59th Indian Pharmaceutical congress F-225, 443, (2007). HPTLC cinnamaldehyde in the bark powder of Cinnamomum zeylenicum on silica gel with toluene - ethyl acetate - formic acid 190:10:1. Densitometric evaluation at 295 nm for quantification. The method was linear within the range of 31 and 157 ng/zone. The identity of the compound was confirmed by over overlaying the UV spectra of sample and standard. Cinnamomum bark was found to contain 0.25 % of cinnamaldehyde. Limit of detection and quantification was 3000 and 9900 ng/mL, respectively.
Chromatographia 70 (1-2), 309-313 (2009). TLC on silica gel with acetonitrile - methanol - dichloromethane 2:1:2. The hRf value of dutasteride was 64. Separation of dutasteride from its degradation products (produced by acid and alkali hydrolysis, oxidation, photo degradation, dry and wet heat treatment) was good. Quantitative determination by absorbance measurement at 244 nm. Linearity was in the range of 100 - 600 ng/band and the correlation coefficient was 0.9943 (via peak area) The limit of detection and quantitation was 7 and 23 ng/band.
J. Chinese Trad. Patent Med. 30 (12), Supl. 4-6 (2008). TLC of the TCM drug extracts on silica gel with 1) dichloromethane - ethyl acetate - methanol - water 15:40:22:10; 2) petroleum ether (60-90 °C) - diethyl ether 3:2; 3) petroleum ether (60-90 °C) - ethyl acetate 25:2; 4) n-butanol - acetic acid - water 4:1:2; 5) chloroform - diethyl ether 1:1. Detection 1) by spraying with 10 % sulfuric acid in ethanol followed by heating at 105 °C until coloration; 2) under UV 365 nm; 3) under UV 254 nm.
Talanta, 80 (5), 2007-2015 (2010). Presentation of a method for determination of oxybutynin hydrochloride (OX) in presence of its degradation product and additives in its pharmaceutical formulations. UV spectrophotometry using the first derivative of ratio spectra and measurment at 216 nm. Chemometric analysis using principal component regression and partial least-squares. HPTLC of OX and its degradation products methylparaben and propylparaben on silica gel with chloroform - methanol - ammonia - triethylamine 500:15:2.5:1. Quantitative determination by densitometry at 220 nm. Comparison of the results obtained with all three methods showed no significant differences.
J. of Food Sci. & Biotechnol. 27(5), 129-133 (2008). TLC of gentamicin on silica gel with the lower phase of chloroform – methanol – 25 % ammonia 5:4:3 and after chamber saturation with the upper phase of the developing solvent. Detection by exposure to iodine vapor. Identification by comparison of the hRf values with the standards of the main components of gentamicin (Cl, C1 and C2). The results were compared with results obtained by HPLC and good agreement between both methods was found.
J. Planar Chromatogr. 28, 229-233 (2015). HPTLC of paroxetine in human serum on silica gel with toluene - acetone - ethanol - ammonia 25 % in water 9:5:2:1. Quantitative determination by absorbance measurement at 294 nm. Linearity was between 0.01 and 0.14 ng/µL. The intra-day precisions were between 0.9 % and 2.2 % (n=5) and the inter-day precisions were between 1.0 % and 3.9 % (n=9). The LOD and LOQ was 0.3 and 0.6 ng/zone, respectively. Recoveries were between 91.5 % and 96.5 %.
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.
(Detection of zimelidine (normud) and its main metabolites.) Fresenius Z. Anal. Chem. 319, 428-430 (1984).TLC of zimelidine and its main metabolite norzimelidine in biological materials on silica with 7 solvent systems, e. g. methanol -25 % NH3 99:1 or ethyl acetate - methanol -25 % NH3 85:10:5.
