J. Planar Chromatogr. 32, 59-60 (2019). TLC of p-phenylenediamine on silica gel with ethyl acetate - diethyl ether 1:1. Detection by spraying with aqueous alkaline solution of Folin’s reagent (0.5 % Folin’s reagent in 5 % sodium carbonate solution). The hRF value of p-phenylenediamine was 45. The LOD for p-phenylenediamine was approximately 3 μg by visual evaluation.
J. Planar Chromatogr. 32, 65-68 (2019). HPTLC of endosulfan in biological samples (pieces of stomach, intestine, liver, spleen, kidney, and lungs) on silica gel with hexane - acetone 4:1. Detection by spraying with a 10 % sodium hydroxide solution and then with diphenylamine reagent (2 g diphenylamine in 20 mL glacial acetic acid and 20 mL ethyl acetate), following by exposure to sunlight for 10 min. The hRF values of the endosulfan coordination complex (alpha and beta isomers) were 66 and 85. Zones were stable for 8 to 10 days.
J. Planar Chromatogr. 32, 7-12 (2019). HPTLC of (RS)-mexiletine on RP-18 plates impregnated with 0.03 mM bovine serum albumin as chiral additive with acetonitrile - dichloromethane - methanol 1:1:1. Detection by exposure to iodine vapors. Resolution was 2.3 for the HPTLC method and 1.9 using an HPLC method. The HPTLC analysis took nearly 7 min, whereas HPLC took nearly 265 min to get the results.
Biomed. Chromatogr. 21 (10), 1064-1068 (2007). Indirect chiral separation of penicillamine (3,3-dimethylcysteine) enantiomers after derivatization with Marfey's reagent (FDNP-Ala-NH2) and two of its structural variants, FDNP-Phe-NH2 and FDNP-Val-NH2, with phenol - water 3:1 and solvent combinations of acetonitrile and triethylamine phosphate buffer in normal and reversed-phase TLC, respectively. Also separation of the diastereomers on a reversed-phase HPLC column with gradient elution of acetonitrile and 0.01 m trifluoroacetic acid. Comparison of the results due to these three reagents. Successful application of the method for checking the enantiomeric impurity of l-penicillamine in d-penicillamine and to check the enantiomeric purity of pharmaceutical formulations of d-penicillamine.
J. Planar Chromatogr. 20, 423-427 (2007). TLC of 8 essential amino acids (L-lysine, L-valine, L-isoleucine, DL-threonine, L-methionine, L-leucine, DL-phenylalanine, DL-tryptophan) on silica gel with 17 mobile phases, of which the mixed aqueous surfactant solution Triton X-100 (0.001 mM) - sodium dodecyl sulfate, 0.081 mM - acetone 1:1:5 was identified as the best mobile phase for specific separation of lysine. Visualization by spraying with 0.3 % ninhydrin in acetone. Limit of detection was 0.5 µg/zone.
J. Chromatogr. A 1173 (1-2), 146-150 (2007). HPTLC of oenothein B and quercetin glucuronide in aqueous extract of Epilobii angustifolii herba on RP-18 W phase with 1) 25 % acetonitrile in water (with 50 mM H3PO4) over 80 mm for oenothein B, and 2) with acetonitrile over 40 mm for quercetin glucuronide. Quantification of oenothein B and quercetin glucuronide by densitometry at 270 and 350 nm, respectively. Linearity was between 1.14 and 2.28 µg/zone for oenothein B and 77 and 691 ng/zone for quercetin glucuronide. Aqueous extract of Epilobii angustifolii herba contained 152.46 ± 4.92 mg/g oenothein B and 22.07 ± 1.38 mg/g quercetin glucuronide.
J. Planar Chromatogr. 20, 353-359 (2007). TLC of 8 N,N-disubstituted-2-phenylacetamides on RP-18 with acetone, acetonitrile, tetrahydrofuran, dioxane, methanol, ethanol, 1-propanol, and 2-propanol as organic modifiers of aqueous mobile phases. The retention observed with different mobile-phase modifiers was correlated, and good correlation was obtained between lipophilicity measured chromatographically and biological activity predictors. Detection under UV light at 254 nm.
J. Planar Chromatogr. 20, 347-351 (2007). TLC of DTAB on soil, silica gel, alumina, and kieselguhr with fifteen mobile phases, such as aqueous solutions of ammonium sulfate and urea, with chamber saturation for 10 min. Detection by spraying with modified Dragendorff reagent. Among the systems studied the best system for selective separation of DTAB from multicomponent mixtures of other surfactants was kieselguhr - 0.1 M ammonium sulfate. Semi-quantitative determination by spot-area measurement.
