J. Planar Chromatogr. 3, 435-436 (1990). Review of TLC separation of phenols with 21 references. Reported is the separation of 11 phenols on silica resp. a mixture of silica and 10 or 15% sodium phosphotungstate in the presence of 3% agar-agar - polyvinyl alcohol 1:2 with benzene - diethylamine 4:1. Visualization by spraying with a fresh aqueous solution of 1.25% Kodak CD-3 - 2.5% Na2CO3 1:1. Detection limit 10-2 µg/spot; the method can also be applied to quantitative in situ analysis.
J. Chromatogr. 590, 369-372 (1992). OPLC of phenolic dialdehydes on silica with ether - hexane - chloroform 12:8:1. Detection by refractometry. Purification of two isomeric dialdehydes.
Biochemical Systematics and Ecology 23, 79-87 (1995). TLC of caffeic acid, flavonoids, styrylpyrones on cellulose with phosphoric acid - water mixtures. Visualization by spraying with diphenyl boric acid - ethanol amine complex (1%) in methanol.
1. Initiation of authenticity profiles. J. Agric. Food Chem. 45, 1752 -1757 (1997). Preparative TLC of vanillin on silica with dichloromethane - ethanol 19:1. Detection under UV 254 nm.
Z. Lebensm. Unters. Forsch. 206, 99-102 (1998). TLC of phenolic compounds on silica gel with a mixture of chloroform - methanol - water 63:35:10. Visualization by spraying with a solution of ferric chloride and potassium ferricyanide. Compounds with antioxidative activity were visualized after spraying with a solution of b-carotene and linoleic acid and observing the delay in bleaching of the b-carotene.
J. Agric. Food Chem. 49, 3725-3727 (2001). TLC of vanillin on silica gel with hexane - acetone 2:1 and chloroform - methanol 9:1. Visualization by spraying with 2,4-dinitrophenylhydrazine (0.4% solution in 2 N HCl) and o-dianisidien in acetic acid.
J. Planar Chromatogr. 19, 449-453 (2006). HPTLC of caffeic, p-coumaric, and ferulic acid on silica gel with dichloromethane - acetonitrile - 90 % formic acid 95:5:1. Quantitative determination by absorbance measurement at 320 nm. The method is precise and accurate.
f.) Etting. J. Planar Chromatogr. 23, 104-107 (2010). TLC of (+)-catechin, ellagic acid, quercetin, and ferulic acid on silica gel with toluene - ethyl acetate - fomic acid 6:4:1 in a twin-trough chamber previously saturated for 30 min at 25 °C. Other mobile phase compositions were ethyl acetate - methanol - water 10:1:1, n-butanol - acetic acid - water 4:1:5 (upper layer), n-butanol - ethanol - water 20:5:11, n-butanol - acetic acid - water 6:2:1, toluene - ethyl acetate - formic acid 5:5:1 and 7:3:1, and toluene - ethyl acetate - methanol - formic acid 140:60:1:1. Quantitative determination by absorbance measurement at 320 nm. Detection by dipping in anisaldehyde reagent, followed by drying and heating at 110 °C for 5 min. Characteristic bands of (+)-catechin, ellagic acid, quercetin, and ferulic acid were observed at hRf 35, 41, 63 and 66, respectively. Precision (CV, n = 7) was 0.39, 0.44, 0.55 and 0.16 % and repeatability (CV, n = 7) 0.65, 0.95, 0.37 and 0.18 %, respectively. LOD was 54, 340, 48 and 78 ng/band, and LOQ 4.1, 6.5, 1.6 and 1.5 µg/band, respectively. Linear regression was 0.9993 (100-500 ng/band), 0.9883 (1000-5000 ng/band), 0.9989 (100-500 ng/band) and 0.9987 (100-500 ng/band), respectively.
