European Journal of Medicinal Chemistry 45, 3719-3725 (2010). TLC of sulpiride and mebeverine hydrochloride on silica gel with absolute ethanol - methylene chloride - triethylamine 35:15:1. Quantitative determination by absorbance measurement at 221 nm. The method was linear in the range of 0.4-1.4 µg/band for sulpiride and 0.2-1.6 µg/band for mebeverine hydrochloride. The recovery was 100.4-101.0 %. The hRf value of sulpiride was 42 and of mebeverine hydrochloride 62. The results obtained by this TLC method were comparable with those by HPLC.
Planta Medica 83(01/02), 143-150 (2017). Preparative TLC on silica gel H to purify amide alkaloids from column chromatography apolar subfractions of aerial part methanolic extracts of: a) Piper flaviflorum: decenoylpiperidide (petroleum ether – acetone 10:1), N-methoxycinnamoyl-pyrrolidine, dihydropiperyline, stigmalactam, chingchengenamide A (petroleum ether – ethyl acetate 8:1); and b) P. sarmentosum: methylenedioxyphenyl-undecadienoyl/undecatrienoyl-pyrrolidine (petroleum ether – acetone 1:2), cinnamoyl-hydroxypyrrolidine and deacetylsarmentamide B (chloroform – methanol 9:1); detection with Dragendorffʼs reagent.
Chinese J. Chem. Reag. (Huaxue Shiji) 14, 15-16, 28 (1992). TLC of 3-cyanopyridine, nicotinamide and nicotinic acid on silica with benzene - chloroform - methanol - ethylenediamine - water 3:4:1:1:1. Quantification by densitometry at 365 nm.
J. Planar Chromatogr. 11, 342-345 (1998). HPTLC of N-hydroxyethylamides of aryloxyalkylene and pyridine carboxylic acids on RP-8 with methanol - water mixtures with methanol concentrations from 90% to 60% in increments of 5%. Visualization and densitometry under UV 254 nm.
J. AOAC Int. 92, 725-729 (2009). HPTLC of acrylamide extracted from coffee samples on silica gel with ethyl acetate - tert. butyl methyl ether 4:1 in a twin trough chamber or automatic developing chamber. Pre-chromatographic in situ derivatization of the extracts (applied as area) by overspraying with dansulfinic acid produced the fluorescent dansylpropanamide band. Quantitative determination by fluorescence measurement at 254/>400 nm. The limit of quantification was 48 µg/kg. The linearity over the whole procedure showed determination coefficients between 0.9995 and 0.9825 (n = 6). The within-run precision (%RSD, n = 6) of the chromatographic method was 3%. Commercial coffee samples analyzed showed acrylamide contents between 52 and 191 µg/kg, which was in correlation with amounts reported in publications.
J. Planar Chromatogr. 24, 435-440 (2011). TLC of nine N-cyclohexyl-N-substituted-2-phenylacetamides on RP-18 with different aqueous eluents; water - acetone, water - acetonitrile, and water - dioxane. The volume fraction of the organic modifier in the aqueous mobile phase comprised 60-80 % (dioxane, acetone) and 70-90 % (acetonitrile) and varied in steps of 5 %. Detection under UV light at 254 nm. The effects on retention behavior of all investigated modifiers were similar. The linear relationship between retention parameters and organic modifier content allowed the extrapolation procedure. The result of the investigation showed that reversed-phase RM0 proved to express the lipophilic nature of an investigated compound as well as its biological activity.
Planta Med. 83, 1097-1102 (2017). The fractionations on a silica gel column (with a gradient of ethyl acetate, methanol and petroleum ether/dichloromethane) of the dichloromethane and methanol extracts of Antidesma ghaesembilla bark were monitored by TLC on silica gel with chloroform – methanol – water – formic acid 290:20:1:1 or 290:50:1:1, respectively. From fractions of the dichloromethane extract, chavibetol, sitostenone, asperphenamate, daucosterol, 5,7-dimethoxy-aristolochic acid II and 10-amino-5,7-dimethoxy-aristolic acid II were later isolated, the last one was detected by Dragendorff reagent. From fractions of the methanol extract, glucosides of aristolic acid and of vanillic acid were isolated and separated by preparative TLC with chloroform – methanol – acetone – formic acid 450:75:25:2. This preparative TLC yielded protocatechuic acid (hRF 51) and a mixture (hRF 14–19), from which a methyl-phloroglucinol glucoside was isolated by gel exclusion chromatography.
J. Liquid Chromatogr. 15, 1621-1638 (1992). TLC and HPTLC of title substances on silica with different solvent compositions. Detection by spraying with orcinol ferric chloride reagent, by densitometry at 550 nm, and immunostaining.
