J. Planar Chromatogr. 30, 502-509 (2017). HPTLC of chlorogenic acid (1), gallic acid (2), caffeic acid (3), quercetin (4), p-coumaric acid (5) and kaempferol (6) in the fresh leaves, flowers, pods, and dried pods and seeds of M. oleifera on silica gel with toluene – ethyl acetate – formic acid 14:10:1. Quantitative determination by absorbance measurement at 282 nm. The hRF values for (1) to (6) were 1, 31, 41, 45, 49 and 52, respectively. Linearity was between 0.1 and 1.5 μg/zone for (1) to (6). LOD and LOQ were 142 and 382 ng/μL for (1), 126 and 343 ng/μL for (2), 114 and 410 ng/μL for (3), 116 and 301 ng/μL for (4), 125 and 356 ng/μL for (5) and 110 and 345 ng/μL for (6), respectively. The intermediate precision was <3 % (n=6). Average recovery was 96.2 % for (1), 97.9 % for (2), 97.3 % for (3), 96.5 % for (4), 97.1 % for (5) and 96.2 % for (6).
and Glycyrrhiza uralensis Fisch.) by HPTLC, validated by HPLC and DNA sequencing. J. Planar Chromatogr. 30, 467-473 (2017). HPTLC of 18-β-glycyrrhizic acid in two licorice root species (Glycyrrhiza glabra L. and Glycyrrhiza uralensis Fisch) on silica gel with dichloromethane – methanol – water – formic acid 120:75:15:1 with chamber saturation for 20 min to a migration distance of 70 mm. Quantitative determination by absorbance measurement at 254 nm. Detection of species by immersion into sulfuric acid reagent, followed by heating at 100 °C for 10 min, evaluation under UV 366 nm and white light. The HPTLC results correlate with the data obtained by HPLC and by DNA sequencing.
J Herpetol 51(4), 538-551 (2017). HPTLC of retinyl palmitate (1), retinal (2), and of retinal oxime with all trans, syn (3) and anti (4) isomers, on silica gel with cyclohexane – toluene – ethyl acetate 5:3:2 in a twin-trough chamber. Evaluation under white light and at UV 254 nm and after spraying with Carr–Price reagent (saturated solution of SbCl3 in chloroform). The hRF values of (1), (2), (3), and (4) were 84, 55, 44, and 24, respectively.
Hoffm. A review. J. Ethnopharmacol. 220, 294-320 (2018). Review of the phyto-constituents of Arctotis arctotoides, including the application of TLC and HPTLC for the analysis of steroids and acids, alcohol and phenolics, guaianolides, germacranolide, eudesmanolides, farnesol derivatives and sesquiterpenes. The review also described bio-autographic methods on TLC plates against Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Escherichia coli and Shigella sonnei) bacteria.
J. Planar Chromatogr. 31, 155-162 (2018). HPTLC of lawsone in Lawsonia inermis on silica gel with benzene ‒ ethyl acetate ‒ acetic acid 75:25:1. Quantitative determination by absorbance measurement at 275 nm. The hRf value for lawsone was 33. Linearity was in the range of 50-350 ng/zone. The intermediate precision was below 2 % (n=6). The LOD and LOQ were 16 and 50 ng/zone for lawsone, respectively. Average recovery was 96 %.
inhibits ceramide glucosyltransferase activity
Biochem. Biophys. Res. Commun. 491, 265-270 (2018). HPTLC of nitrobenzoxadiazole (NBD)-labeled lipids in the reaction mixture of ceramide glucosyltransferase (GlcT-1) on silica gel with chloroform – methanol – water 65:25:4. NBD-labeled lipids were visualized by UV-B illumination. The amount of C6-NBD-glucosylceramide (GlcCer) generated was quantified by TLC image processing. The method was used to study the effects of JAK/STAT3 pathway inhibitors on GlcT-1 activity.
J. Agric. Food Chem. 65, 8773-8778 (2017). HPTLC of aflatoxin B1 on silica gel with chloroform – ethyl acetate 4:1. Quantitative determination by fluorescence measurement at 366/>400 nm.
Trends Anal. Chem. 112, 87-101 (2019). Review of high-resolution mass spectrometry (HRMS)-based techniques and their application in the analysis of secondary metabolites covering papers published between 2015 and 2018. The benefits of HPTLC-hyphenations in the discovery and characterization of active natural compounds were also discussed, including Orbitrap MS-coupled methods and the use of TLC in combination with stand-alone HRMS instruments.
