Chemosphere. 81, 299-305 (2010). HPTLC of eleven mono- and poly-substituted phenolic
compounds on RP-18 with methanol - water (with increasing methanol content from 40-70 %) (1), acetonitrile - water (40-70 %) (2), and acetone - water (45-75 %) (3) and on cyano phase with methanol - water (30-60 %) (4) and acetonitrile - water (30-55 %) (5). In all instances, the content of organic modifier was increased in steps of 5 %. Detection under UV light at 254 nm. Chromatographic descriptors were statistically established to determine the soil–water partition coefficient for the compounds.
J. Liq. Chromatogr. Relat. Technol. 43, 925-933 (2020). HPTLC of 21 cycloalkylspiro-5-hydantoins on RP-18 with mixtures of water and organic solvent (acetone: 0.5-0.8 v/v, 1,4-dioxane: 0.5-0.74 v/v, tetrahydrofuran: 0.4-0.7 v/v, acetonitrile: 0.5-0.7 v/v). Detection at UV 254 nm. The logarithm of partition coefficient, log P, for the investigated compounds was calculated. Multivariate data analysis (hierarchical cluster analysis (HCA) and principal component analysis (PCA) was performed.
J. Liq. Chromatogr. Relat. Technol. 43, 852-862 (2020). HPTLC of diphenylacetamide derivatives on RP-18 with binary mixtures of organic modifier (ethanol, n-propanol, tetrahydrofuran and acetonitrile 36–52 % with 4 % increments). Detection at UV 254 nm. Lipophilicity of examined derivatives was determined. Two multivariate methods, Cluster Analysis, (CA) and Principal Component Analysis, (PCA) were performed to study the compliance of the chromatographic parameters, the standard measure of lipophilicity, the pharmacokinetic predictors and the toxicity parameters of the substances.
J. Liq. Chromatogr. Relat. Technol. 43, 580-588 (2020). Retardation factor (hRF) of 42 amino acids in two different eluents (acetonitrile - sodium azide and 1,2 dioxane-sodium azide solutions) were predicted by different quantitative structure-retention relationship (QSRR) methods. The method analyzed the effect of sum of geometrical distances between N and O in separation of amino acids in RP-TLC.
J. Planar Chromatogr. 33, 245-253 (2020). HPTLC of twenty-one chalcones on RP-18 with three binary combinations (acetonitrile - water, ethanol - water and acetone - water) in the following compositions: 1:1, 3:2, 7:3 and 4:1. Detection at UV 254 nm. Acetonitrile - water was found to be the most suitable system for lipophilicity prediction of tested compounds using calculated logP values. Quantitative structure-retention relationship (QSRR) analysis was performed to identify the most important structural and physico-chemical properties that influence retention behavior of tested compounds.
J. Liq. Chromatogr. Relat. Technol. 43, 328-335 (2020). HPTLC of verapamil, diltiazem, ivabradine, and its related analogs on silica gel with acetonitrile - methanol (acidified with 25 % formic acid) with the following volume fraction of methanol: 0.25, 0.20, 0.15, 0.13 and 0.10. Detection under UV 254 nm. Retention behavior was investigated and quantitative structure retention relationship (QSRR) modeling was performed with the use of the stepwise multiple linear regression.
Planta Medica 84(6/7), 465-474 (2018). The new concept “Comprehensive HPTLC Fingerprinting” was applied to define specifications for the identification and purity assessment of Angelica gigas roots, and for the quantification of its markers: the coumarins decursin and decursinol angelate. Methanolic root extracts of A. gigas (10 reference materials, 24 commercial samples), of 26 other Apiaceae species (including 10 Angelica, 9 Ligusticum, 2 Notopterygium, 4 Peucedanum, and Levisticum officinale) and of mixtures, were developed with toluene - ethyl acetate - acetic acid 90:10:1 on HPTLC silica gel (at 33% relative humidity, chamber pre-saturated for 20 min with filter paper and developing solvent) and dried for 5 min. Detection under white and UV lights before and after derivatization by dipping into 10% sulfuric acid in methanol and then heating 3 min at 100°C. Quantitative evaluation by densitometry in fluorescence mode at UV 313 nm, and luminance was also calculated from the image pixels. The study showed the presence in A. gigas of nodakenin, decursinol, 7-demethylsuberosin, imperatorin, osthole, and isoimperatorin at hRF 0, 4, 15, 33, 38 and 44 respectively. Z-ligustilide (hRF 59) was absent from A. gigas, allowing 1) to distinguish it from several other Apiaceae species; 2) to identify in mixtures with A. gigas two common adulterants (A. acutiloba, A. sinensis) even at 1% in the root powder. Minimal content of A. gigas fingerprint markers (decursin + decursinol acetate, co-eluting at hRF 27) was assessed as 3% (w/w) based on the quantified peaks from A. gigas reference materials.
J. Liq. Chromatogr. Relat. Technol. 42, 563-569 (2019). TLC of 17 new anti-proliferative and antiinflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines on RP-18 with acetone - aqueous TRIS (tris(hydroxymethyl)-aminomethane) buffer pH 7.4 (ionic strength 0.2 M), where the concentration of acetone was from 50 to 85 % in 5 % increments. Lipophilicity parameters were determined (RM0 and logPTLC) and compared with computationally calculated lipophilic parameters. Relation of lipophilicity with predicted and experimental biological activities was discussed.
