CBS 82, 9-11 (1999). HPTLC-AMD of glucose, maltooligosaccharides, anhydrosugars, transglycosidation products, fructose and its derivatives, maltulose, Amadori-compounds and Heyns-compounds on silica gel. Caramelization: isocratic 23-step gradient based on chloroform - methanol - 0.05 % aqueous boric acid 20:11:2 with 3 mm increments of the developing distance. Maillard-reaction: isocratic 3-step gradient chloroform - dichloromethane - methanol - water 35:15:35:6 over 25, 50, 75 mm developing distance. Detection by dipping in aniline-diphenylamine-phosphoric acid reagent, followed by heating at 120 °C for 10 min. Quantification by absorbance measurement at 385 nm.

CBS 108, 9-11 (2012). HPTLC of fructose, galacturonic acid, rhamnose, xylose, and galactose in samples of agar agar, arabic gum, carubin, guaran, traganth, xanthan, pectin, alginic acid, alginates and carrageen on silica gel with i-propyl acetate - ethyl acetate - methanol - water 50:40:10:1 to a migration distance of 60 mm. Densitometric absorption measurement at 370 and 630 nm and peak area evaluation by linear or polynomial regression. Detection by immersion in aniline diphenylamine o-phosphoric acid reagent (20 % o-phosphoric acid (85 %) added to 1:1 mixtures of 2 % solutions of diphenylamine and aniline in acetone) and heating at 110 °C for 5 min. Comparison of HPTLC with GC gave comparable results, however, the HPTLC method is more effective in terms of sample throughput, robustness, costs and analysis time (8 times faster than GC).
