J. Chromatogr. A 1533, 213-220 (2018). HPTLC coupled with effect-directed analysis for non-targeted screening of sunflower leaf extract for components exhibiting antioxidant, antibacterial and/or cholinesterase enzyme inhibitory effects. Characterization of the active compounds by HPTLC-electrospray ionization-high resolution mass spectrometry (ESI-HRMS) and HPTLC-Direct Analysis in Real Time (DART)-MS/MS. Identification of the two bioactive diterpenes, (-)-kaur-16-en-19-oic acid and 15-α-angeloyloxy-ent-kaur-16-en-19-oic acid, by NMR spectroscopy after targeted isolation via preparative normal phase flash chromatography and semi-preparative reversed phase HPLC.
thin-layer chromatography method for the simultaneous determination of apigenin and luteolin in Hygrophila spinosa T
Anders. J. Planar Chromatogr. 31, 437-443 (2018). HPTLC of apigenin (1) and luteolin (2) in Hygrophila spinosa on silica gel with toluene – ethyl acetate – formic acid 6:4:1. Quantitative determination by absorbance measurement at 349 nm. The hRF values for (1) and (2) were 64 and 54, respectively. Linearity ranged between 80-560 ng/zone for (1) and 40-280 ng/zone for (2). LOD and LOQ were 6 and 19 ng/zone for (1) and 2 and 7 ng/zone for (2), respectively. The intermediate precision was <3 % (n=3). Recovery was between 99.3 and 100.5 % for (1) and 99.5 and 100.8 % for (2).
J. Planar Chromatogr. 31, 367-376 (2018). HPTLC of folic acid (1) in the presence of its impurities pteroic acid (2) and para-amino benzoic acid (3) on silica gel with methanol – iso-propanol – water – glacial acetic acid 90:5:5:2. Quantitative determination by absorbance measurement at 280 nm. Linearity ranged between 0.4-4 μg/zone for (1), 0.1-1.5 μg/zone for (2) and 0.2-1.8 μg/zone for (3). LOD and LOQ were 132 and 398 ng/zone for (1), 33 and 99 ng/zone for (2) and 66 and 199 ng/zone for (3), respectively. The intermediate precision was <2 % (n=3). Average recovery was 100.0 % for (1), 98.6 % for (2) and 100.7 % for (3). Results obtained by the HPTLC method showed no significant difference when compared with those obtained by applying the reported RP-HPLC method.
for the quantifcation of dabigatran etexilate mesylate in the presence of its risky degradation products
J. Planar Chromatogr. 31, 461-468 (2018). HPTLC of dabigatran etexilate mesylate on silica gel with methanol ‒ ethyl acetate ‒ benzene 3:4:4. Quantitative determination by absorbance measurement at 225 nm. The hRF value for dabigatran etexilate mesylate was 82. Linearity was between 0.3 and 3 μg/zone. LOD and LOQ were 0.03 and 0.09 μg/zone. The intermediate precision was <2 % (n=3). Average recovery was 98.9 %.
