J. Planar Chromatogr. 28, 251-255 (2015). HPTLC of rivastigmine on silica gel with toluene - acetonitrile - formic acid 6:3:1. Quantitative determination by absorbance measurement at 540 nm. The hRF value for rivastigmine was 41. Linearity was in the range of 125-1250 ng/zone. LOD and LOQ were 22 and 66 ng/zone, respectively. The intermediate precision was below 8 % (n=3). Recovery ranged between 99 and 102 %.

J. Ethnopharmacol. 174, 178-186 (2015). HPTLC of magnolol (1) and honokiol (2) in the cortex of Magnolia officinalis and aristolochic acid I (3) and II (4) in the radix of Aristolochia baetica on silica gel with methanol - ethyl acetate - toluene 1:2:30 for (1) and formic acid - water - ethyl acetate - toluene 1:1:10:20 for (2). Detection of (1) and (2) by spraying with vanillin reagent, followed by heating at 110 °C for 5 min. Detection of (3) and (4) by spraying with stannous chloride 100 g/L in diluted hydrochloric acid, followed by heating at 100 °C for 1 min. Identification under UV light at 365 nm for (3) and (4). The hRF values for (1) to (4) were 40, 50, 46 and 54, respectively.

J. Food Comp. Anal. 44, 45-55 (2015). HPTLC of gangliosides based on the degree of sialylation in the milk fat globule membrane of whole milk on silica gel with chloroform - methanol - 28 % ammonia - water 60:35:7:3. Bands containing gangliosides were excised and glangliosides extracted for LC-MS analysis.

Rev. Bras. Farmacogn. 26, 1-14 (2016). HPTLC fingerprinting of three varieties of Marantodes pumilum on silica gel with chloroform - methanol 9:1. Detection by dipping into a mixture of p-anisaldehyde and sulfuric acid reagent, followed by heating at 100 ºC for 10 min. Qualitative evaluation under UV light at 254 and 366 nm. M. pumilum var. pumila leaves differ from the other two varieties based on the presence of an orange band at hRF 22 or 56. The stem extract of M. pumilum var. alata had the least intense orange band at either hRF 22 or 56. A peak at hRf 22 appeared as a major compound of the stem of M. pumilum varieties in the order of var. lanceolata > var. pumila > var. alata, and can be used for quality control and identification of different parts of the plant materials.

J. Liq. Chromatogr. Relat. Technol. 39, 549-557 (2016). Review of the use of TLC and HPTLC for the analysis of inks in forensic applications, including sample preparation, layers, sample application, detection, documentation and results interpretation. The author also described the application of TLC in food dye analysis as well as future trends in the field.

J. Planar Chromatogr. 29, 299-305 (2016). Analysis of the antioxidants ascorbic acid (1), gallic acid (2), caffeic acid (3), quercetin (4), and biogenic amines (–)-epinephrine (5), (–)-norepinephrine (6), isoprenaline hydrochloride (7), dopamine hydrochloride (8), 3,4-dihydroxy-d-phenyl-alanine (d-dopa) (9), and 3′,4′-dihydroxy-2-(methylamino)acetophenone hydrochloride (adrenalone) (10) applied as individual zones in different concentrations on silica gel, without development. Radical-scavenging activity was measured by spraying with 0.03 % 2,2-diphenyl-1-picrylhydrazyl (DPPH radical reagent) solution in methanol and stored in dark at 22 °C for 5 min, followed by scanning in a dark place. Image data was converted into chromatograms, from which the spot area as a function of the reaction time was monitored. The title "Chromatographic approach" is misleading, as there is no chromatography.

J. Ethnopharmacol. 182, 150-159 (2016). HPTLC of 3,5,7,3′,4′-pentahydroxy flavone in the leaves of Madhuca indica on silica gel with acetone – n-hexane 1:3. The hRF value for the active compound with potent antiulcer activity was 40.

Biochem. Biophys. Res. Commun. 470, 168-174 (2016). HPTLC of glycosphingolipid during the evaluation of enzyme activities of human Gb3/CD77 synthase supplemented with UDP-[14C]Gal on silica gel with chloroform – methanol – water 11:9:2. Detection of radiolabeled reaction products by exposure to phosphor screens for 8 weeks in -80 °C, followed by scanning. In parallel staining was used to facilitate identification of bands on the phosphor screens by spraying the plates with orcinol (0.2 %) in 3 M aqueous sulfuric acid, followed by heating at 110 °C for 10 min.
