      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).
