J. Chromatogr. A 1432, 140-144 (2016). 2-Aminoacetophenone (AAP) is closely correlated with the appearance of the sensory phenomenon of untypical aging off-flavor (UTA) in wine and is generally analyzed by GC/MS after being extracted from wines by liquid-liquid, solid-liquid or solid phase microextraction. Presentation of a rapid, selective and sensitive method for the determination of AAP in wine by HPTLC of the extracts, obtained by liquid-liquid extraction with t-butyl methyl ether followed by a basic cleanup, on amino layer with methylene chloride – toluene 7:3. Detection by dipping into n-hexane-paraffin solution and quantification by densitometry at 366/>400 nm using 2-amino-4-methoxyacetophenone as internal standard. The LOD and LOQ were 0.1 and 0.3 μg/L, respectively. The recovery was near 100 % for model, white and red wines, while AAP concentrations were >0.5 μg/L in UTA. The results indicated that the method enables the analysis of AAP in wines clearly below the odor thresholds and represents a rapid and convenient screening alternative to existing GC/MS methods.
CBS 116, 9-10 (2016). HPTLC of herbal slimming drugs and the standard orlistat on silica gel with toluene – ethyl acetate 4:1 with chamber saturation (with filter paper) to the migration distance of 70 mm. Detection by dipping in phosphomolybdic acid reagent (5 g in 100 mL ethanol) and heating at 110 °C for 5 min. Evaluation under UV 254 nm, 366 nm and white light. Quantitative determination by absorbance measurement at 195 nm before derivatization to detect illegally added orlistat in the herbal drugs. The LOD of orlistat standard was 70 ng/band.
J. Ethnopharmacol. 193, 490-499 (2016). HPTLC of quercetin in the leaves of Ocimum basilicum on silica gel with toluene – ethyl acetate – formic acid 17:11:2. Quantitative determination by absorbance measurement at 254 nm.
J. Chromatogr. Sci. 54 (3), 318-325, (2016). TLC of cetylpyridinium chloride, chlorocresol and lidocaine in oral antiseptic formulation on silica gel with methanol – acetone – acetic acid 35:15:1. Densitometric evaluation at 215 nm. Statistical comparison between the results obtained with this method and a RP-HPLC method using F- and t-tests showed no significant difference.

J. Ethnopharmacol. 204, 26-35 (2017). HPTLC of quercitrin (1), isoquercitrin (2), quercitrin-3-O-β-D-xylopyranosyl-α-L-rhamnopyranoside (3) on silica gel with ethyl acetate – formic acid – acetic acid – water 100:11:11:26. Detection by spraying with NEU`s reagent (diphenylborinic acid 2-aminoethylester, natural product reagent), followed by drying at 110 °C for 2 min. Quantitative determination by absorbance measurement at 265 nm. LOD and LOQ were 31 ng/zone and 75 ng/zone for (2). Recovery was between 99.8 and 101.1 % for (2). Intermediate precision was <2 % (n=3).
J. Chromatogr. Sci. 54 (7), 1090-1095 (2016). Comparison of the dynamics of peptidization of L-serine (L-Ser), an important proteinogenic amino acid which undergoes spontaneous oscillatory processes of chiral inversion and peptidization with D-Ser and DL-Ser (racemate). The main analytical techniques used in the experiment were TLC-densitometry, HPLC–evaporative light scattering detector and LC–MS. The results showed the differences in peptidization dynamics of the two Ser enantiomers (L and D) and of the racemic mixture thereof (DL) and showed that DL-Ser characterizes with the higher, and L- and D-Ser with the lower peptidization yields.
J. AOAC Int. 100, 414-421 (2017). HPTLC of two binary mixtures containing pyridoxine hydrochloride (1) with either cyclizine hydrochloride (2) or meclizine hydrochloride (3) on silica gel with dichloromethane – acetone – methanol 14:2:1. Quantitative determination by absorbance measurement at 220 nm. The hRF values for (1-3) were 7, 25 and 80, respectively. Linearity was in the range of 0.2-5 μg/zone for (1) and 0.2-4 μg/zone for (2) and (3). The LOD and LOQ were 60 and 190 ng/zone for (1), 50 and 170 ng/zone for (2) and 60 and 170 ng/zone for (3), respectively. The intermediate precision was <2 % (n=3). Average recovery rate was 99.9 % for (1) and (3) and 100.1 % for (2).
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.
