Baill., on silica gel with petroleum ether (30-60 °C) – ethyl formate – formic acid 15:5:1, detection under UV 254 nm.
J. Planar Chromatogr. 29, 405-409 (2016). 2D-HPTLC of chlorogenic acid (1), rutin (2), caffeic acid (3), apigenin (4) and naringin (5) in ten samples of the selected Cirsium species on RP-18 with 2-butanone ‒ toluene ‒ acetic acid 9:10:1 used in the first direction and methanol ‒ water ‒ formic acid 4:5:1 used in the second direction. Detection by spraying with natural products reagent (1 g diphenylborinic acid 2-aminoethylester in 100 mL methanol) followed by PEG reagent (5 g PEG 4000 in 100 mL methanol). The hRF values were 71 for (1), 39 for (2), 57 for (3), 7 for (4) and 50 for (5) in the first direction and 36 for (1), 7 for (2), 82 for (3), 86 for (4) and 6 for (5) in the second direction.
J. Planar Chromatogr. 29, 477-479 (2016). HPTLC of baygon (1), carbaryl (2) and carbofuran (3) on silica gel with hexane ‒ ethyl acetate 9:1. Detection by spraying with 10 % sodium hydroxide solution followed by o-toluidine reagent (5 g o-toluidine dissolved in 14 mL HCl and filled up to 100 mL with distilled water) combined with 10 % sodium nitrate. The hRF values were 48 (orange) and 51 (faint violet) for (1), 46 (orange) for (2) and 46 (violet) and 49 (violet) for (3). _x000D_
J. Planar Chromatogr. 30, 106-112 (2017). RP-HPTLC (1) and micellar liquid chromatography-TLC (2) of 1,2,4-triazole derivatives on RP-18 with methanol and acetonitrile in volume range concentration between 0.3 and 0.65 organic modifier for (1) and sodium dodecyl sulfate concentrations above critical micellar concentration in the range between 0.0318 and 0.1318 mol/L for (2). Detection by exposure to iodine vapors at room temperature. Developments were performed in moderate (≈0.4 T) magnetic field and simultaneously outside it. The partition coefficient P value of the investigated substances was used as a descriptor of their lipophilic properties.
J. Ethnopharmacol. 197, 157-164 (2017). HPTLC of picroside I (1) and picroside II (2) in Picrorhiza kurroa on silica gel with ethyl acetate – methanol – acetic acid 46:1:1. Quantitative determination by absorbance measurement at 270 nm. The hRF values for (1) and (2) were 52 and 68, respectively.
J. Chromatogr. Sci. 54 (7), 1096-1104 (2016). TLC of the extracts of the dried aerial parts of 12 plants of Cirsium species and five selected standards (naringin, apigenin, rutin, caffeic acid and chlorogenic acid) on silica gel with ethyl acetate – formic acid – acetic acid – water 24:3:3:8 on RP-18 phase with 5 % aqueous solution of formic acid – methanol 7:3 for the first development and the same system in the ratio of 1:1 for the second development. Analysis of the results by chemometrics. The comparison of individual Cirsium species and the identification of unknown species by using the similarity indices (Pearson's correlation coefficient, determination coefficient and congruence coefficient), distance indices (Euclidean distance, Manhattan distance and Chebyshev's distance) and Multi-Scale Structural SIMilarity. Based on chemometric analysis, the first extract of the widely grown species is identified as Cirsium arvense and the second one as Cirsium rivulare.
natural polymers and planar chromatographic stationary phases
J. Planar Chromatogr. 30, 440-452 (2017). For electroseparation experiments in a commercially available, open-air electrophoresis box, thirteen types of separation layers (filtrating paper, office paper, chromatography paper, Japanese paper for aircraft paper models, potato starch on cellulose support, common HPTLC glass plates coated with cellulose, silica gel, RP-18W, and aluminum oxide as well as glass-based nutrient agar layers) were investigated. The best separation was observed for the cellulose pre-coated TLC layer and the starch layer on filtrating paper support. The study revealed substantial differences between the electrophoretic migration of target dyes within cellulose type layers and also in comparison to the remaining stationary phases studied. Combined planar electrophoresis–electrochromatography of methyl red and ponceau R colorants on active thin-layers composed of starch powder on cellulose strips and agar layer on glass-based support connected with electrolyte containers. The resulting dye pattern on active layers was acquired using an office scanner.
CBS 117, 11-12 (2006). For the rapid control of the fish species escolar (Lepidocybium flavobrunneum) by determination of the indigestible wax esters, HPTLC on silica gel with n-hexane – toluene 7:3 with chamber saturation for 10 min, migration distance 60 mm. Detection by dipping in aqueous Rhodamine B reagent (0.025 %), evaluation under UV 366 nm. Quantitative determination by fluorescence measurement at 366/>400 nm with the Hg lamp. The hRF value of oleyl oleate was 30 and of stearyl stearate 40. The mean recovery rate (104 %) was determined by analyzing salmon samples spiked to contain 20 % wax esters. The wax ester content of an escolar sample was 18-22 % (n=3). The repeatability was <5 % and the mean laboratory precision 3 %.
