I. Regular part of the model. J. Planar Chromatogr. 4, 460-466 (1991). Manual examination of the retardation behavior of 16 apolar, closely related coumarins in normal phase TLC using the regular part of the three-dimensional „PRISMA“ model. The results show a highly significant second order dependency between the retardation factor (Rt) and the solvent strength (vertical correlation), as well as between the retardation factor and the selectivity point (horizontal factor).

J. Planar Chromatogr. 8, 243-344 (1995). TLC of 15 oxygen-containing adamantanes on alumina with chloroform - acetone - methanol 36:12:1, chloroform - acetone 6:1, carbon tetrachloride - acetone 30:7 or chloroform - acetone 18:6 or on silica with chloroform - methanol 50:3 or 14:1. Detection by exposure to iodine vapor.

Phytochemical Analysis 9, 71-74 (1998). Separation of a complex mixture of neolignans by reversed phase prep. TLC on RP-18 with 40% aqueous methanol. Final purification by prep. TLC on neutral alumina with multiple developments with ethyl acetate - petroleum ether 1:3.

Planta med. 65, 74-76 (1999). Peparative TLC of 15 lignans (i. a. gomisin N, A, B, K3, J, L2, benzoylisogomisin O, angeloylgomisin H, sigloylgomisin P, schisandrin, schisantherin, licarin A, D, machiline G, GERI-BP001/M) on silica gel with 20 - 40% ethyl acetate - hexane.

Planta med. 68, 1066-1071 (2002). TLC of (-)-epicatechin, (+)-catechin, procyanidin-B2, and procyanidin-C1 on silica gel with ethyl acetate - acetic acid - formic acid - water 75:2:3:20. Detection by UV light at 254 and 366 nm and by spraying with vanillin-sulfuric acid reagent (1 % vanillin in methanol and 5 % sulfuric acid in ethanol).

J. Chromatogr. A 1530, 211-218 (2017). Development of a novel and cost-effective TLC method on cellulose (instead of silica gel) for authentication of selected fruit-based alimentary products. As authenticity markers the anthocyanins cyanin chloride, keracyanin chloride, pelargonidin chloride and delphinidin chloride were used. With TLC, the LOD and LOQ for cyanin were of 25 and 75 ng/zone, for keracyanin 55 and 166 ng/zone, for pelargonidin 47 and 140 ng/zone, and for delphinidin 171 and 513 ng/zone. With HPTLC the LOD and LOQ for cyanidin were 107 and 321 ng/zone, for keracyanin 189 and 566 ng/zone, and for pelargonidin 161 and 484 ng/zone (delphinidin was not detectable). Consequently, quantification of anthocyanes in the alimentary products by TLC allowed identification of more target compounds and in a higher number of alimentary products than by HPTLC. (Note that original HPTLC method in J Chromatogr A 1299 (2013) 105-118 was reported to be more sensitive (mainly 3-50 ng/zone) and with higher correlation coefficients of calibration curves (0.9993-0.9999) for 11 anthocyanins/-cyanidins than the HPTLC method that was reproduced in this paper.)

Acta Chimica 112, 401-410 (1983). TLC of 1-(2-OR-phenyl)-3-(2-benzofuryl)-propenone; 1-(2-OR-phenyl)-3-(5-benzofuryl)-propenone; 2-(3,6-dimethyl-2-benzofuryl)-3-hydroxy-6-methylchromone; 2-(2-benzofuryl)chromone; 3-(2-benzofuryl)chromone on silica with benzene - ethanol 9:1. Detection by UV 254 nm.

Helv.Chim. Acta 70, 1551-1557 (1987). TLC of new naphthoxirene derivatives on silica with chloroform - methanol 85:15 or chloroform - methanol - water 65:35:5 and HPTLC on RP-8 with different methanol/water mixtures. Detection under UV 254 nm. The fungicidal activity was determined with a TLC bioassay using Cladosporium cucumerinum.
