Quantitative determination by absorbance measurement at 235 nm. The hRf values of (1) to (4) were found to be 58, 61, 68 and 79, respectively. Linearity was in the range of 200-1200 ng/band. Average recoveries were 98, 99.5, 98 and 99 % for compounds (1) to (4), respectively.
Quim. Nova. 35, 411-415 (2012). HPTLC of nifedipine in human serum on silica gel with chloroform - ethyl acetate - cyclohexane 19:2:2. Quantitative determination by absorbance measurement at 238 nm. The hRf of nifedipine was 31. Linearity was in the range of 0.02-0.25 ng/µL. Limits of detection and quantification were 0.7 and 0.9 ng/band, respectively. Intraday precision was in the range of 0.6-3.6 % (n=3) and inter-day precision was in the range of 1.2-3.6 % (n=9). Recovery was between 93 and 102 %.
J. Planar Chromatogr. 25, 72-76 (2012). HPTLC of mirtazapine on silica gel with methanol - chloroform 9:1. Quantitative determination by absorbance measurement at 294 nm. The hRf of mirtazapine was 56. Linearity was in the range of 400-2000 ng/band. The intermediate/interday/intra-day precision was below 2 %.
J. Planar Chromatogr. 25, 463-467 (2012). HPTLC of the enantiomers of the beta-blockers (bisoprolol, metoprolol, and propranolol) and a beta-2-agonist (salbutamol) on silica gel impregnated with Cu(II) complexes of L-threonine, L-serine, and L-tartaric acid, with different mobile phases. Limits of detection were within the range 0.19-0.26 µg for enantiomers of the selected compounds. L-Ser proved to be a very good ligand for exchange and successful enantio-resolution using common mobile phases.
CBS 107, 5-7 (2011). HPTLC of coenzyme Q10 in toluene extracts of soft gel capsules on silica gel (pre-washed by development from both sides with methanol) with toluene in the horizontal developing chamber from both sides. Detection under UV 254 nm. The hRf value of coenzyme Q10 is 20. Quantitative absorption measurement at 282 nm, evaluation via peak height. Linearity was in the range of 20-50 ng/band. Polynomial calibration ranged 20-150 ng/band. The parallel analysis of 60 samples (10 samples each from 6 batches) and 12 standards required only 86 min. The test for content uniformity was performed with 10 samples according to the European Pharmacopoeia and the USP 34 and the requirements were met.
J. Planar Chromatogr. 25, 162-167 (2012). HPTLC of famotidine (1), paracetamol (2), and ibuprofen (3) in combined dosage forms on silica gel with chloroform - methanol - ethyl acetate - acetic acid 215:161:591:32. Quantitative determination by absorbance measurement at 256 nm. The hRf values of compounds (1) to (3) were 21, 80 and 89, respectively. Linearity was in the range of 160-960 ng/zone for (1), 400-2400 ng/zone for (2) and 600-3600 ng/zone for (3).
