J. Chromatogr. A 1127(1-2), 273-277 (2006). HPTLC of sucrose esters from the surface of leaves of Nicotiana tabacum L. on silica gel with n-hexane – ethyl acetate 1:3. Detection by spraying with aniline-diphenylamine reagent. Identification by off-line TLC-MS. Quantitative determination of sucrose esters–insecticides by indirect estimation through TLC of sucrose obtained after alkaline hydrolysis. Application of the method in the screening of sucrose esters in plant extracts in laboratory and field experiments.
J. Liq. Chromatogr. Relat. Technol. 28, 2597-2606 (2005). HPTLC of free sterol, and free fatty acids (cholesterol, triacylglycerol and methyl esters) on silica gel (prewashed with dichloromethane - methanol 1:1) with petroleum ether - diethyl ether - glacial acetic acid 80:20:1 in a twin-trough chamber saturated for 15 min. Determination of steryl esters with n-hexane - petroleum ether - diethyl ether - glacial acetic acid 50:25:5:1. Detection by spraying with 5 % ethanolic phosphomolybdic acid solution and heating for 10 min at 115 °C. Determination of polar lipids (cholesterol, phosphatidyl ethanolamine, phosphatidylcholine, lysophosphatidylcholine) with chloroform - methanol - water 65:25:4. Detection by spraying with a 10 % cupric sulfate solution and heating at 140 °C for 10 min. Quantitation by densitometry at 610 nm (for neutral lipids) and 370 nm (for polar lipids).
Ind. J. Pharm. Sci. 68 (6), 838-840 (2006). HPTLC of ofloxacin and ornidazole in tablet dosage form on silica gel with n-butanol - ethanol - ammonia 5:5:4. Quantitative determination by absorbance measurement at 295 nm. The method was found to be linear in the concentrate range of 1-5 ng/spot with recovery of 99.5-102.5 % for both compounds. The method was validated for linearity, accuracy, precision, repeatability, and specificity.
J. Liq. Chromatogr. Relat. Technol. 28, 677-691 (2005). HPTLC of podophyllotoxin and podophyllin on RP-18 in a twin trough chamber with acetonitrile - water 2:3. Densitometric measurement of lignans in absorption mode at 217 nm.
Thieme Medical Publishers Inc., New York (2006). This book presents the theoretical and technical information needed to perform reliable and reproducible high-performance thin-layer chromatography (HPTLC) to establish the identity, purity, quality, and stability of raw materials, extracts, and finished botanical products. The text provides a complete overview of the techniques and common applications of HPTLC in herbal analysis. Chapters covered are theoretical concepts (stationary phase, mobile phase, TLC results, densitometry), practical aspects of modern TLC (sample preparation, selecting the stationary phase, sample application, chromatogram development, derivatization, documentation, reporting and record keeping, TLC software, standardization), typical applications in herbal analysis, method development, and validation of qualitative and quantitative HPTLC methods.
Food Chem. 77, 263-265 (2002). HPTLC of trehalose on silica gel, impregnated with phosphotungstic acid of pH 2.5, with n-butanol – pyridine – water 8:4:3. Detection by spraying with a solution of 6.5 mM N-(1-naphthyl)-ethylenediamine dihydrochloride in methanol, containing 3 % sulfuric acid. The hRf values of raffinose, trehalose, maltose, sucrose, glucose, and fructose were 30, 41, 46, 53, 55, and 59, respectively.
J. Sep. Sci. 30, 3311-3315 (2007). HPTLC of lawsone in the leaves of Lawsonia alba on silica gel with chloroform – methanol 17:3. Quantitative determination by absorbance measurement at 334 nm. The hRf value of lawsone was 40 and selectivity regarding matrix was given. Linearity was between 100 and 1000 ng/zone. The precision was 1.72 % and recovery (by standard addition) was 98.8 %.
CBS 97, 9-11 (2006). HPTLC of trigonelline in fenugreek (Trigonella foenum-graecum) on silica gel in a saturated twin-trough chamber with n-propanol - methanol - water 4:1:4 over 80 mm. Quantitative determination by absorbance measurement at 269 nm. The hRf value of trigonelline was 46 and selectivity regarding matrix was given. Linearity was between 100 and 1200 ng/zone. The inter- and intraday precision was below 1 %. The limit of detection and quantification was 2.3 and 7.6 ng/zone, respectively. Recovery (by standard addition) was 99 - 101 %.
