J. Liq. Chromatogr. Relat. Technol. 38, 1142-1146 (2015). HPTLC-DPPH of instant grits with Chamomilla anthodium as additive prepared by extrusion method on silica gel with acetonitrile - water - choroform - formic acid 12:3:2:1. Detection by dipping into 0.2 % chloroformic DPPH solution for 5 s followed by keeping in the dark for 30 min.
J. Planar Chromatogr. 28, 316-322 (2015). HPTLC of pyridostigmine bromide in pharmaceutical formulations on silica gel with methanol - ethyl acetate - triethyl amine - glacial acetic acid 180:20:10:1. Quantitative determination by absorbance measurement at 270 nm. The hRF values for pyridostigmine bromide and its alkaline degradation product were 14 and 34, respectively. Linearity was in the range of 2-10 ng/zone. LOD and LOQ were 1.9 and 0.6 ng/zone, respectively. The intermediate precision was 0.8 % (n=9). Recoveries ranged between 98 and 100 %.
Rapid Commun. Mass Spectrom. 29, 1242-1252 (2015). The paper describes the application of adding neon into helium for Direct Analysis in Real Time (DART) leading to plasma glow visualization to track the metastable gas distributions during surface scanning. The method allows for optimal selection of the coordinates for DART-MS analysis without loss in signal intensity. Visualization of the impact region of the excited gas stream is of high importance for further developments of planar chromatographic hyphenations with DART-MS.
Food Res. Int. 76, 3-10 (2015). HPTLC of saponins in peas (Pisum sativum) on silica gel with chloroform - methanol - water 55:37:8. Detection by dipping into p-anisaldehyde sulfuric acid reagent for 2 s, drying for 10 min, followed by heating at 70 °C for 5 min. Quantitative determination by absorbance measurement at 545 nm. The hRF of soyasaponin βg was 60 as a violet-blue band and for soyasaponin I 57 as an orange band on a dark background. Saponin identification by hyphenation of HPTLC with mass spectrometry (MS) via a TLC–MS interface.
J. Liq. Chromatogr. Relat. Technol. 38, 1546-1554 (2015). HPTLC of aliskiren (1), amlodipine (2), and hydrochlorothiazide (3) on silica gel with ethyl acetate - methanol - ammonia 375:140:11. Quantitative determination by absorbance measurement at 229 nm. The hRF values for (1) to (3) were 43, 29 and 65, respectively. Linearity was in the range of 1500-5250 ng/zone for (1), 50-175 ng/zone for (2) and 125-432 ng/zone for (3). LOD and LOQ were 133 and 404 ng/zone for (1), 14 and 43 ng/zone for (2) and 12 and 36 ng/zone for (3), respectively. The intermediate precision was below 1.5 % (n=6). Recovery was found in the range of 99-101 %, 99-100 %, and 100-101 % for (1) to (3), respectively.
J. Planar Chromatogr. 29, 108-112 (2016). HPTLC of water-soluble vitamins (B1, B2, B6, C, and B12), amino acids and β-blocker enantiomers (carvedilol, (S)-(−)-propranolol hydrochloride, (±)-propranolol hydrochloride, and (±)-sotalol hydrochloride) on novel core–shell polymers consisting of hyperbranched (poly(ethyleneimine)) core surrounded by oligosaccharide shell (PEI-OS) as a component of the silica gel phase. The influence of the weight of the hyperbranched PEI core (5 and 25 kDa) was investigated. β-blocker enantiomers were separated using acetonitrile - methanol 7:3. PEI-maltose and PEI-lactose were the most effective polymers for the chiral separation of β-blockers.
J. Liq. Chromatogr. Relat. Technol. 39, 322-324 (2016). HPTLC of neutral (1) and polar lipids (2) in Biomphalaria glabrata snails on silica gel with petroleum ether – diethyl ether – glacial acetic acid 80:20:1 for (1) and chloroform – methanol – water 130:50:9 for (2). Detection of neutral lipids by spraying with 5 % phosphomolybdic acid in absolute ethanol and polar lipids using 10 % copper (II) sulfate in 8 % phosphoric acid.
CBS 116, 13-15 (2016). HPTLC of nicotine in e-liquids on silica gel with chamber saturation (with filter paper) for 20 min with toluene – acetone –diethylamine 10:10:1 to the migration distance of 70 mm. Detection under UV 254 nm. Quantitative determination by absorbance measurement at 260 nm. Elution of the zones with methanol (with 0.1 % formic acid) into a single quadrupole MS and detection in positive ionization mode. The hRf value of nicotine was 56 and separation from other ingredients (propylene glycol, glycerol, flavors) was good. Visual evaluation of the samples for presence of nicotine was confirmed with MS and UV spectra.
