J. Liq. Chromatogr. Relat. Technol. 40, 252-258 (2017). HPTLC of allocryptopine, berberine, boldine, chelidonine, papaverine, and emetine on cyano phase in different eluent systems. 2D-TLC of the same alkaloid standards on cyano phase in the first dimension with either A) methanol – diisopropyl ether – ammonia 15:83:2 or B) methanol containing 2 % acetic acid, and in the second dimension with either C) acetonitrile – water – formic acid – 1-butyl-3-methylimidazolium tetrafluoroborate 40:58.8:1:0.3 or D) acetonitrile – acetate buffer pH 3.5 – 1-butyl-3-methylimidazolium tetrafluoroborate 40:20:0.25. The best separation of the alkaloids was obtained with mobile phase C).
J. Chromatogr. Sci. 54 (4), 609-617 (2016). HPTLC of sulbutiamine (SUL) in the presence of different degradation products after subjecting the drug to stress conditions (according to ICH: neutral, alkaline and acidic hydrolysis, oxidation, photodegradation and dry heat degradation), on silica gel aluminum foil with acetone – methylene chloride – ammonia buffer (pH 8.5±0.2) 14:6:1. Densitometric evaluation at 254 nm. The calibration curve was between 0.4–5.0 µg/zone with good correlation coefficients. The LOD and LOQ were 110 and 330 ng/zone, respectively. Structure elucidation of the resulting degradation products by ESI-MS/MS. The results showed that the drug was completely degraded with 0.1 N NaOH, 1 N HCl and 30 % hydrogen peroxide, while it was partially degraded by 0.1 N HCl, 3 % hydrogen peroxide and UV light. The hRf of SUL was 46 and the zone was completely separated from all obtained degradation products.
(Xi Xian) by a validated high-performance thin-layer chromatographic method. J. Planar Chromatogr. 30, 516-520 (2017). HPTLC of chlorogenic acid (1) and caffeic acid (2) in the leaves of Siegesbeckia orientalis on silica gel with toluene ‒ ethyl acetate ‒ formic acid ‒ methanol 30:30:8:3. Quantitative determination by absorbance measurement at 366 nm. The hRF values for (1) and (2) were 19 and 83, respectively. Linearity was between 200 and 600 ng for (1) and (2). LOD and LOQ were 20 and 40 ng/zone for (1) and 59 and 120 ng/zone for (2), respectively. The intermediate/interday/intra-day precisions were below 3 % (n=3). Recovery was 99.0 %.
J. Chromatogr. Sci. 56 (1), 81-91 (2018). HPTLC of mixures of tamsulosin hydrochloride (TAM) with either tolterodine tartrate (TOL) or solifenacin succinate (SOL) in bulk drug and in combined dosage forms on on silica gel with ethyl acetate – methanol – ammonia 120:80:1. Quantification by densitometry at 224 nm. Linearity was between 0.1-0.7, 0.4-4 and 1-6 μg/band for TAM, TOL and SOL, respectively.
Food Chem. 255, 120-131 (2018). HPTLC of polyphenols (chlorogenic acid and rutin) in the peel, pulp, and the edible part of pepper on silica gel with ethyl acetate – dichloromethane – formic acid – acetic acid – water 100:25:10:10:11. Detection by spraying with Natural Product reagent and anisaldehyde sulfuric acid solution. Qualitative identification under UV 254 and 366 nm.
J. Chromatogr. A 1507, 124-131 (2017). Fast HPTLC-fluorescence detection (HPTLC-FLD) screening of the total ergot alkaloids in rye using lysergic acid amide (LSA) as chemical marker. Generally these substances are determined by HPLC-FLD or mass selective detection, analyzing the individual compounds. For analysis by HPTLC-FLD, transformation of the ergopeptine alkaloids selectively to LSA after an ammonium acetate buffered extraction step followed by liquid-liquid partition for clean-up. HPTLC on silica gel with isopropyl acetate – methanol – water – 25 % ammonium hydroxide solution 800:100:38:11. Quantitative determination using the enhanced native fluorescence of LSA and ergometrine at 313/>400 nm without any interfering matrix. The LOD and LOQ were 8 and 26 μg/kg LSA in rye, which enables the determination of the total ergot alkaloids far below the limit for rye. Recoveries were close to 100 % for different rye flours at relevant spiking levels. The screening method proved to be reliable, fast and efficient for the total ergot alkaloids in rye, and is a rapid alternative to the HPLC analysis of the individual compounds.
Food Chem. 278, 144-162 (2019). Review of methodologies, including TLC, HPTLC and its combination with mass spectrometry for the detection of potential biomarkers for the differentiation among species, varieties and cultivars of different foodstuffs, as well as metabolites as potential biomarkers for food authenticity according to production systems and for the detection of food spoilage and freshness.
using high-performance thin-layer chromatography. J. Planar Chromatogr. 31, 309-317 (2018). HPTLC of gardenin-E (1), gardenin-D (2), xanthomicrol (3), 5-desmethynobiletin (4), gardenin-A (5), and gardenin-B (6) in the sum resin of Gardenia lucida on silica gel with n-hexane – diethyl ether – 1,4-dioxane 4:6:1. Detection by dipping into natural product reagent (10 mL of 1 % methanolic diphenyl boryloxyethylamine), followed by dipping into PEG reagent (8.0 mL of 5 % ethanolic polyethylene glycol 4000). Quantitative determination by absorbance measurement at 335 nm. Linearity was between 0.33 and 1.67 μg/zone. LOD and LOQ were 90 and 300 ng for (1), 90 and 290 ng for (2), 90 and 320 ng for (3), 100 and 320 ng for (4), 60 and 210 ng for (5) and 80 and 280 ng for (6), respectively. The intermediate precision was <2 %. Recovery ranged from 96.0 to 99.3 %.
