TLC of natural and synthetically-modified carbohydrate gums after acid hydrolysis at 110 °C for 2.5 h on silica with 1-propanol - water - NH3 79:20:1 for hydrolyzed gums and 94:5:1 for synthetically modified gums. Detection by spraying with 0.1M p-anisidine and 0.1M phthalic acid in methanol and heating at 105 °C for 10-15 min.

J. Planar Chromatogr. 5, 131-133 (1992). TLC of rhamnose, xylose, arabinose, mannose, glucose, galactose, glucuronic acid, galacturonic acid on silica impregnated with phosphate buffer (0.2M, pH 6.8) with acetonitrile - amyl alcohol - water 6:2:2. Detection by spraying with a solution of N-(1-naphthyl)ethylene diamine dihydrochloride (30 mg in 10 mL of a solution of 5 % sulfuric acid in methanol) followed by drying for 10 min at 100 °C. Quantification in the nanogram range by densitometry at 580 nm.

Anal. Biochem. 287, 337-339 (2000). Visualization of glycoconjugates by spraying with diphenylamine-aniline-phosphoric acid reagent. Heating for 25 min at 120?C. Sensitive reagent for neutral sugars, sialic acids, 3-deoxy-D-manno-octulosonic acid, 2-keto-3-deoxy-D-glycero-D-galactonononic acid, and hexosamines found in glycoconjugates (cello- and chito-oligosaccharides, neutral glycosphingolipids, gangliosides).

Acta Chromatographica 6, 7-14 (1996). HPTLC of fructose, glucose and sucrose on a channeled silica gel plate with concentration zone with acetonitrile - water 17:3 for three times (freshly prepared each time, taking 15 min per run) with chamber saturation for 10-15 min. Before, just the silica gel layer was impregnated by spraying with 0.10 M sodium bisulfate solution, and subsequently with citrate buffer (1:10 dilution of citrate buffer with water, pH 4.8), each followed by drying. Detection by spraying with 1-naphthol-sulfuric acid reagent, followed by heating at 100-110 °C for 5-10 min. Quantitative determination by absorbance measurement at 515 nm. The hRf values of fructose, glucose and sucrose were 47, 43, and 28, respectively, and selectivity regarding matrix was given. No zones other than the sugars were detected in sample chromatograms because of the selectivity of the detection reagent and the retention of the beverage components in the preadsorbent. Correlation coefficients (r) for linear regression of the calibration curves typically ranged from 0.90-0.99, with an average of 0.97. The precision in matrix was 2.5 % (n = 5). The mean reproducibility of the twofold sample analyses was 4 %, ranged between 0.45 % and 7.5 %. The accuracy of the method was 94.6 %, 97.0 % and 90.8 % for sucrose, glucose and fructose, respectively. Sugar concentrations in the samples ranged from 18.4-34.3 mg/mL.

J. Planar Chromatogr. 27, 449-453 (2014). HPTLC of the glycome of different species of Panax (P. ginseng, P. notoginseng, and P. quinquefolium). Monosaccharides were analyzed on cellulose phase with ethyl acetate - pyridine - acetic acid - water 35:15:1:7 for the first development and 35:15:1:9 for the second development. Detection by spraying with aniline-O-phthalic acid reagent (containing 1.6 g o-phthalic acid dissolved in 100 mL water-saturated n-butanol, containing 0.9 mL of aniline), followed by heating at 105 °C for 5 min. Oligosaccharides were analyzed on silica gel with n-butanol - isopropanol - acetic acid - water 7:5:1:2. Detection by spraying with diphenylamine–aniline–phosphoric acid solution (4 g diphenylamine mixed with 4 mL aniline and 20 mL 85% (v/v) phosphoric acid in 200 mL acetone), followed by heating at 105 °C for 5 min._x000D_
