J. Liq. Chromatogr. Relat. Technol. 42, 249-257 (2019). Review of HPTLC methods published after 2000 for the analysis of vegetables, including bioactive compounds such as indoles, glycolipids, carotenoids and anthocyanins. TLC methods for the identification and quantification of pesticide residues such as iprodione, vinclozolin, cymoxanil, deltamethrin and parathion were reviewed. TLC coupled with other non-chromatographic techniques for the analysis of inorganic species, mycotoxins, glycoalkaloids and polyamides was described.
J. Liq. Chromatogr. Relat. Technol. 42, 274-281 (2019). HPTLC of caffeine in caffeine-containing botanicals and caffeinated products on silica gel with toluene - acetone - formic acid 9:9:2. Detection by dipping into NP reagent (1 g of diphenylborinic acid aminoethylester in 200 mL of ethyl acetate), followed by derivatization with anisaldehyde reagent, then heating at 100 ºC for 3 min. Quantitative determination by absorbance measurement at 273 nm. The hRF value of caffeine was 70. Linearity was between 30 and 120 ng/zone. The intra-day and inter-day precision was below 5 % (n=3). The LOD and LOQ were 10 and 30 ng/zone, respectively. Recovery rate was between 101 and 118 %.
J. Planar Chromatogr. 32, 191-196 (2019). HPTLC of phenolic compounds in 11 dark beers, 25 light beers, 10 non-alcoholic beers and 4 malt beers on silica gel with ethyl acetate - formic acid - acetic acid - water 50:55:55:13. Detection by dipping into a (1) 0.5 % methanolic solution of 2-aminoethyl diphenylborinate (natural product reagent or Neu’s reagent), followed by dipping into a 5 % methanolic polyethylene glycol (PEG) 400 solution for enhancement and stabilization of the fluorescent zones, or (2) 0.2 % methanolic DPPH radical solution. Documentation under white light and UV 366 nm. Zones at hRF values of 8, 13, 36, 45, 52 and 85 had the most impact on the principal component (PC) analysis and were recognized as markers for discrimination between dark and non-alcoholic beers. HPTLC-ESI-HRMS/MS2 analysis allowed the identification of desdimethyl-octahydro-iso-cohumulone (hRF 85) and iso-n/ad-humulone (hRF 95) as the most active bands with radical scavenging property.

J. Planar Chromatogr. 20, 407-410 (2007). TLC of the color pigments from different sorts of red wine (Cabernet Sauvignon, Merlot, and Burgundy) on RP-18 with acetonitrile - water - formic acid 20291 in a saturated chamber. Evaluation in visible light and under UV light at 366 nm, and by spraying with a methanolic solution of 0.5 mg/mL DPPH radical (2,2.diphenyl-1-picrylhydrazyl). Densitometric evaluation. RP-TLC is a tool for monitoring wine, for identification of the origin, and for detection of adulteration.
J. Liq. Chromatogr. Relat. Technol. 31, 1969-1976 (2008). TLC of urethane on spherical silica gel with methyl-t-butyl ether - methanol 73. 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.
Ecuadorian stingless bee (Meliponinae) honey A chemical and functional profile of an ancient health product. 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 100111127 and toluene - ethyl acetate - acetic acid 1091. Detection by fluorescence measurement at 400 nm and absorbance measurement at 240 nm, after fluorescence induction at 365 nm with a mercury vapor lamp.
