Detection by spraying with a methanolic solution of diphenylamine, aniline, and ortho-phosphoric acid, followed by heating at 140 °C for 2-3 min. Quantitative determination by absorbance measurement at 600 nm. The hRF values for (1) to (5) were 55, 50, 31, 11 and 46, respectively. Linearity was between 100 and 500 ng for (1) to (5). The intermediate precision was below 2 % (n=3). The LOD and LOQ were 22 and 66 ng for (1), 13 and 40 ng for (2), 51 and 155 ng for (3), 13 and 39 ng for (4) and 76 and 229 ng for (5), respectively. Average recovery was 97.9 % for (1), 99.9 % for (2), 99.3 % for (3), 98.3 % for (4) and 97.8 % for (5).

J. Planar Chromatogr. 18, 285-289 (2005). HPTLC of glucose - after hydrolyis of starch using alpha-amylase and amyloglucosidase - on silica gel, pre-washed with methanol, treated by immersion in a 0.1 M solution of di-potassium hydrogen phosphate in methanol and activated for 30 min at 120 °C. Three-fold development was performed in a horizontal development chamber with acetonitrile - water 173. Detection by dipping in aniline-diphenylamine reagent, densitometry at 520 nm. Calibration was linear between 100 and 300 ng with a coefficient of determination r2 of 0.9959. The limits of detection and quantification for starch as glucose were 0.26 and 0.51 g/100 g, respectively.

HPTLC of an equimolar mixture of malto-oligosaccharides, derivatized with p-aminobenzoic acid, on silica gel with acetonitrile – water – acetic acid 821. Quantitative determination by fluorescence measurement at 366 nm. The relative molar composition of the oligomers, determined by HPTLC, was used as a reference data for mass spectrometric analyses. For both electrospray ionization and matrix-assisted laser desorption/ionization methods, the instrumental parameters significantly influence the signal intensities and areas.
