Quantitative determination by absorbance measurement at 254 nm. The hRF values for (1) and (2) were 53 and 84. Linearity was in the range of 200-1600 ng/zone for both (1) and (2).
trimethoprim in medicated fish feed, fish tissues and in their veterinary pharmaceutical formulation by thin-layer chromatography–densitometry
J. Planar Chromatogr. 27, 113-119 (2014). HPTLC of sulphadiazine sodium (1) and trimethoprim (2) in medicated fish feed, fish tissues, and in their veterinary pharmaceutical formulation on silica gel with chloroform - toluene - ethanol - glacial acetic acid 9:9:2:2. Quantitative determination by absorbance measurement at 270 nm. The hRF values for (1) and (2) were 48 and 16, respectively. Linearity was in the range of 100-2000 ng/zone for (1) and 100-1000 ng/zone for (2). The intermediate/interday/intra-day precisions were below 3 % (n=3). Mean recoveries for (1) and (2) were 99.6 and 97.9 %, respectively.
J. Planar Chromatogr. 27, 328-332 (2014). HPTLC of crude extracts of micro-algae Dunaliella bioculata, Phaeodactylum tricornutum, and Scenedesmus obliquus on silica gel with dichloromethane - methanol 95:5. Data analysis of pictures digitally acquired at UV 254 nm and UV 366 nm included baseline correction, chromatogram alignment, principal component analysis (PCA) de-noising and diffusion drift correction. The workflow allowed to obtain a peak list containing hRF values, intensities and areas for statistical analysis.
CBS 115, 13-15 (2015). HPTLC of Java tea (Orthosiphon species) and standards rhamnazin, apigenin-4,5,7-trimethylether, 6-methoxyluteolin, luteolin tetramethylether, scutellarein tetramethylether, tangeretin,_x000D_ eupatorin, eupatorin-5-methylether, and sinensetin on silica gel with toluene – ethyl acetate – methanol 11:8:1 with chamber saturation for 20 min to the migration distance of 70 mm. Detection under UV 254 nm and 366 nm. Densitometric evaluation by absorbance measurement at 254 nm. Elution of zones with TLC-MS Interface into a single mass spectrometer. Together with the already established sinensetin, scutellarein tetramethylether, eupatorin, and eupatorin-5-methylether were determined as specific markers suitable for the identification of Orthosiphon aristatus (Blume) Miq. by HPTLC. The presence of these four markers in the flavonoid profile is specific for Java tea.
J. Chromatogr. A 1529, 93-106 (2017). Presentation of the quantitative effect-directed profiles of 77 industrially and freshly extracted botanicals like herbs, spices, vegetables and fruits, widely used as food ingredients, dietary supplements or traditional medicine for their quality assessment with regard to potential health-promoting activities. Fast assignment of single active compounds and evaluation of their contribution to the overall activity, originating from a food or botanical sample by combination of HPTLC hyphenated with UV/Vis/FLD detection and effect-directed analysis, using the 2,2-diphenyl-1-picrylhydrazyl radical, Gram-negative Aliivibrio fischeri, Gram-positive Bacillus subtilis, acetylcholinesterase and tyrosinase assays. Characterization of bioactive compounds of interest eluted using an elution head-based interface by HPTLC-UV/Vis/FLD-EDA-ESI-(HR)MS method. Demonstration of the excellent quantification power of the method by applying for rosmarinic acid, contents ranged from 4.5 mg/g (rooibos) to 32.6 mg/g (rosemary), for kaempferol-3-glucoside from 0.6 mg/g (caraway) to 4.4 mg/g (wine leaves), and for quercetin-3-glucoside from 1.1 mg/g (hawthorn leaves) to 17.7 mg/g (thyme). The mean repeatabilities (%RSD, n=18) were ≤ 2.2 % for the three compounds and the mean intermediate precision (%RSD, n=3) was 5.2 % over three different days.
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.
J. Chromatogr. Sci. 56, 317-326 (2018). Development of an accurate, sensitive and highly selective stability-indicating method for simultaneous determination of agomelatine (AGM) and its forced degradation products (Deg I and II) by HPTLC on silica gel with chloroform – methanol – ammonia 90:10:1. Quantitative determination by densitometry at 230 nm over the concentration range of 0.2-1.2 μg/band for AGM in pure form and human plasma, and 0.1-1 μg/band for both Deg I and II. The method was successfully applied for the analysis of AGM in pharmaceutical formulations. Statistical comparison of the results to those obtained by HPLC revealed its high accuracy and good precision.
