J. of Chromatogr. A 1218 (24), 3811-3815 (2011). HPTLC of sugars in bio-oil fractions on silica gel with acetonitrile - water 4:1, or mixtures of butanol and formic acid, followed by detection with the aniline - diphenylamine - o-phosphoric acid reagent. The method allowed for the separation of the anhydrosugars levoglucosan and cellobiosan, as well as glucose, arabinose, xylose and cellobiose without the need of pre-treatment and pre-derivatization of samples. Volatile compounds present in bio-oil did not interfere with sugar analysis, and the detrimental effect of the complex bio-oil matrix on columns and detector lifetime is avoided by using disposable HPTLC plates. It was found that the concentrations of levoglucosan and cellobiosan in bio-oil samples obtained from Pinus radiata sawdust were ranged between 1.3-2.3 % and 1.0-2.0 % respectively, while a higher levoglucosan concentration was in a bio-oil sample obtained from native wood.

(Purity test of sorbose and sorbitol with thin-layer chromatography on Silufol ready made plates.) Pharmazie 39, 689-690 (1984). Sorbitol and sorbose are separated from concomitant substances such as glucose and/or fructose, disaccharides and trisaccharides. The silica layer pretreated with 2O mM solution of sodium pyrosulfate, then developed with 1-propanol - ethyl acetate - water 27:3.5:1 and visualized after drying at 100 °C by spraying with lead tetraacetate.

J. Planar Chromatogr. 19, 418-421 (2006). TLC of fructose, glucose, saccharose, maltose, maltotriose, maltotetraose, maltopentaose, maltohexaose on silica gel in a pre-saturated twin-trough chamber with chloroform - carbon tetrachloride - 35 % aqueous formic acid - methanol 20:5:17:22. After drying the chromatogram was immersed in a solution of sulfuric acid reagent (10 mL conc. sulfuric acid in 200 mL of a cooled 1:1 mixture of 1-propanol and carbon tetrachloride) and heated for 8 min at 108 °C. Quantitative determination by absorbance measurement at 290 nm.
