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. Liq. Chromatogr. Relat. Technol. 39, 303-307 (2016). HPTLC fingerprinting of 27 white wines of three sorts on silica gel with ethyl acetate – formic acid – acetic acid – water 10:1:1:2 and on RP-18 with methanol – water – formic acid 50:50:1. Detection by heating at 100 °C for 3 min, followed by dipping into Natural Product reagent (1 g of diphenylborinic acid aminoethylester dissolved in 200 mL ethyl acetate) and after drying by dipping into PEG reagent (10 g of polyethylene glycol 400 dissolved in 200 mL dichloromethane). Qualitative identification under UV 254 nm and UV 366 nm.

Food Control. 70, 119-129 (2016). HPTLC of aflatoxins AFB1, AFB2, AFG1 and AFG2 in Brazil nut (Bertholletia excelsa) on silica gel with toluene – ethyl acetate – formic acid 5:4:1. Qualititative identification under UV light at 366 nm.

J. Chromatogr. A 1529, 93-106 (2017). Presentation of the quantitative effect-directed profiles of 77 industrially and freshly extracted botanicals like herbs, spices, vegetables and fruits, widely used as food ingredients, dietary supplements or traditional medicine for their quality assessment with regard to potential health-promoting activities. Fast assignment of single active compounds and evaluation of their contribution to the overall activity, originating from a food or botanical sample by combination of HPTLC hyphenated with UV/Vis/FLD detection and effect-directed analysis, using the 2,2-diphenyl-1-picrylhydrazyl radical, Gram-negative Aliivibrio fischeri, Gram-positive Bacillus subtilis, acetylcholinesterase and tyrosinase assays. Characterization of bioactive compounds of interest eluted using an elution head-based interface by HPTLC-UV/Vis/FLD-EDA-ESI-(HR)MS method. Demonstration of the excellent quantification power of the method by applying for rosmarinic acid, contents ranged from 4.5 mg/g (rooibos) to 32.6 mg/g (rosemary), for kaempferol-3-glucoside from 0.6 mg/g (caraway) to 4.4 mg/g (wine leaves), and for quercetin-3-glucoside from 1.1 mg/g (hawthorn leaves) to 17.7 mg/g (thyme). The mean repeatabilities (%RSD, n=18) were ≤ 2.2 % for the three compounds and the mean intermediate precision (%RSD, n=3) was 5.2 % over three different days.

J. Chromatogr. A 1530, 211-218 (2017). Development of a novel and cost-effective TLC method on cellulose (instead of silica gel) for authentication of selected fruit-based alimentary products. As authenticity markers the anthocyanins cyanin chloride, keracyanin chloride, pelargonidin chloride and delphinidin chloride were used. With TLC, the LOD and LOQ for cyanin were of 25 and 75 ng/zone, for keracyanin 55 and 166 ng/zone, for pelargonidin 47 and 140 ng/zone, and for delphinidin 171 and 513 ng/zone. With HPTLC the LOD and LOQ for cyanidin were 107 and 321 ng/zone, for keracyanin 189 and 566 ng/zone, and for pelargonidin 161 and 484 ng/zone (delphinidin was not detectable). Consequently, quantification of anthocyanes in the alimentary products by TLC allowed identification of more target compounds and in a higher number of alimentary products than by HPTLC. (Note that original HPTLC method in J Chromatogr A 1299 (2013) 105-118 was reported to be more sensitive (mainly 3-50 ng/zone) and with higher correlation coefficients of calibration curves (0.9993-0.9999) for 11 anthocyanins/-cyanidins than the HPTLC method that was reproduced in this paper.)
