J. Planar Chromatogr. 22, 349-354 (2009). HPTLC of flurbiprofen (2-(3-fluoro-4-phenyl)phenylpropanoic acid) and degradation products on silica gel, prewashed with methanol, with chloroform - acetone - xylene 5:2:1 in a twin trough chamber saturated for 20 min. Quantitative determination by absorbance measurement (the authors report no wavelength). Linearity was between 50 and 600 ng/band. The limit of detection and quantification was 10 and 32 ng/band, respectively.
Ind. J. Pharma. Sci. 8(4), 211-212 (2009). TLC of clopidogrel bisulphate on silica gel with carbon tetrachloride - ethyl acetate - ammonia 50:3:2. Quantitative determination by absorbance measurement at 230 nm. Linearity was between 300 and 1500 ng. In comparison with the labeled claim the amount of clopidogrel in tablets was 99.2 %. The recovery was 99.2 % (via peak area).
Abstract No. F-239, 61st IPC (2009). HPTLC of hydrochlorothiazide, ramipril and telmisartan on silica gel with ethyl acetate - chloroform - methanol 6:3:1. Quantitative determination by absorbance measurement at 215 nm. The method was suitable for routine quality control of combined formulations.
Abstract No. F-236, 61st IPC (2009). HPTLC of pantoprazole and mosapride citrate on silica gel (pre-washed with methanol) with ethyl acetate - benzene - methanol - 25 % ammonia 48:35:15:2 at room temperature. Quantitative determination by absorbance measurement at 250 nm or 276 nm. The method was linear in the range of 3-7 µg/band for both drugs. Recovery was between 99.0 and 103.5 %.
J. Liq. Chromatogr. Relat. Technol. 33, 778-785 (2010). TLC of ofloxacin and pefloxacin on silica gel with acetonitrile - formic acid - water 40:3:7 in chamber saturated for 30 min. Quantitative determination by densitometry at 295 nm for ofloxacin and at 280 nm for pefloxacin. The regression equations were achieved using computer program STATISTICA 7.1.
Phytochem. Anal. 21, 219-223 (2010). HPTLC of safranal in saffron extract and in a safranal-loaded nanoparticle formulation on silica gel with n-hexane - ethyl acetate 9:1. Quantitative determination by absorbance measurement at 310 nm. The hRf of safranal was 51. Linearity was between 0.5 and 5.0 µg/zone. The intra-day and inter-day precisions were 1.08-2.17 and 1.86-3.47 %, respectively. LOD was 50 ng/zone while LOQ was 150 ng/zone. The average recovery was 99.9 %. The proposed method provides significant advantages in terms of greater specificity and rapid analysis.
Eur. J. Med. Chem. 45, 3719-3725 (2010). HPTLC of sulpiride and mebeverine on silica gel with ethanol - methylene chloride - triethyl amine 35:15:1. Quantitative determination by absorbance measurement at 221 nm. The hRF of sulpiride and mebeverine was 42 and 62, respectively. Linearity was between 0.4-1.4 µg/band for sulpiride and 0.2-1.6 µg/band for mebeverine. Detection and quantification limits were 0.02 and 0.3 µg/band for sulpiride and 0.04 and 0.2 µg/band for mebeverine. The intra-day and inter-day precisions had a %RSD lower than 2.6 %.Recoveries (by standard addition) were 99.3 % and 100.7 % for sulpiride and mebeverine, respectively. The proposed method showed comparable statistical results with the standard HPLC method
J. Planar Chromatogr. 24, 99-104 (2011). TLC of candesartan and losartan on silica gel with 1,4-dioxane - hexane - 99 % formic acid 50:50:1. Quantitative determination by densitometry at 258 nm for candesartan and at 243 nm for losartan, videoscanning at 254 nm for both drugs. The hRf value for candesartan was 47 and for losartan 35. Linearity was between 0.2 and 1.4 µg/band for both drugs with correlation coefficients of 0.9997 and 0.9981 for candesartan, and 0.9986 and 0.9982 for losartan, for densitometry and videoscanning, respectively. Robustness (%RSD, peak area) was less than 1.9 and 0.8 % for candesartan, and 2.2 and 0.9 % for losartan in densitometry and videoscanning, respectively. The repeatability and intermediate precision (%RSD, two lowest amounts) were less than 3.6 and 4.7 % for candesartan and less than 4.7 and 5.3 % for losartan. Mean recoveries for candesartan were 103.8-104.9 % for densitometry and 99.2-100.7 % for videoscanning; for losartan the respective values were 100.8-105.4 % and 98.6-99.2 %.
