J. Liq. Chromatogr. Relat. Technol. 38, 1392-1406 (2015). HPTLC of Cordyceps sinensis and Ganoderma lucidum on silica gel with ethyl acetate - dichloromethane - formic acid - glacial acetic acid - methanol 10:10:1:1:2. Qualitative identification at UV 254 nm and UV 366 nm. Hyphenation of electronspray ionization/mass spectrometry with HPTLC facilitated fast and convenient profiling of the metabolites in the extracts. For the chemometric analysis, raw and column data matrices were constructed using hRF datasets.
J. Planar Chromatogr. 28, 157-161 (2015). HPTLC of neutral lipids (1) and polar lipids (2) on silica gel with petroleum ether - diethyl ether - glacial acetic acid 80:20:1 for (1) and with chloroform methanol - water 65:25:4 for (2). Detection with phosphomolybdic acid for (1) and cupric sulfate - phosphoric acid for (2). Quantitative determination by absorbance measurement at 610 nm for (1) and 370 nm for (2). The effects of both, high temperature and S. mansoni infection, had individual and combined deleterious effects on lipid metabolism of B. glabrata snails.

J. Planar Chromatogr. 28, 307-315 (2015). HPTLC of carbinoxamine (1), pholcodine (2) and ephedrine (3) in a pharmaceutical preparation on silica gel with chloroform - propanol - ammonia 60:40:1. Quantitative determination by absorbance measurement at UV 254 nm. The hRF values for (1) to (3) were 12, 30 and 42. Linearity was in the range of 0.5-9 ng/zone for (1), 1-10 ng/zone for (2) and 5-45 ng/zone for (3). LOD and LOQ were 0.1 and 0.4 ng/zone for (1), 0.2 and 0.6 ng/zone for (2) and 0.6 and 1.8 ng/zone for (3), respectively. Intra-day and inter-day precisions were below 2 % (n=3). Mean recoveries were around 101 % for (1) to (3). The HPTLC method was more simple, sensitive and economic than the HPLC method.
Rapid Commun. Mass Spectrom. 29, 474-484 (2015). The paper describes the modification of the standard Direct Analysis in Real Time mass spectrometry (DART) SVPA-3DS system for a reliable direct scanning of planar objects without the use of any internal standard. Optimization is focused on the substrate movement relative to the ion source outlet and the mass spectrometer inlet as well as substrate carrier and a special transfer tube. For the repeated DART-MS scanning along five identical deposited bands a mean precision of 2.7 % was obtained. A signal decay of 62 % was observed after five scans, which means that repeated analyses are possible at a decreasing signal intensity. After HPTLC of methyl-4-hydroxybenzoate and butyl-4-hydroxybenzoate, mean determination coefficients of 0.9937 and 0.9906 were obtained for five calibrations on five plates, respectively. The mean recovery of two control standards was 94 % with a mean repeatability of 9 % (n=5) obtained on five different plates.
PLoS ONE 9(1), e1003109 (2013). In order to understand how Borrelia burgdorferi acquires cholesterol from its host, five experiments were performed. HPTLC on silica gel with chloroform – methanol 17:3, the lipids were extracted through the Bligh and Dyer method: (1) from the spirochete incubated 4 h in a medium containing 4 mg/L BODIPY-cholesterol (fluorescing only in hydrophobic environment), (2) from the spirochete incubated 2 h in a medium containing 10 µCi/L tritiated cholesterol, (3) from HeLa cells incubated with the spirochete itself charged with tritiated cholesterol (after removal of all spirochetes). The same analysis was applied (4) to the purified outer membrane vesicles of the spirochete previously charged with BODIPY-cholesterol. In cases (1) and (4), UV detection showed that the BODIPY-cholesterol is incorporated into the cholesterol glycolipids of B. burgdorferi, whereas without incubation it has the same hRf as cholesterol. In cases (1), (2) and (4), iodine staining made free cholesterol and cholesterol-glycolipids (galactopyranosides) visible, but no other (cholesterol-free) lipids. In case (2), the chromatogram was sprayed with EN3HANCE Spray (DuPont), exposed using BioMax MR Film (Kodak) for 4 and 14 days at −80 °C and developed using a Medical Film Processor Model SRX-101A (Konica); the radiolabelled cholesterol was shown incorporated into the cholesterol-glycolipids. In cases (2) and (3), the radiolabelled zones on the layer were scraped off and analyzed by liquid scintillation counting; cholesterol-glycolipids were found (more than free cholesterol) transferred from the spirochete to the HeLa plasmalemma.
Food Control. 59, 700-707 (2016). HPTLC of aflatoxin B1 conjugated with carboxymethoxylamine hemihydrochloride (aflatoxin B1-CMO) on silica gel with chloroform - methanol 9:1 and 15 % acetic acid. Identification under UV light at 366 nm. The method was applied for conjugation with bovine serum albumin.
J. Liq. Chromatogr. Relat. Technol. 39, 242-248 (2016). Review of the application of multivariate TLC retention data, the theory of hierarchical cluster analysis, principal component analysis and parallel factor analysis. Different applications such as exploring retention, lipophilicity analysis, quantitative structure–activity relationship modeling, solvent selection and comparison with other techniques were described.
