J. Microchem. 37, 174-180 (1988). TLC of cholesterol, cholesteryl formate, cholesteryl acetate, cholesteryl propianate on silica with 5 solvent systems (e.g. hexane - chloroform - ether - methanol - acetic acid 2:15: 60:5:2 or hexane - chloroform - ether - methanol - acetic acid - 1-propanol 920:15:6:2:2:3. Detection by spraying with 30 g copper acetate in 80 mL H3PO4 made up to 1 L and heating at 130°C for 5 min.

J. Chromatogr. 532, 449-452 (1990). TLC on silica with petrol ether - ethyl acetate - acetic acid 80:20:1. Detection by spraying with vanillin - sulfuric acid 1:100 (w/v) and heating at 85 °C for 6 min. Quantification by densitometry at 525 nm using external standards.

J. Liquid Chromatogr. 18, 527-535 (1995). HPTLC of cholesterol esters, triacylglycerols, free fatty acids, and cholesterol on silica with petrol ether (37.5 - 52 °) - ether - acetic acid 80:20:2, and hexane - petrol ether - ethyl ether - acetic acid 50:20:2:1. Detection by spraying with 5% phosphomolybdic acid in ethanol and heating at 110-120 °C for 5-10 min. Quantification by densitometry at 700 nm.

Planta med. 66, 681-684 (2000). TLC of 26,27-dihydroxy-5?-lanosta-7,9(11),24-triene-3,22-dione and 26-hydroxy-5a-lanosta-7,9(11),24-triene-3,22-dione on silica gel with chloroform - methanol 49:1. Visualization by spraying with vanillin - sulfuric acid reagent.

J. Liq. Chromatogr. Relat. Technol. 30, 2629-2634 (2007). TLC of ergosterol, stigmasterol, dihydrocholesterol, 4-cholesten-3-one, cholecalciferol, and cholesterol acetate on silica gel using methanol - dichloromethane 1:19 in a saturated horizontal chamber. Detection by spraying twice with 10 % phosphomolybdic acid in methanol and heating. Contrary to the data reported in literature, the experiments revealed that the best conditions for robust detection of these analytes are achieved if the TLC plates are heated at relatively low temperatures (between 40 and 80 °C) and for longer times (more than 20 min).

J. Chromatogr. A 1530, 192-196 (2017). HPTLC to measure the antioxidant and hypoglycemic effects in different extracts from Myrmecodia platytyrea, which can be a traditional medicine as alternative treatment for diabetes, because the substances produced by ants can reduce blood sugar levels. Measurement of the antioxidant activity in methanol, ethanol, dichloromethane (DCM) and ethyl acetate (EA) extracts with the HPTLC-2,2-diphenyl-1-picrylhydrazyl free radical (DPPH*) assay, and of the hypoglycemic effects with a newly developed α-amylase inhibitory activity assay. Detection of stigmasterol after derivatization with anisaldehyde reagent as purple colored zone under white light at hRF 66. The results showed the highest antioxidant activity in the ethanol extract rich in polyphenols and flavonoids. No antioxidant activity but significant α-amylase inhibitory activity was observed in the DCM extract. The highest α-amylase inhibitory activity was found in the EA and DCM extracts and was related to their stigmasterol content.

Proc. Intern. Symposium on TLC with special Emphasis on OPLC, Szeged, 83-84 (1984). TLC of ecdysteroids on silica with a) chloroform - dichloromethane - methanol 85:10:5, b) ethyl acetate - methanol - NH3 85:10:5. Detection by UV. Method of choice for screening.

J. Planar Chromatogr. 1, 78-80 (1988). Comparison of the interlaboratory tests for TLC and HPTLC determination of cholesterol by using different stationary and mobile phases, different developing chambers and various postchromatographic derivatization procedures. Discussion of the repeatability, accuracy and reproducibility for determining cholesterol in a synthetic mixture.
