CBS 112, 2-4 (2014). TLC and HPTLC of chamomile (Matricaria recutita L.) flowers and standards herniarin, umbelliferone, alpha-bisabolol, and spiroethers on silica gel with chloroform - acetone 99:1 or dichloromethane up to 90 mm (TLC) and 75 mm (HPTLC). Detection under UV 254 and 366 nm and after dipping in vanillin reagent (0.4 % ethanolic vanillin solution with 2 % sulfuric acid) or DPPH radical reagent (0.02 % methanolic 2,2-diphenyl-1-picrylhydrazyl) for information on radical scavenging activity. Biological detection by dipping individually in a suspension of Bacillus subtilis, Aliivibrio fischeri, Pseudomonas syringae pv. maculicola and Xanthomonas vesicatoria. The essential oil component chamazulene showed the strongest antioxidative capacity.
J. Agric. Food. Chem. 63, 2893-2901 (2015). HPTLC of lecithins such as phosphatidylcholine (1) and phosphatidylethanolamine (2) in soybean and sunflower used for chocolate production on silica gel with chloroform - methanol - water - ammonia 30:17:2:1. Detection by dipping into a primuline solution (100 mg of primuline in 200 mL of acetone - water, 4:1). Quantitation by fluorescence measurement at UV 366 nm. The hRF values of (1) and (2) were 30 and 41-43, respectively. Quantitation was also performed by HPTLC-positive ionization electrospray ionization mass spectrometry (ESI-MS) and by scanning HPTLC-matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOFMS). Mean LODs ranged from 8 to 40 mg/kg for HPTLC-FLD, 10 to 280 mg/kg for HPTLC-ESI and 15 to 310 mg/kg for HPTLC-FLD-ESI-MS.
J. Chromatogr. Sci. 55, 961-968 (2017). Presentation of two accurate, precise and highly selective stability-indicating methods for simultaneous determination of benztropine mesylate (BNZ) in presence of its hepatotoxic and carcinogenic degradation product, benzophenone (BPH) either in pure form or in the pharmaceutical formulation without any preliminary separation steps. TLC of BNZ and its degradation product on silica gel with hexane – methylene chloride – triethylamine 25:25:3. Quantitative determination by densitometry at 235 nm. The linearity was between 1.5-10 μg/band and 1-10 μg/band for BNZ and BPH, respectively. UPLC of the mixture on a RP C8 analytical column, quantification using a diode array detector at 210 nm. The linearity with UPLC was 20-200 μg/mL and 5-50 μg/mL for BNZ and BPH, respectively. Comparison of the results showed no significant differences between the TLC and UPLC method regarding both accuracy and precision.
Lipids 17, 448-452 (1982). Purification of hexadecyl cholesteryl ether by silica column chromatography for removing the majority of unreacted hexadecylmethane sulfonate and dihexadecyl ether by-product. TLC on silica with hexane - ether acetic acid 80:20:1. Typical overall product yield 60-80 % of the theory. Product resistant to acid hydrolysis in 7 % HCl in methanol for 4 h at 60 °C, conditions that hydrolize cholesteryl oleate.
J. Chromatogr. 321, 145-157 (1985). TLC of the title compounds on different types of silica with butanol - ethanol - water, or butanol - pyridine - water in various proportions. Detection by spraying with a reagent containing aniline (4 ml), diphenylamine (4 g), acetone (200 ml), and 85 % phosphoric acid (30 ml), followed by heating at 80 °C for 30 min. Also HPLC.
J. Chromatogr. 351, 379-382 (1986). TLC of plant extracts containing the xanthone-C-glycoside mangiferin on silica with ethyl acetate - formic acid - water 67:13:20. Densitometric determination at 366 nm. Also TLC of colladin and colladonin with benzene - MEK - formic acid 9:1:1. Comparison with HPLC. Method suitable for the quantitative determination of other xanthone glycosides and coumarins in plant extracts.
J. Chromatogr. 410, 53-76 (1987). Study of the separation of 32 alkyl-substituted phenoxyalkanoic acids from phenoxy-acetic to 3- pentadeoxylphenoxylauric acid by TLC using water, formamide or liquid paraffin as stationary phases, and chemically bonded phases. Observation of the differences of their suitability for separation of lower or higher homologues and their detection sensitivity. Discussion of the optimal methods in the separation, detection, and limit of detection.
serrata, B. carteii, and B. papyrifera. J. Chromatogr. 27, 127-133 (1989). TLC on silica with dichloromethane - acetone 98:2. Detection by spraying with 1M antimony pentachloride in chloroform, heating at 120°C; day light or UV 365 nm. Also GC and GC/MS.
