Trends Anal. Chem. 78, 84-94 (2016). Review on clean-up and recent advances in analysis of biogenic amines (BAs) in human body and dairy products of foodstuffs. TLC coupled with mass espectrometry was described as a common analytical technique used for analysis of BAs. Commonly used derivatizing reagents for chromatographic analysis of BAs were also described.
J. Chromatogr. 435, 256-257 (1988). TLC on sodium nitrite-impregnated silica with benzene - ethyl acetate 20:1. Detection by spraying with 2% sulfanilic acid in concentrated hydrochloric acid.
Planar Chromatogr. 4, 316-318 (1991). Separation of selected isomers by RPTLC and investigation of the dependence of Rf and RM values on the numerical values of topological indexes. TLC of a- and ß-naphthol and a- and ß-naphtylamine on Kieselguhr G impregnated with a 15% solution of paraffin oil in benzene; development with methanol - water 1:9, detection under UV 254 nm.
Kautschuk + Gummi - Kunstoffe 41 (9) 875-881 (1988). TLC of antioxidants IPPD (N-isopropyl-N'-phenyl-p-phenylene-diamine), 6PPD (N-1,3-dimethyl-butyl-N'-phenyl-diamine), N,N'-diaryl-PPD (N,N'-diaryl-p-phenylene-diamine) and TMQ (2,2,3-trimethyl-1,2-dihydroquinoline) on silica with chloroform - hexane - methanol - acetic acid 15:6:1:1. To remove plasticizers the TLC plate is chromatographed twice with petrol ether first. Detection by multi-wavelength scanning of UV absorbance at 240, 280, 320, 360 nm and visually by spraying with 3% ethanolic solution of 2,6-dichloroquinone-4-chlorimide. Additionally identification by recording of UV spectra. A further mobile phase system (toluene - hexane - methanol 29:15:6) is mentioned.
Separation of DNA fragments on composite agarose - linear polymer matrices. J. Chromatogr. A 871, 289-298 (2000). Study of the effect of hydrophilic linear polymer additives on the migration behavior of double stranded DMA molecules, ranging from 200-1000 base pairs in ultra-thin-layer agarose electrophoresis. Among the various polymers investigated, addition of linear polyacrylamide resulted in the best separation performance. The separation mechanism using composite matrices was discussed and the activation energy curves were plotted based on the slopes of the Arrhenius plots of the various composite matrices.
CBS 95, 2-4 (2005). TLC of seven biogenic amines (extracted with trichloroacetic acid from fish, followed by dansylation with dansyl chloride) on silica gel (prewashed with developing solvent) with benzene - chloroform - triethylamine 10:6:7 or 10:6:2 in horizontal developing chamber over 90 mm. Quantitative determination by fluorescence measurement at 365 nm/> 400 nm. Calibration using peak area, LOD 7.5 mg/kg, LOQ 56 mg/kg.
Chromatographia 37, 133-143 (1993). TLC method for the determination of catecholamines in human urine. Separation on NH2-modified silica, followed by in-situ visualization by heating. Discussion of possibilities to use this derivatization technique for other urine components, such as creatine, creatinine, uric acid and glucose.
International Journal of ChemTech Research 2(1), 646-652 (2010). TLC on silica gel with toluene - methanol - triethylamine 9:3:1 with chamber saturation for 30 min. The hRf value was 71. Densitometric evaluation at 282 nm. The method was linear in the range of 100-2000 ng/band with r2 = 0.9973. The repeatability of sample application and measurement of peak area (%RSD, n=6) was 0.461 % and 0.363 %. The %RSD for intra-day and inter-day variation was 0.752-0.961 % and 0.848-1.082 % respectively. The LOD and LOQ was 10 and 50 ng/zone, respectively. The average recovery was 99.5 %. The samples were subjected to stress conditions (acid, base, oxidative, thermal) and all degradation products were well resolved from the main compound. The method was found suitable for stability studies and for routine analysis of the drug in biological fluids.
