Planta Med. 77, 548 (2011). HPTLC of glabridin (4-[(3R)-8,8-dimethyl-3,4-dihydro-2H-pyrano[6,5-f]chromen-3-yl]benzene-1,3-diol) on silica gel with toluene - dichloromethane - ethyl acetate 1:1:1. Detection under UV light at 286 nm.
J. Liq. Chromatogr. Relat. Technol. 32, 2437-2450 (2009). HPTLC calliterpenone (1) and calliterpenone monoacetate (2) in the leaves of Callicarpa macrophylla on silica gel with methanol - water 9:11. Quantitative determination by absorbance measurement at 210 nm. The hRf values of (1) and (2) were 43 and 73, respectively. Linearity was between 1-5 µg/zone for (1) and (2). LOD and LOQ were 230 and 780 ng/zone for (1) and 220 and 730 ng/zone for (2). Intra-day and inter-day precisions ranged between 1.3-1.7 % for (1) and 1.1-1.7 % for (2). Recoveries (by standard addition) were between 97.5-100.8 % for both.
J. Planar Chromatogr. 25, 548-553 (2012). New modified stationary phases obtained by chemical modification of diatomaceous earth from Filia and silica gel with trimethoxyethylphenylsilane. Separations on ethyl-phenylmodified adsorbents are similar to the separation on C8.
J. of Chromatogr. A 1248, 169-177 (2012). Purified oligomers of hyalobiuronic acid are indispensable tools to elucidate the physiological and pathophysiological role of hyaluronan degradation by various hyaluronidase isoenzymes. Establishment and validation of a novel sensitive, convenient, rapid, and cost-effective HPTLC method for the qualitative and quantitative analysis of small saturated hyaluronan oligosaccharides consisting of 2–4 hyalobiuronic acid moieties. HPTLC on amino phase with 1-butanol - formic acid - water 3:5:2 or 3:4:1. Detection 1) by spraying with orcinol in various concentrations of sulfuric acid; 2) by dipping into the reagent of orcinol in 10 % sulfuric acid and Morgan–Elson reagent; 3) by illuminating with white light and UV 366 nm after heating. The simple reagent-free in situ derivatization of 3) resulted in a detection limit of 7–19 pmol/band and LOQ of 37–71 pmol/band depending on the analyzed saturated oligosaccharide. Identification of the analytes by TLC-ESI-MS. The validated HPTLC method, as an alternative to sequential techniques such as HPLC and CE, can easily be automated and is applicable to the analysis of multiple samples in parallel.
J. Liq. Chromatogr. Relat. Technol. 35, 1213-1221 (2012). HPTLC of nicotine in cigarettes on silica gel with n-hexane - methylene chloride - methanol 4:16:3. Quantitative determination by absorbance measurement at 254 nm. Linearity was in the range of 0.1-1 mg/mL. Precision was estimated with an %RSD below 2.0. Limits of detection and quantification were 0.008 mg/mL and 0.02 mg/mL, respectively. The method provides acceptable intra-day and inter-day precision for nicotine. Recovery was between 97.5 and 98.4 %, respectively.

HPTLC fingerprint of four cycloartanes dikamaliartane-A (1) and dikamaliartane-B (2) and gummiferartane-1 (3) and gummiferartane-2 (4) in the gum resin from the leaf buds of Gardenia lucida or G. gummifera on silica gel with toluene – acetone 11:9. Detection by dipping in anisaldehyde reagent (anisaldehyde 0.5 % in methanol – acetic acid – sulfuric acid 17:2:1), followed by heating at 100 °C for 5 min. The hRf of compounds (1) to (4) were 60, 80, 90 and 70, respectively.
