Detection under UV 254 nm.
J. Liq. Chromatogr. Relat. Technol. 30, 2253-2265 (2007). HPTLC of 17 flavonoids (caffeic acid, ferulic acid, flavone, naringenin, apigenin, acacetin, luteolin, hesperitin, catechin, epicatechin, hyperoside, hesperidin, quercitrin, narinin, rutin, resveratrol, kaempferol) on silica gel (prewashed with acetone) with 28 binary and ternary mobile phases with chamber saturation. Detection by derivatization with diphenylborinic acid 2-aminoethyl ester (natural products reagent) and evaluation under UV 366 nm. Also coupling of HPTLC and HPLC.
Part I. Nicotinic acid and its amides. J. Liq. Chromatogr. Relat. Technol. 30, 2317-2327 (2007). TLC and HPTLC of nicotinic acid, nicotinamide, N-methylnicotinamide, and N,N-diethylnicotinamide on RP-18 with methanol - water 3:7, and dioxane - water 1:4 and 1:9. The best separation was achieved on alumina with acetone - n-hexane 1:1. Detection under UV light at 254 nm. Quantitative determination by absorbance measurement at 254 nm.
J. Liq. Chromatogr. Relat. Technol. 31, 2019-2034 (2008). TLC of captopril, delapril, enalapril, lisinopril, amd moexipril on silica gel (impregnated by continous development with 10 % paraffin oil in n-hexane for 18 h) and RP-18 with various mobile phases. Detection under UV 254 nm. TLC is a fast and economical method for the determination of lipophilicity.
Anal. Chem. 76, 3251-3262 (2004). This review covers the literature of TLC/HPTLC found in Chemical Abstracts and ICI Web of Science from November 1, 2001 to November 1, 2003. Review Contents: 1. History, Student Experiments, Books, and Reviews; 2. Theory and Fundamental Studies; 3. Chromatographic Systems (Stationary and Mobile Phases); 4. Apparatus and Techniques; 5. Detection and Identification of Separated Zones; 6. Quantitative Analysis; 7. Preparative-Layer Chromatography and Thin-Layer Radiochromatography 8. Literature Cited.
Acta Chromatographica 9, 79-86 (1999). HPTLC (TLC) of glucose, maltose, sucrose and trehalose on silica gel with acetonitrile - water 17:3 and ethyl acetate – acetic acid – methanol – water 12:3:3:2 for three times with chamber saturation; on amino plates with ethyl acetate – pyridine – water – acetic acid 12:6:2:1 and on cellulose plates with ethyl acetate – pyridine – water 2:1:2, both in a non-equilibrated chamber; on RP-18 with tetrahydrofuran – water 44:6 in a pre-equilibrated chamber. All plates were prewashed, e.g. by chromatography with dichloromethane - methanol 1:1. Detection by 4-aminobenzoic acid reagent, 1-naphthol–sulfuric acid reagent or aniline–DPA reagent, each followed by heating at 110 °C for 10 min. The combined results from comparison of hRf values for two different mobile phases on silica gel, on cellulose, amino phase and C18-bonded layers with diverse separation mechanisms, spiking experiments on silica gel, detection with selective reagents, and GC–MS analysis definitely proved the presence of maltose and glucose and the absence of trehalose in digestive gland–gonad complex and hemolymph samples from B. glabrata. Earlier papers reporting the presence of trehalose were undoubtedly in error.
Anal. Chem. 79, 2101-2108 (2007). TLC of benzodiazepines (midazolam, diazepam, lorazepam, oxazepam, N-desalkyl-flurazepam, triazolam, nitrazepam) on monolithic UTLC phase (prewashed with methanol) with dichloromethane - acetone 93:7 for one-dimensional and toluene - acetone - ethanol - 25 % ammonia 70:20:3:1 for two-dimensional separation in a saturated chamber. Developing distance 2 cm; separation time for 1-D chromatography 2-6 min, for 2-D 4-12 min. Quantitative determination by absorbance measurement at 254 nm; for visual detection the analytes were derivatized by spraying with Dragendorff reagent. Identification of the separated compounds by AP-MALDI-MS. The limits of detection were in the picomole range and thus low enough for bioanalysis.
