Planta med. 66, 403-407 (2000). Preparative TLC of machilusol A, B, C, D, E, and F on silica gel with n-hexane - acetone 1:1, dichloromethane - acetone 10:1 and dichloromethane - ethyl acetate 10:1. Visualization by spraying with cerous sulfate solution, detection by heating.
J. Chromatogr. A 1077 (2), 188-194 (2005). HPTLC of (+)-catechin (C), (-)-epicatechin (EC), (-)-gallocatechin (GC), (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECg), (-)-epigallocatechin gallate (EGCg), procyanidin B1, and procyanidin B2 on cellulose prewashed with water (not necessary, when water was used as developing solvent) and dried with a hair dryer, with 1) water; 2) 1-propanol - water 1:4; 3) 1-propanol - water - acetic acid 4:2:1; 4) 1-propanol - water - acetic acid 2:8:1 in horizontal developing chamber (sandwich configuration). Detection with vanillin - H3PO4 reagent. Water enabled the separation of epimers C from EC and GC from EGC, as well as the dimers procyanidin B1 and B2. Additionally C, EGC, B1 and B2 were separated from all the other compounds. The best separation of the five main catechins (EC, GC, EGC, ECg, EGCg) present in green tea extract was achieved using 1-propanol - water - acetic acid 2:8:1. The chromatograms of oak bark extract developed in solvents with higher water content (1-propanol - water 1:4 and 1-propanol - water - acetic acid 2:8:1) showed less bands than chromatograms developed in solvents with higher organic modifier content (e.g. 1-propanol - water - acetic acid 4:2:1). It was proved that such behavior was due to the presence of procyanidins beside the main component catechin.
Phytochemistry 21, 2581-2583 (1982). TLC of highly methylated flavone aglycones on silica or polyamide with toluene - ethyl acetate - formic acid 58:33:9, benzene - pyridine - formic acid 72:18:10, chloroform -methanol 90:10 or benzene - MEK - methanol 4:3:3. Detection by UV/NH3 or with Naturstoffreagenz-A in methanol. Isolation of flavonoids from crude extracts by PLC.
J. Chromatogr. 318, 450-454 (1985). TLC of anthocyan aglycones, monoglycosides, diglycosides and triglycosides on cellulose with conc. HCl - formic acid water 30.5:7.7:61.5; 30.8:27.8:41.4; 24.9:23.7:51.4 and 7 other solvents. Rf values of 27 compounds in 11 solvent systems are listed. The solvent composition 24.9:23.7:51.4 has the advantages of resolving, within a reasonable Rf range, aglycones, monoglycosides and diglycosides.
J. Chromatogr. 511, 396-401 (1990). HPTLC of natural phenolic compounds with the AMD system on silica using a 20-step gradient based on methanol – dichloromethane – water – formic acid. Detection under UV 360 nm for coumarins and phenol carboxylic acids, and by dipping in a 4% aqueous aluminium sulfate solution for flavonoids. Densitometry at 360 nm.
Phytochemistry 33, 171-174 (1993). TLC of various phenolic plant constituents on silica with toluene - acetone - formic acid 30:30:6. Detection with 1% vanillin - hydrochloric acid reagent. Sugar analysis after hydrolysis on silica with chloroform - methanol - water 64:36:2. Detection with thymol - sulfuric acid reagent. TLC conditions suitable for various types of plant polyphenols.
J. Planar Chromatogr. 17, 207-212 (2004). HPTLC of malvidin 3-glucoside, cyanidin 3-glucoside, delphinidin 3-glucoside, peonidin 3-glucoside,and petunidin 3-glucoside on silica gel with ethyl acetate - formic acid - twice distilled water 17:2:3 in an unsaturated twin trough chamber. After drying detection with methanolic 2,2-diphenyl-1-picrylhydrazyl reagent. Quantitative determination by videodensitometry.
J. Planar Chromatogr. 23, 230-232 (2010). HPTLC of (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, (-)-epigallocatechin gallate, (-)-epicatechin gallate, procyanidin B2, procyanidin A2, and methylxanthines (theobromine and caffein) on cellulose with n-propanol - water - acetic acid 20:80:1 in a horizontal chamber. Detection by dipping for 1 s into 4-dimethylaminocinnamaldehyde detection reagent. Quantitative determination by absorbance measurement at 655 nm. By densitometry LOD for (-)-epicatechin and procyanidin B2 was 0.2 and 2 ng/zone, respectively; LOQ was 0.4 ng and 4 ng/zone, respectively. These limits were lower by a factor 50 for (-)-epicatechin and by a factor of 10 for procyanidin B2 than those obtained by HPLC. The TLC method gave a more accurate result for the (-)-epicatechin content of baking chocolate than the HPLC method which was also more time-consuming.
