using high-performance thin-layer chromatography. J. Planar Chromatogr. 31, 309-317 (2018). HPTLC of gardenin-E (1), gardenin-D (2), xanthomicrol (3), 5-desmethynobiletin (4), gardenin-A (5), and gardenin-B (6) in the sum resin of Gardenia lucida on silica gel with n-hexane – diethyl ether – 1,4-dioxane 4:6:1. Detection by dipping into natural product reagent (10 mL of 1 % methanolic diphenyl boryloxyethylamine), followed by dipping into PEG reagent (8.0 mL of 5 % ethanolic polyethylene glycol 4000). Quantitative determination by absorbance measurement at 335 nm. Linearity was between 0.33 and 1.67 μg/zone. LOD and LOQ were 90 and 300 ng for (1), 90 and 290 ng for (2), 90 and 320 ng for (3), 100 and 320 ng for (4), 60 and 210 ng for (5) and 80 and 280 ng for (6), respectively. The intermediate precision was <2 %. Recovery ranged from 96.0 to 99.3 %.
J. Planar Chromatogr. 31, 367-376 (2018). HPTLC of folic acid (1) in the presence of its impurities pteroic acid (2) and para-amino benzoic acid (3) on silica gel with methanol – iso-propanol – water – glacial acetic acid 90:5:5:2. Quantitative determination by absorbance measurement at 280 nm. Linearity ranged between 0.4-4 μg/zone for (1), 0.1-1.5 μg/zone for (2) and 0.2-1.8 μg/zone for (3). LOD and LOQ were 132 and 398 ng/zone for (1), 33 and 99 ng/zone for (2) and 66 and 199 ng/zone for (3), respectively. The intermediate precision was <2 % (n=3). Average recovery was 100.0 % for (1), 98.6 % for (2) and 100.7 % for (3). Results obtained by the HPTLC method showed no significant difference when compared with those obtained by applying the reported RP-HPLC method.
J. Planar Chromatogr. 31, 397-403 (2018). HPTLC of clozapine (1) and aripiprazole (2) on silica gel with toluene ‒ methanol ‒ ethyl acetate ‒ ammonia 65:25:10:1. Quantitative determination by absorbance measurement at 218 nm. The hRF values for (1) and (2) were 43 and 60, respectively. Linearity was between 200 and 1600 ng/zone for (1) and 100 and 800 ng/zone for (2). LOD and LOQ were 34 and 103 ng/zone for (1) and 20 and 60 ng/zone for (2), respectively. The intermediate precision was <2 % (n=3). Recovery ranged between 98.2-99.9 % for (1) and 98.7-99.5 % for (2).
Proc. Intern. Symposium on TLC with special Emphasis on OPLC, Szeged, 93, (1984). TLC and OPTLC of L-lysine, formaldehyde on silica with citrate buffer pH 6.1. Detection with ninhydrin and heating at 80 °C for 10 minutes. Densitometry.
J. Chromatogr. 295, 141-151 (1984). TLC of various primycin preparations on silica with chloroform - methanol - acetone - water 28:42:14:16, chloroform - methanol - water 45:45:10, chloroform - methanol - formic acid - water 50:35:14:1, propanol - acetic acid - water 7:1:2 and other solvent systems. Detection with vanillin/sulfuric acid. Densitometry after detection at 590 nm. Also two-dimensional TLC using numerous solvent systems and PLC.
R.E. Kaiser (Ed) "Proc. of the 3rd Int. Symp. on Instr. HPTLC, Wuerzburg" IfC, Bad Duerkheim 1985, 373-380.Description of the method,, which can be used for detection, identification and quantification in both absorbance and fluorescence. Application example from drug analysis (anthraquinone type, laxative).
Comparison with a GC technique. R.E. KAISER (Ed) "Proc. of the 3rd Int. Symp. on Instr. HPTLC, Wuerzburg", IfC, Bad Duerkheim (1985), 233-246. HPTLC of DDT and DDE extracted from plant material on silica with hexane - ether 9:1. Detection by immersing in 0.1 % diphenylamine ethanolic solution. Activation of the chromatogram for 30 min. under UV at 366 nm. Quantification by fluorometry at 366 nm. Comparison with GC.
J. Chromatogr. 315, 395-400 (1984). Reversed-phase HPTLC of gangliosides GT 1b, GD 1a, GD 1b, Fuc-GM1, GM1 and AM2 on C18-bonded silica with methanol - acetonitrile - water 196.5:1.
