J. Planar Chromatogr. 28, 167-172 (2015). TLC of trans-resveratrol in cosmetic raw materials on RP with methanol - water 3:2. The plate is dried for 3 h. Quantitative determination by fluorescence measurement using a deuterium lamp at 340 nm. The hRF value was 38. The LOD and LOQ were 2 and 6 ng/zone, respectively. The presence of trans-resveratrol in the analyzed samples was additionally confirmed by detection with anisaldehyde reagent.
J. Planar Chromatogr. 7, 211-216 (1994). TLC of the individual dye components of a hair color product (eight different variations of the formula) on silica with ethyl acetate or ether - chloroform - ethyl acetate 6:1:1. Quantification by densitometry at 415 nm (absorbance).
Separation Science and Technology 44, 1007-1021 (2009). A TLC method for mutual separation of three longchain aliphatic quaternary ammonium halides (cationic surfactants) is reported. TLC of dodecyltrimethyl ammonium bromide (DTAB), tetradecyltrimethyl ammonium bromide (TTAB) and hexadecyltrimethyl ammonium chloride (HTAC) on laboratory made TLC plates coated with Kieselguhr (0.25 mm), with methanol - 10 % sodium formate 3:7 as mobile phase. Detection with modified Dragendorff reagent comprised of solution A (containing bismuth subnitrate and KD) and solution B (containing barium chloride). Solutions A and B were mixed 2:1. The compounds appeared as orange-coloured spots. The effects of alcohols (ethanol, n-propanol), substitution of the formate ion by benzoate and acetate ion, different adsorbents (silica gel, aluminum), and the interference of metal ions ( Cu2+, Zn2+, Hg2+, Co2+, Pb2+) on the resolution of the three surfactants was studied. The limits of detection of DTAB, TTAB, and HTAC estimated were 3.3, 3.1, and 2.8 µg/zone respectively. The method was applied for separation of these compounds in water samples.
TrAC 66, 146-157 (2015). Review of common analytical techniques and methods for the analysis of adulterants of essential oils. HPTLC methods for the analysis of numerous samples, such as Clary sage, Mint, Neroli, Niaouli and Thyme essential oils are referenced.
J. Planar Chromatogr. 8, 39-46 (1995). TLC of 11 nitrosamines and amines on CN and diol modified silica with four binary eluents: cyclohexane - dioxane, heptane - ethyl acetate, isooctane - MTBE, cyclohexane - 2-propanol. Detection by spraying with sodium nitroprusside - potassium hexacyanoferrate (II) reagent resp. ninhydrin.
CBS 105, 10-12 (2010). HPTLC of stratum corneum lipids (ceramides, cholesterol, phosphatidylcholine, squalene, sphingomyelin etc.) on silica gel by automated multiple development with a 8-step gradient from methanol to hexane in the AMD2 with pre-conditioning with 4M acetic acid before step 6. Detection by immersion in copper(II)sulfate reagent followed by heating at 170 °C for 8 min. Quantitative determination by absorbance measurement at 600 nm. Phosphatidylcholine and sphingomyelin remain at the start position, all other substances are separated.
CBS 115, 5-7 (2015). HPTLC of xanthones in mangosteen fruit (Garcinia mangostana) on RP-18 with acetonitrile – water – formic acid 80:17:3 to a migration distance of 65 mm. Detection by spraying with NEU's reagent and PEG, evaluation under UV 366 nm. The hRf value of β-mangostin was 11, of 9-hydroxycalabaxanthone 14, of α-mangostin 29, and of γ-mangostin 43. Quantitative determination of the four xanthones as α-mangostin equivalents by absorbance measurement at 280 and 320 nm. Comparison with an HPLC-UV method on RP-18 showed only a small difference (1.5 %) of the quantified total content. HPTLC was found to be a good alternative to HPLC.
J. Planar Chromatogr. 9, 136-137 (1996). TLC of benzylideneacetone on RP-18 silica with methanol - water 7:3. Quantification by densitometry at 285 nm. Sensitivity 0.0050% for visual screening and 0.0017% for quantification by direct spotting.
