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.

Hungarian Scientific Instruments 62, 11-16 (1986). Step-gradient OPTLC separation of gangliosides and lipid samples from leukaemic cells on silica. Acidic lipid fraction 70 mm with chloroform - methanol 7:3 followed by 140 mm with chloroform - methanol - 0.25 % KCl in water 55:36:9. Total lipid extract 40 mm with chloroform - methanol 95:5, 130 mm with chloroform - methanol - water 65:25:3 and 220 mm with chloroform - methanol - 0.25 % KCl in water 55:36:9. Remark by referee: should be called "displacement chromatography".
