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.)

J. Liq. Chromatogr. Relat. Technol. 41, 364-372 (2018). TLC-DPPH test of gluten-free sheeted pasta supplemented with pomegranate seeds powder (PSP) on silica gel with ethyl acetate – water – acetic acid 8:1:1. Plates were immersed for 5 s in a freshly prepared 0.1 % methanolic DPPH solution and scanned every 10 min over an hour. The total areas under the peaks per track were measured and compared with the area obtained for rutin. Antioxidant properties of gluten free pasta correlated with the PSP content.

J. Chromatogr. 299, 460-464 (1984). Two-dimensional TLC of various triglycerides on Multi-K plates consisting of a strip of octadecyl-bonded silica along one side of a commercial silica plate. Development along the reversed-phase band with acetone - acetonitrile 4:1 (3 times) followed by dipping the plate into a 10 % silver nitrate solution in water - ethanol 1:1. Development in the second direction with toluene - ethanol 1:1. Detection with 5 % ammonium hydrogen sulfate and 7.5 % molybdophosphoric acid, both in water - ethanol 1:1. Method suitable for semi-quantitative analysis of fat samples.
