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. 22, 97-100 (2009). TLC of (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, (-)-epicatechin gallate, (-)-epigallocatechin gallate, theaflavin, theaflavin 3-gallate, theaflavin 3’-gallate, and theaflavin 3,3’-digallate on polyamide phase in a horizontal chamber (saturated for 15 min) by twofold development with chloroform - methanol 2:3 or n-butanol - acetone - acetic acid 5:5:3. Separation of the flavonols myricetin, quercetin, kaempferol, rutin and the phenolic acids gallic acid, chlorogenic acid, and caffeic acid was achieved by twofold development with chloroform - methanol 2:3. Detection by spraying with iron(III) chloride solution and evaluation under daylight. Quantitative determination by absorbance measurement at 600 nm.
J. Liq. Chromatogr. Relat. Technol. 37, 1644-1653 (2014). HPTLC fingerprinting of 12 commercially available fruit teas on silica gel with n-butanol - formic acid - water 12:3:4:5. Detection by heating at 100 °C for 3 min, followed by dipping into NP reagent (1 g of diphenylborinic acid aminoethylester dissolved in 200 mL of ethyl acetate) followed by dipping into PEG reagent (10 g of polyethylene glycol 400 in 200 mL of dichloromethane). Quantitative determination by absorbance measurement at 366 nm. A principal component analysis allowed to distinguish between red fruit teas based on the chromatographic profile.
Journal of Ethnopharmacology 163, 192-202 (2015). TLC of the aqueous extract (crude vs. after tannin removal on a polyamide column) of the kino (red hydrosoluble exudate) of Pterocarpus erinaceus on silica gel with s-butanol – water – acetic acid 14:5:5. Detection with vanillin-hydrochloric acid reagent revealed catechic tannins and related polyphenols as dark pink zones. These compounds showed hRfs between 0 and 40, and above 60 in the case of the crude extract, whereas they almost did not appear in the tannin-free fraction. The extracts were also submitted to HPLC-HRMS, allowing the identification of epicatechin monomer in both extracts and of oligomers in the crude extract only.
J. AOAC Int. 99, 374-379 (2016). HPTLC of glabridin in the roots of Glycyrrhiza glabra on silica gel with hexane – ethyl acetate – chloroform 5:4:3. Quantitative determination by absorbance measurement at 285 nm. The hRF value of glabridin was 48. Linearity was in the range of 50-500 ng/zone. The LOD and LOQ were 10 ng/zone and 30 ng/zone, respectively. Intermediate precisions were below 2 %. Recovery was between 100.6 and 102.0 %. Compared to a validated HPLC method there was no statistically significant difference in the mean values.
