by the combination of high-performance thin-layer chromatography with direct bioautography and mass spectrometry. J. of Chromatogr. A 1422, 310-317 (2015). Investigation of two tansy (Tanacetum vulgare L.) essential oils, obtained by steam distillation of the capitula with subsequent liquid-liquid extraction (oil 1) or with use of an auxiliary phase for the trapping of the steam components (oil 2), against Bacillus subtilis F1276, B. subtilis spizizenii (DSM 618), Xanthomonas euvesicatoria, Pseudomonas syringae pv. maculicola, Ralstonia solanacearum strain GMI1000 and Aliivibrio fischeri by using the coupling of HPTLC to direct bioautography (HPTLC-DB). Oil 2 was richer in components and provided more inhibition zones due to the advanced extraction process. Identification of the main bioactive components by scanning HPTLC-direct analysis in real time mass spectrometry (HPTLC-DART-MS) and solid-phase microextraction GC electron impact MS (SPME-GC-EI-MS) as cis- and trans-chrysanthenol as well as trans-chrysanthenyl acetate. The results indicated that cis-chrysanthenol exhibited antibacterial effects against all tested bacteria. Trans-chrysanthenol inhibited B. subtilis, R. solanacearum and A. fischeri, and trans-chrysanthenyl acetate was an inhibitor for X. euvesicatoria, R. solanacearum and A. fischeri. However, the ionization characteristics and the recorded mass spectra showed that DART is a softer ionization technique than EI and more affected by ambient conditions and thus prone to additional oxidation products, although HPTLC-DART-MS resulted in a comparable fragmentation.
seed (Takhmaria). J. Planar Chromatogr. 29, 216-220 (2016). HPTLC of apigenin in the seeds of Ocimum basilicum on silica gel with toluene – acetone – formic acid 5:4:1. Quantitative determination by absorbance measurement at 340 nm. The hRF value of apigenin was 71. Linearity was in the range of 100-600 ng/zone. Intermediate precisions were below 0.5 %. The LOD and LOQ were 4 and 12 ng/zone. Recovery was between 98.5 and 100.6 %.
J. Agric. Food Chem. 64, 1245-1255 (2016). Preparative HPTLC of gangliosides in the frontal lobe of piglets on silica gel with chloroform – methanol – calcium chloride 50:42:11. Fractions were subjected to a series of reactions to obtain sialic acid, glucose, galactose, N-acetyl-galactosamine, and fatty acid derivatives.
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.
CBS 116, 9-10 (2016). HPTLC of herbal slimming drugs and the standard orlistat on silica gel with toluene – ethyl acetate 4:1 with chamber saturation (with filter paper) to the migration distance of 70 mm. Detection by dipping in phosphomolybdic acid reagent (5 g in 100 mL ethanol) and heating at 110 °C for 5 min. Evaluation under UV 254 nm, 366 nm and white light. Quantitative determination by absorbance measurement at 195 nm before derivatization to detect illegally added orlistat in the herbal drugs. The LOD of orlistat standard was 70 ng/band.
J. Sep. Sci. 39, 4258-4262 (2016). TLC of 35 model compounds on RP-2, RP-8, RP-18, alumina, cellulose, cyano, diol, amino phase, and silica gel with 20 pure solvents (acetone, acetonitrile, 1-butanol, 1-chlorobutane, chloroform, cyclohexane, 1,2-dichloroethane, dichloromethane, dioxane, ethanol, ethyl acetate, heptane, hexane, methanol, isooctane, 1-propanol, 2-propanol, t-butyl methyl ketone, tetrahydrofuran, and toluene). Parallel factor analysis was used to study the retention phenomena in quantitative manner.
fruits. J. Planar Chromatogr. 29, 356-360 (2016). HPTLC of gallic acid (1), vanillic acid (2), protocatechuic acid (3), and quercetin (4) in the fruits of Limonia acidissima on silica gel with toluene – ethyl acetate – formic acid 5:4:1. Quantitative determination by absorbance measurement at 254 nm. The hRF values of (1) to (4) were 30, 47, 37 and 42, respectively. Linearity was between 100 and 600 ng/zone for (1) to (4). The intermediate precisions for (1) to (4) were below 1.6 % (n=3). The LODs and LOQs were 30 and 91 ng/zone for (1), 25 and 76 ng/zone for (2), 33 and 100 ng/zone for (3) and 28 and 85 ng/zone for (4). Recoveries were between 98.0 and 100.1 % for (1) to (4).
