J. Liq. Chromatogr. & Relat. Technol. 29, 2141-2151 (2006). HPTLC of flavonoids (with rutin, chlorogenic acid, hyperoside, and gallic acid as reference substances) on silica gel in a twin-trough chamber with ethyl formate - toluene - formic acid - water 60:3:8:6. Detection by dipping the hot plate (heated at 100°C for 2 min) into natural products reagent, followed by drying, dipping into polyethylene glycol 400 (10 g in 200 mL dichloromethane), and drying. Evaluation under UV 366 nm. With this method the geographical origin of the material can be determined. Toluene - acetone - formic acid 9:9:2 allows the discrimination of green from black and other speciality teas, based on the polyphenol pattern. Detection by dipping the hot plate (heated at 100°C for 2 min) into a solution of Fast Blue salt B, followed by detection under white light. For investigation of the alkaloid profil ethyl acetate - methanol - water 20:2.7:2, followed by detection under UV 254 nm is used. The amino acid profile is analyzed by using 1-butanol - acetone - acetic acid - water 7:7:2:4. Detection by dipping into ninhydrin reagent, followed by heating at 110°C for 3 min and evaluation under white light. The method for polyphenols was validated regarding specificity, stability, reproducibility, and robustness.
J. Liq. Chromatogr. Relat. Technol. 28, 2705-2717 (2005). TLC of selected bile acids (cholic, glycocholic, glycodeoxycholic, chenodoxycholic, deoxycholic, lithocholic, and glycolithocholic acid) on cyano phase with methanol - water, (acetonitrile - methanol 1:1) - water, acetone - water, dioxane - water in different volume compositions after saturation for 20 min. Detection by dipping into 20 % ethanolic phosphomolybdic acid solution, followed by heating at 120 °C for 20 min.
J. Liq. Chromatogr. Relat. Technol. 28, 2561-2569 (2005). TLC of cyanocobamides (benzimidazolyl, h-hydroxybenzimidazolyl, and 7-adeninyl cyanocobamides) on silica gel with 1-butanol - 2-propanol - water 10:7:10, and 2-propanol - 28 % ammonium hydroxide - water 7:1:2 in the dark. Detection under visible and UV light.
by high speed countercurrent chromatography. J. Liq. Chromatogr. & Relat. Technol. 30, 135-145 (2007). TLC of pinoresinol diglucoside and liriodendrin on silica gel (impregnated with 1 % carboxymethyl cellulose sodium) with the lower phase of chloroform - methanol - water 65:35:16. Detection by spraying with 10 % ethanolic sulfuric acid.
Whole Plant Powder by HPTLC. Chromatographia 65 (11-12), 767-769 (2006). Description of a simple, precise and accurate HPTLC method for the determination of rutin in the whole plant powder of Amaranthus spinosus Linn, which has been reported to have anti-diabetic, anti-thrombotic, anti-inflammatory and anti-carcinogenic activity. TLC of a methanol extract of the whole plant powder on silica gel with ethyl acetate - formic acid - methanol - water 100:9:11:17. Quantitative determination by densitometric measurement in absorbance mode at 363 nm. Linearity was between 10 and 60 µg/mL.
J. Liq. Chromatogr. Relat. Technol. 28, 1679-1691 (2005). HPTLC of the iridoid gycoside picroside I and picroside II on silica gel with chloroform - methanol 41:9 in a saturated twin-trough chamber. Quantitation by absorbance measurement at 290 nm.
J. Planar Chromatogr. 20, 267-274 (2007). Comparison of retention factors in pure water, log kw, determined by linear extrapolation and by a numerical method based on Oscik’s equation, and calculated values of log P as hydrophobicity indices for nine homologues s-triazines. The effect of mobile phase pH on solute retention was investigated as well as the effect of mobile and stationary phase properties on chromatographic behavior; 3 different organic modifiers (dioxane, acetonitrile, and tetrahydrofuran) and two stationary phases (RP-8 and RP-18) were used. Correlations of calculated log P values and log kw with carbon number confirm the usefulness of chromatographic techniques for studying the hydrophobicity of organic compounds. TLC on RP-18 with buffer - methanol mixtures in saturated sandwich chambers. Detection under UV light at 254 nm.
Chromatographia 67 (3-4), 268-274 (2008). HPTLC of 24beta-ethylcholesta-5,22E,25-triene-3beta-ol (ECTO) in the aerial part of Clerodendrum phlomidis (used as a chemical marker for the standardization of C. phlomidis plant extracts) on silica gel with chloroform - methanol 197:3. Detection by spraying with anisaldehyde reagent. Quantitative determination by densitometry in absorption mode at 650 nm. Linearity was between 150 and 400 ng/band with good correlation (r2 = 0.996).
