absorbance measurement at 254 and 366 nm. The lipophilicity indices indicated that the mRM appears to be the most suited descriptor.

Int. Arch. Otorhinolaryngol. 19, 141-150 (2015). HPTLC of phosphatidylcholines (1), cholesterol (2), and triacylglycerols (3) in mastoid tissue on silica gel with chloroform - methanol - water 65:25:4. Detection by spraying with orcinol (0.02 % in 50% sulfuric acid), followed by heating at 120 ºC for 3 min. To estimate the blood contamination in the extracts, the plate was further stained with Coomassie Brilliant Blue G-250 (0.03 % in 30 % methanol/100 mM NaCl) and destained with methanol (30 % in 100 mM NaCl). The contribution of blood to the lipid profiles of the tissue was insignificant. The hRF value for (1) was in the range of 0-24, and for (2) and (3) in the range of 70-100.
