CBS 104, 13-15 (2010). HPTLC of aloeverose, glucose and galactose in aloe vera products on silica gel (impregnated with NaH2PO4) with acetone - iso-propanol - 0.1 M formic acid 2:2:1 (double development for products with high glucose content). Detection by immersion in 4-aminobenzoic acid reagent (1 g 4-aminobenzoic acid in 36 mL acetic acid, with 40 mL water, 2 mL 85 % phosphoric acid and 120 mL acetone), followed by heating at 100 °C for 10 min. Densitometric evaluation by fluorescence measurement at 366 nm. The limit of quantification was approx. 3 % in aloe vera products. RSD for polynomial calibration is 2.1 % for mannose in the range of 8-80 ng/band and 4.0 % using matrix calibration.

J. Chromatogr. 360, 397-406 (1986). TLC of 6-o-alpha-D-glucosyl-, 6-0-alpha-maltosyl and 6-o-alpha-maltotriosyl derivatives of alpha, beta- and gamma cyclodextrin (CD) and of 6,6'-di-o-alpha-D-glucocyl-beta-CD on 4 kinds of plates with different solvent systems. Chromatography on silica with 1-propanol - ethyl acetate - water, 25 % NH3 3:1:2:1, on NH2-bonded silica with acetonitrile - water 3:2, on Si 50000 silica with 1-butanol - pyridine - water 6:4:3. TLC is a more convenient method than HPLC for the analysis of CDS.

Anal. Chem. 73, 3804-3807 (2001). TLC of lipopolysaccharides from intact bacteria on silica gel with chloroform – methanol – water – triethylamine 12:6:1:0.04. Detection by spraying with 10 % sulphuric acid in ethanol followed by heating at 150 °C for 5 min. For the non-destructive visualization the plates were pre-washed twice with propanol – water 1:1 and developed in methanol – water 1:1 which made the products appear as dull white spots on a bright background. Zones containing lipopolysaccharides or lipid A molecular species were isolated from the plate and analyzed by MALDI mass spectrometery.

Bioorg. Chem. 38, 56-61 (2010). TLC of 4-methoxyphenyl glycoside on silica gel with acetonitrile - methanol - water 4:2:1. Detection by spraying with warm 2 % ceric sulphate in 2N sulfuric acid. The hRf of 4-methoxyphenyl glycoside was 30.

(Mucopolysaccharides of cotton flowers). Dtsch. Apoth. Ztg. 127, 665-669 (1987). After acidic hydrolysis, TLC on silica with acetonitrile - water 85:15. Staining with aniline - diphenylamine - phosphoric acid reagent. The following sugars were identified: D-galacturonic acid, D-glucoronic acid, D-galactose, D-glucose, D-mannose, L-arabinose, D-xylose and L-rhamnose.

Biochem. Biophys. Res. Commun. 397, 87-92 (2010). Preparative TLC of the hydrolysis reaction of maltodextrin glycosidase on various substrates (maltotriose, alpha-, beta-, gamma-cyclodextrins and cycloamylose) on silica gel with ethyl acetate - methanol - acetic acid - water 12:3:3:1. The structure of the products was determined by MALDI-TOF/MS, 13C NMR, and enzymatic analysis.

(Chinese). Chinese J. Adv.in Biochem.& Biophys. 2, 64-66 (1987) (Shengwu Huaxue Yu Shengwu Wuli Jinzhan). TLC on cellulose with n-butanol - acetic acid - 2M NH4OH 2:3:1. Detection under UV at 260 nm. Identification by comparison of Rf values to standards.

J. Planar Chromatogr. 23, 46-49 (2010). HPTLC of polysaccharides (with galactose, glucose, mannose, arabinose, ribose, xylose, rhamnose, galacturonic acid, and glucuronic acid as standards) before and after hydrolysis on silica gel with chloroform - n-butanol - methanol - water - acetic acid 9:25:10:3:3 with chamber saturation for 30 min at room temperature. Detection by spraying with aniline - diphenylamine - phosphoric acid reagent and heating at 130 °C for 10 min. Quantitative determination by absorbance measurement at 380 nm. Ninhydrin reagent was used for detection of other compounds.
