Anal. Biochem. 192, 219-221 (1991). TLC of D- and L-lactic acid enantiomers on Cu(II)-impregnated silica with dioxane - water 9:1. Confirmation of the separation by enzymatic tests. The separation is suitable for radiochemical measurements. The method is useful for rapid control of the radiochemical stability of both D- and L-forms of lactic acid.
J. Planar Chromatogr. 6, 278-281 (1993). TLC of 14 phenolic acids on cellulose, "face down" in a DS horizontal chamber with mixtures of methanol, acetonitrile, benzene, and acetic acid in the first direction, sodium formate - formic acid - water 10:1:200 in the second direction. Detection under UV 366 nm before and after treatment with NH3 vapor, and spraying with diazotized selfanilic acid in 10% sodium carbonate solution, diazotized p-nitroaniline in 10% sodium carbonate solution, or with a 2% solution of ferric chloride.
J. Planar Chromatogr. 8, 148-151 (1995). Description of the evaluation of 18 new visualizing agents for the detection of aromatic amines on a) silica, b) a mixture of silica and kieselguhr G with benzene - methanol - acetic acid 45:8:4, and c) polyamide with acetone - ethanol 4:1. For the separation on a) the best visualization results were obtained with bromocresol green, bromothymol blue, sodium hydroxide, thymol blue, and methyl red; for the separation on b) best results were obtained with thymolphthalein. The visualization effects on c) were not as good as on a) and b). The utility of any particular visualizing agent depends on the type of chromatographic support used. The composition and handling of the visualization reagents are given.
Dünnschicht-Chromatographie InCom Sonderband 1996,196-201. TLC and HPTLC of lauric, myristic, palmitic, and stearic acid on silica with hexane - acetone 4:1; visualizing agents were bromothymol blue, thymol blue, phenol red, helasol green, bromocresol green, brilliant-cresyl blue, bromophenol blue (as 50 mg/100 ml solution in 2 % aqueous sodium hydroxide solution) and neutral red, aniline blue, alkaline blue, brilliant green (as 50 mg/100 ml solution in water. Evaluation 15 min after spraying (I), followed by heating at 110 °C for 10 min (II). The best detection limits were obtained with aniline blue and alkaline blue.
Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 18, 390-393 (1998). TLC of the methyl esterification products on silica with petroleum ether - ether- acetic acid 35:15:1. Detection by exposure to iodine vapor. Evaluation of the completeness of esterification by finger print techniques. Quantitation by GC.
J. Chinese Trad. & Herb. Drugs (Zhongcaoyao) 32 (5), 404-407 (2001). TLC on cellulose layer with ethyl acetate - pyridine - acetic acid - water 5:5:1:3, before and after hydrolysis of uronic acid containing polysaccharides. Detection under UV and by spraying with aniline-O-phthalic acid reagent. Discussion of the advantages of the method compared to conventional TLC procedures.
J. Agric. Food Chem. 49, 2-8 (2001). TLC of plant extracts, caffeic and rosmarinic acid on silica gel with chloroform - ethyl acetate - formic acid 5:4:1 and ethyl acetate - methanol -water 77:13:10. Visualization by spraying with iron(III)chloride (2% in ethanol) and aluminium chloride (1% in ethanol).
II. Comparison of separation of fatty acids on RP-18 plates with different mobile phases. J. Liq. Chrom. & Rel. Technol. 26, 2663-2671 (2003). TLC of fatty acids (octa-, nona-, deca-, undeca-, dodeca-, trideca-, tetradeca-, pentadeca-, hexadeca-, heptadeca-, and octadecanoic acid) on RP-18 (with and without concentrating zones). Visualization by exposure to iodine vapor. The best separation of the acids investigated was obtained on RP-18 with a concentrating zone, and methanol - water 19:1.
