J. Liq. Chromatogr. Relat. Technol. 31, 1969-1976 (2008). TLC of urethane on spherical silica gel with methyl-t-butyl ether - methanol 7:3. Detection by immersion in a solution of 80 µL cinnamaldehyde in 40 mL acetone with 2.4 mL phosphoric acid followed by heating in an oven at 130 °C for 10 min. The fluorescence can be enhanced by the factor of 2 if the plate is dipped for 4 s into a solution of 10 % polyethylene glycol 600 in methanol. Quantitative determination by absorbance measurement in the range of 445 to 460 nm.
Food Chem. 114, 1413-1420 (2009). HPTLC of methanolic fractions of stingless bee honey samples and commercial samples from Apis mellifera (European honey bee) on silica gel with a five step development with two different mobile phases: ethyl acetate - formic acid - acetic acid - water 100:11:11:27 and toluene - ethyl acetate - acetic acid 10:9:1. Detection by fluorescence measurement at 400 nm and absorbance measurement at 240 nm, after fluorescence induction at 365 nm with a mercury vapor lamp. Detection of flavonoids by spraying with an aqueous solution of 4 % aluminium sulphate. Flavonoids and coumarins were identified by comparison with commercial standards.
J. Planar Chromatogr. 22, 127-131 (2009). HPTLC of 6-gingerol, extracts of Suprabha and market samples of ginger on silica gel (prewashed with methanol) with n-hexane - acetone 18:7 in a twin trough chamber saturated for 4 min at 20 +/- 4 °C and 36 +/- 3 % relative humidity. Quantitative determination by absorbance measurement at 286 nm. The limit of detection and quantification was 40 and 150 ng/band, respectively.
J. Planar Chromatogr. 23, 230-232 (2010). HPTLC of (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, (-)-epigallocatechin gallate, (-)-epicatechin gallate, procyanidin B2, procyanidin A2, and methylxanthines (theobromine and caffein) on cellulose with n-propanol - water - acetic acid 20:80:1 in a horizontal chamber. Detection by dipping for 1 s into 4-dimethylaminocinnamaldehyde detection reagent. Quantitative determination by absorbance measurement at 655 nm. By densitometry LOD for (-)-epicatechin and procyanidin B2 was 0.2 and 2 ng/zone, respectively; LOQ was 0.4 ng and 4 ng/zone, respectively. These limits were lower by a factor 50 for (-)-epicatechin and by a factor of 10 for procyanidin B2 than those obtained by HPLC. The TLC method gave a more accurate result for the (-)-epicatechin content of baking chocolate than the HPLC method which was also more time-consuming.
J. Planar Chromatogr. 23, 400-405 (2010). OPLC of fructose, glucose, and sucrose in 31 different types of wine (white and red; dry, semi-dry, semi-sweet, and sweet) on silica gel with acetontrile - water 13:2 (as the best of 6 mobile phases tested) under isocratic conditions in overrunning operation mode. Detection by spraying with a mixture of aniline and diphenylamine. Quantitative determination by absorbance measurement at 420 nm.
J. of Chromatogr. A 1218 (37), 6540-6547 (2011). New approach and application of highly automated planar chromatographic tools for powerful clean-up, called high-throughput planar solid phase extraction (HTpSPE), which is indispensable for preventing matrix effects in multi-residue analysis of pesticides in food by liquid and gas chromatography coupled to mass spectrometry, employing TLC to completely separate pesticides from matrix compounds and to focus them into a sharp zone, followed by extraction of the target zone by the TLC-MS interface, thus resulting in extracts nearly free of interference and free of matrix effects, as shown for seven chemically representative pesticides in four different matrices (apples, cucumbers, red grapes, tomatoes), and completion of clean-up of one sample in a manner of minutes. Regarding the clean-up step, quantification by LC–MS with mean recovery (against solvent standards) of 90–104% and relative standard deviations of 0.3–4.1% (n = 5) for two spiking levels of 0.1 and 0.5 mg/kg.
J. Planar Chromatogr. 24, 53-56 (2011). HPTLC of the pesticides temephos and fenitrothion on silica gel, prewashed with methanol, with acetone - hexane 3:7 in an unsaturated twin-trough chamber. Quantitative determination by densitometry in absorbance mode at 290 nm. The hRf values were 55 and 69. LOD was 20 ng for temephos and 10 ng for fenitrothion. Recovery was 80-107 % with relative standard deviations of 4.4-20.2 %.
J. Planar Chromatogr. 25, 138-144 (2012). HPTLC of diosmin (1) and hesperidin (2) on silica gel with ethyl acetate - methanol - water - acetic acid 25:2:2:1. Quantitative determination by absorbance measurement at 330 nm. Linearity was in the range of 100-3000 ng/zone for (1) and 250-7500 ng/zone for (2). The method did not show any statistically significant deviation when compared with a validated HPLC.
