J. Planar Chromatogr. 32, 237-241 (2019). HPTLC of protocatechuic acid (1) and quercetin (2) in the fruits of Carissa carandas on silica gel with toluene - ethyl acetate - formic acid 6:3:1. Quantitative determination by absorbance measurement at 310 nm. The hRF values for (1) and (2) were 57 and 61, respectively. Linearity was between 100 and 600 ng/zone for (1) and (2). The intermediate precision was below 2 % (n=9). The LOD and LOQ were 33 and 100 ng/zone for (1) and 28 and 85 ng/zone for (2), respectivley. Recovery rate was between 96.9 and 99.8 % for (1) and 97.9 and 98.8 % for (2).
J. Planar Chromatogr. 32, 191-196 (2019). HPTLC of phenolic compounds in 11 dark beers, 25 light beers, 10 non-alcoholic beers and 4 malt beers on silica gel with ethyl acetate - formic acid - acetic acid - water 50:55:55:13. Detection by dipping into a (1) 0.5 % methanolic solution of 2-aminoethyl diphenylborinate (natural product reagent or Neu’s reagent), followed by dipping into a 5 % methanolic polyethylene glycol (PEG) 400 solution for enhancement and stabilization of the fluorescent zones, or (2) 0.2 % methanolic DPPH radical solution. Documentation under white light and UV 366 nm. Zones at hRF values of 8, 13, 36, 45, 52 and 85 had the most impact on the principal component (PC) analysis and were recognized as markers for discrimination between dark and non-alcoholic beers. HPTLC-ESI-HRMS/MS2 analysis allowed the identification of desdimethyl-octahydro-iso-cohumulone (hRF 85) and iso-n/ad-humulone (hRF 95) as the most active bands with radical scavenging property.
J. Planar Chromatogr. 32, 115-120 (2019). HPTLC of ellagic acid (1), gallic acid (2) and ferulic acid (3) in the leaves of Elaeagnus angustifolia on silica gel with toluene - ethyl formate - formic acid 5:6.6:1.5. Quantitative determination by absorbance measurement at 290 nm. The hRF values for (1) to (3) were 36, 47 and 69, respectively. Linearity was between 56-677 ng/zone for (1), 100-1207 ng/zone for (2) and 100-1205 ng/zone for (3). The intermediate precision was below 2 % (n=6). Recovery rate was 101.4 % for (1), 100.9 % for (2) and 100.2 % for (3).
J. Planar Chromatogr. 21, 205-208 (2008). TLC of phenol and its methyl derivatives on RP-2, RP-8, RP-18, cyano phase, and DIOL phase with methanol - water, ethanol - water, n-propanol - water, acetonitrile - water, and acetone - water in different volume proportions (1000, 955, 9010, 8515, 8020, 7525, 7030, and 6535), 0.1 M acetic acid and 0.1 M sodium acetate in 30 % methanol (pH 5.0), 0.1 M potassium dihydrogen phosphate in 30 % methanol (pH 7.0), and 1 M ammonia in 30 % methanol (pH 11.3) in a saturated chamber. Best results were achieved on RP-2 with 0.1 M acetic acid and 0.1 M sodium acetate in 30 % methanol, 0.1 M potassium dihydrogen phosphate in 30 % methanol, and 1 M ammonia in 30 % methanol. Detection by spraying with 2 % methanolic iron(III) chloride solution or with a solution of titanium tetrachloride in concentrated hydrochloric acid (20 %) followed by heating at 120 °C for 30 s or 2 min.
extracts on polar-bonded stationary phases. J. of Chromatogr. A 1218 (19), 2812-2819 (2011). Two-dimensional TLC of phenolic compounds (extracted from Polygonum hydropiper L. and Polygonum cuspidatum L.) on cyano phase with non-aqueous solvents in the first direction and aqueous solvents in the second direction. For the separation of standards the optimal chromatographic systems was determined based on the retention data collected in one-dimensional TLC experiments by plotting graphs of Rf vs. Rf dependencies.
J. AOAC Int. 97, 1274-1281 (2014). TLC fingerprint for the optimization of accelerated solvent extraction conditions for the isolation of total polyphenolic compounds from common thyme (Thymus vulgaris), on silica gel with ethyl acetate – formic acid – acetic acid – water 100111113. Detection by spraying with 10 % methanol solution of sulfuric acid, followed by heating at 110 °C for 20 min. Quantitative determination by absorbance measurement between 320 and 700 nm.
Sulfation of 6-gingerol by the human cytosolic sulfotransferases a systematic analysis. Planta Medica 82(3), 238-243 (2016). Pure 6-gingerol was submitted to sulfation either with purified human sulfatases (SULT1A1, SULT1A2, SULT1A3, SULT1B1, SULT1C2, SULT1C3, SULT1C4, SULT1E1, SULT2A1, SULT2B1a, SULT2B1b, SULT4A1, and SULT6B1) or with cytosol of human organs (lung, liver, small intestine, kidney), in presence of [35S]-marked 3’-phosphoadenosine 5’-phosphosulfate, and, after centrifugation (13000 rpm, 3 min), the supernatant was analyzed by TLC on silica gel with acetic acid – n-butanol 21. The plate was dried with a hair-drier. Detection by autoradiography on an X?ray film; the radioactive band corresponding to the [35S]-sulfated 6-gingerol (hRf 76) was cut out and eluted with 0.5 mL water into a glass vial for liquid scintillation counting. The strongest 6-gingerol-sulfating activity was exhibited, among the enzymes tested, by SULT1A1 (followed by SULT1C4, SULT1A3, SULT1E1, SULT1A2 and SULT1B1, the other sulfatases being inactive), and, among the organ cytosols, by the small intestine (followed by liver, lung and kidney). The same procedure was applied to detect, after spin filtration, the same [35S]-sulfated 6-gingerol produced from 6-glycerol and [35S]-sulfate in presence of plate-cultured human cells HepG2 (hepatoma) and Caco-2 (colon adenocarcinoma); the amount of the produced sulfated form clearly depended on the gingerol concentration.
J. Liq. Chromatogr. Relat. Technol. 39, 698-701 (2016). HPTLC of resveratrol and saponins in syrup, powdered trunk, and bark samples of Yucca schidigera on silica gel with chloroform - methanol - water 35141. Detection by spraying with 10 % sulfuric acid - ethanol solution followed by heating at 100 ºC. Qualitative identification at 254 nm. The hRF values for phenols were >38, where these were <38 for saponins.
