Quantitative determination by absorbance measurement at 228 nm. The hRf value was 19. The validated calibration range was 400-2000 ng/band (r = 0.999). Recovery was 98.8-100.3 %. The intra-day precision as %RSD was 0.3-0.6 % and the inter-day precision 0.1-0.3 %. The LOD and LOQ were 97 ng and 294 ng, respectively.
J. AOAC Int. 93, 820-824 (2010). HPTLC of mexiletine hydrochloride on RP-18 with tetrahydrofuran - citrate buffer (pH 4.45) 3:7 and on amino phase with chloroform - tetrahydrofuran - hexane - ethylamine 30:20:50:1. Quantitative determination by absorbance measurement at 217 nm. Linearity was between 0.5 and 8.0 µg/spot. The accuracy was 99.6 % for the amino phase and 99.5 % for the RP-18 phase. The %RSD of intra-day and inter-day precision was 1.2 and 2.7 %, respectively; for both layers LOD and LOQ were 100 and 300 ng/zone, respectively.
J. Liq. Chromatogr. Relat. Technol. 34, 2606-2620 (2011). HPTLC of dexketoprofen trometamol in pharmaceutical formulations on silica gel with toluene - ethyl acetate 3:1 + 1 drop glacial acetic acid. Quantitative determination by absorbance measurement at 255 nm. The hRf of 1 was 45. Linearity was 20-120 ng/zone. LOD and LOQ were found to be 5 and 10 ng/zone. Repeatability and intermediate precision (%RSD, n = 6) were below 2 %. Recovery (by standard addition) ranged between 98.8 and 99.3 %. The HPTLC method was suitable to determine the purity of the drug available from various sources by detecting the related impurities.
J. Planar Chromatogr. 24, 72-76 (2011). HPTLC of sennoside A and B and gallic acid on silica gel with toluene - ethy acetate - formic acid - methanol 8:8:4:5. Quantitative analysis by densitometry at 270 nm. Linearity was between 114-427 ng/zone for sennosides A and B and 100-375 ng/zone for gallic acid. For sennosides A and B and gallic acid, hRf values were 26, 21 and 80, correlation coefficients were 0.95, 0.998, and 0.997, method precisions (%RSD, n = 6) were 1.1, 1.1 and 0.9 %, recoveries were 96.3-97.2 %, 98.1-100.8 % and 97.1-98.1 %, respectively. LOD andLOQ was 30 and 25 ng/zone for sennoside A, 20 and 99 ng/zone for sennoside B, and 66 and 82 ng/zone for gallic acid.
J. Planar Chromatogr. 24, 513-519 (2011). TLC of nabumetone (4-(6-methoxy-2-naphthyl)butan-2-one) on silica gel with n-hexane - chloroform - glacial acetic acid 4:1:1 with chamber saturation for 15 min. Quantitative determination by densitometry in absorbance mode at 270 and 330 nm. LOD and LOQ ranged from 0.23-1.00 µg/band. The recovery was between 98.9-101.7 % (at measurement wavelength 270 nm) and 99.6-101.7 % (at measurement wavelength 330 nm). The precision (%RSD) was below 2 % for all concentration levels. Linearity was between 0.3-3.5 µg/band. The hRf value was 72.
J. Liq. Chromatogr. Relat. Technol. 35, 1314-1324 (2012). HPTLC of 16 alkoxy-phenylbenzamide derivatives on silica gel pre-coated overnight with n-hexane - paraffin oil 19:1, with a mixture of organic solvent - water. The ratio of the organic solvent component (n-hexane, acetone, ethyl alcohol, methyl alcohol, and dioxane) changed in steps of 5 vol %. Quantitative determination by absorbance measurement under UV light (no wavelength given). Lipophilicity parameters (lipophilicity, extrapolated to zero concentration of organic modifier; specific hydrophobic surface area) were calculated from the retention data.
J. Planar Chromatogr. 25, 361-362 (2012). HPTLC of pigments in wheatgrass on sucrose-impregnated silica gel prepared by dipping the plates into a sucrose solution (400 g granulated sucrose/1 L distilled water), followed by heating at 110 °C for 20 min. Development with n-hexane - acetone 37:13. Detection by absorbance measurement between 400 and 800 nm. Sucrose impregnation prevents the degradation of the pigments during the analysis.
