J. Planar Chromatogr. 2, 133-137 (1989). The ion-pairing characteristics of tetraalkylammonium salts and cetrimide and also of tricaprylmethylammonium chloride were studied. In eluents containing 50% methanol and 0.05 mol/L ion-pairing reagent, the Rf values of salicylic acid derivatives displayed the following sequence: tetrabutylammonium hydrogensulfate > cetrimid > tricaprylmethylammonium chloride. On reversed-phase layers, the pH had no effect on retention. With increasing concentration of methanol the retention of the compounds decreased. TLC on RP-8 and (HPTLC) silica with mixtures of water and organic solvents containing NaCl and Bitton-Robinson buffer. Detection under UV 254 and 366 nm.
Chimica Scripta 29, 51-55 (1989). TLC of 2,3-dideoxy-3-tetrabromophthalimido-D-pentose isomers on silica with benzene - ethyl acetate 9:1 and dichloromethane - methanol 49:1 or 9:1.
Biochemical Systematics and Ecology 17, 366 – 372 (1989). TLC of permethyl ethers of bioflavones on silica with toluene – pyridine – formic acid 100:20:7 or 100:10:5, on cellulose with butanol – 2N NH3 1:1. Identification by comparison of characteristic Rf values and by visualization under UV.
Planta Med. 56, 451-455 (1990). TLC and HPTLC of triterpene saponins of the oleanolic acid type on silica with chloroform – methanol – propanol – water 9:12:2:8, ethyl acetate – methanol – water 100:13.5:10 or 100:25:10. Detection of sapogenins by spraying with Komarowsky and with Godin reagents and of sugars with diphenylamine – phosphoric acid.
Chromatographia 29, 363-365 (1990). TLC of pure carotenoids and natural carotenoid mixtures on silica with mixtures of acetone or tertiary alcohols with petrol ether, and on C-18 silica with mixtures of petrol ether, acetonitrile and methanol. Detection by spraying with saturated methanolic silver nitrate solution. Descrimination of e-end groups in carotenoids by comparing the color change.
Dünnschichtchromatographischer Nachweis in Cutistad-Lösung. (Determination of clotrimazole in Cutistad solution by thin-layer chromatography.) Deutsche Apotheker Zeitung 130, 619 (1990). TLC on silica with xylene – ethanol – ether 9:1:1. Detection by spraying with Dragendorff’s reagent.
(Layer impregnated with ammonium molybdate for TLC of water contaminated with phenols.) Z. Wasser-Abwasser-Forsch. 23, 113-115 (1990). TLC of phenols on silica impregnated with 5% ammonium molybdate using toluene-acetone-chloroform 49:35:25 as mobile phase. Detection limit for qualitative determination 0.6-1 µg per spot and for semiquantitative determinations between 2 and 10 µg.
Microchim. J. 40, 208-215 (1989). TLC separation of low-molecular weight cholesteryl esters such as cholesteryl formate, cholesteryl acetate, cholesteryl propionate and cholesterol from their mixtures with e.g. hexane - chloroform - ether - methanol - acetic acid - 92:1.5:6:0.5:0.2. Detection by dipping in cupric acetate - phosphoric acid - water solution (30 g of cupric acetate in 80 mL phosphoric acid and diluted to 1 L with water), followed by heating at 130 °C for 5 min.
