J. Planar Chromatogr. 10, 406-410 (1997). To study the relationship between chemical structure and retention behavior in TLC on silica, the retention constants of variously substituted 1,2-O-isopropylidene derivatives of aldohexoses and 1,2-O-cyclohexylidene derivatives of aldopentoses were measured as a function of the composition of eight binary mobile phases. The slopes and intercepts of the linear relationships between the retention constant (RM) and the logarithm of the volume fraction of the polar mobile phase component were calculated and are discussed in relation to solute and mobile phase characteristics. The RF values and relative retention of compounds depend largely on the retention behavior of their substituents.

J. Planar Chromatogr. 15, 449-453 (2002). Possible explanation of a detection process HPTLC of D-(+)-glucose, D-(+)-galactose, and D-(-)fructose on NH2-phase with 1-propanol - nitromethane - water 5:3:2. Detection after drying for 24 h and heating at 130 - 140°C for 3-4 min and inspection under UV 366 nm. It is suggested that during heating the analytes probably undergo a process which results in a structural transformation possibly analogous to the Maillard reaction.

Food Chem. 77, 263-265 (2002). HPTLC of trehalose on silica gel, impregnated with phosphotungstic acid of pH 2.5, with n-butanol – pyridine – water 8:4:3. Detection by spraying with a solution of 6.5 mM N-(1-naphthyl)-ethylenediamine dihydrochloride in methanol, containing 3 % sulfuric acid. The hRf values of raffinose, trehalose, maltose, sucrose, glucose, and fructose were 30, 41, 46, 53, 55, and 59, respectively.

E-Journal of Chemistry 7(51), 5559-5565 (2010). TLC of sucralose in commercially available tabletop sweeteners, dietetic sweets and soft drinks on silica gel with chloroform - methanol - toluene 10:7:3 (system 1) and chloroform - ethanol - benzene 5:3:2 (system 2). The hRf value of sucralose was 62 with system 1 and 45 with system 2. Detection by dipping in rhodamine-sulphuric acid reagent, followed by heating at 120 °C for 3 min. The band corresponding to sucralose appears as olive-green band with ?max at 456 nm. The fluorescence property of the sucralose derivative can be used for quantitative analysis (?max 366 nm). The method is highly reproducible as other carbohydrates and artificial sweeteners don’t produce a fluorescent olive-green color with this reagent. The method was applied to cola drinks, lemon juices, sugar free sweets, and tabletop sweeteners with excellent results. The LOD was 5-7 ng/band and linearity was in the range of 40-250 ng/band for both methods.

J. Planar Chromatogr. 30, 170-174 (2017). HPTLC-overpressured layer chromatography of monosaccharides (glucose, xylose, rhamnose, and arabinose) as substrates and sugar alcohols (xylitol, sorbitol and arabitol) as metabolites, to follow the fermentation of the yeast Candida tropicalis DSM 7524 on silica gel with acetonitrile – acetic acid – water 63:33:5. Detection by dipping for 9 s into a reagent containing 5 mL of solution I (2 % basic acetate of lead (IV) in glacial acetic acid) and 5 mL of solution II (0.2 % 2,7-dichlorofluorescein in 100 mL ethanol) made up to 200 mL with toluene, followed by heating at 105 °C for 3 min. Quantitative determination by absorbance measurement at 366 nm.
