59th Indian Pharmaceutical congress C-275, 291, (2007). HPTLC of asarone in a polyherbal formulation consisting of Acorus Calamus on silica gel with toluene - chloroform - ethyl acetate 18:1:1. Densitometry at 254 nm. The amount of asarone present in extract of sluizaro, a syrup formulation, was determined. The method was found to be suitable for routine quality control.
Chromatographia 69 (1-2), 151-155 (2009). HPTLC of paracetamol and caffeine on RP18W with methanol - acetic acid - water 250:43:707. Quantification by absorbance measurement at 254 nm. The limit of detection and limit of quantitation for paracetamol was 100 and 191 ng/spot and 40 and 76 ng/spot for caffeine. Recovery was in the range of 99.6 - 106.8 % and the repeatability of the method was RSD < 1.9 %.
J. Chinese Trad. & Herb. Med. 39 (12), 1818-1829 (2008). TLC of the extracts of the TCM drug on silica gel with 1) chloroform - methanol - acetone - ammonia 2:1:4:4; 2) chloroform - methanol - acetone - formic acid 32:8:4:7; 3) ethyl acetate - butanone - formic acid - water 10:1:1:1; 4) chloroform - methanol - water 13:7:2. Detection by evaluation under UV 365 nm and after spraying with 1) potassium iodobismuthate reagent; 2) a 1:1 mixture of 1 % potassium ferricyanide and 1 % FeCl3; 3) by spraying with 10 % sulfuric acid in ethanol followed by heating at 105 °C until coloration.
J. Pharm. Biomed. Analysis 54, 445-450 (2011). An improved HPTLC method has been developed for simultaneous estimation of lamivudine (LVD), stavudine (STV), and nevirapine (NVP) in fixed dose formulation. HPTLC on silica gel with ethyl acetate - methanol - toluene - 25 % ammonia 12:6:12:1. The hRf value is 24 for LVD, 38 for STV and 69 for NVP. Densitometric evaluation at 254 nm. The method was linear in the range of 42-209 ng/band (LVD), 38-192 ng/band (STV) and 42-208 ng/band (NVP). The recovery values were in the range of 98.4-102.2 % for all three compounds. The method was found suitable for quality control of LVD, STV and NVP in fixed dose formulation.
Acta Chromatographica 20(3), 423-437 (2008). HPTLC of rupatadine fumarate on silica gel with toluene – methanol – triethylamine 20:5:1. The hRf value was 61. Quantitative determination by absorbance measurement at 264 nm. The linearity was in the range of 400–1400 ng/band (r=0.9992). The limits of detection and quantitation were 67 and 202 ng/band, respectively. Moreover, rupatadine fumarate was subjected to acid and alkaline hydrolysis, oxidation, and photochemical and thermal degradation and underwent degradation under all these conditions. The method proved to be repeatable, selective, and accurate for the analysis of the drug by statistical analysis, and is able to separate the degradation products from the drug.
J. Chil. Chem. Soc. 59, 2405-2408 (2014). HPTLC of trazodone in human serum on silica gel with toluene - acetone - ethanol - ammonium 18:14:4:1. Quantitative determination by absorbance measurement at 290 nm. The hRF values of trazodone and its metabolite were 82 and 39, respectively. Linearity was between 0.2 and 2 ng/zone. The intermediate intra-day and inter-day precisions were below 3.5 % (n=3). The LOD and LOQ were 16 and 48 pg/zone, respectively. Recoveries for trazodone were in the range of 94.7-99.0 %.
J. Chromatogr. Sci. 56 (1), 92-98 (2018). TLC for direct enantiomeric resolution of the racemic β-adrenolytics bisoprolol (1), atenolol (2), propranolol (3), salbutamol (4) and carvedilol (5) by TLC using bovine serum albumin (BSA) as chiral additive in the stationary phase and with different compositions of simple organic solvents without buffer or inorganic ions. Systematic investigation of the effect of variation in pH, temperature, amount of BSA as the additive, and composition of mobile phase on resolution. Detection by exposure to iodine vapors. The five entantiomers were separated in the elution order (1), (2), (3), (4), and (5). The LOD was 0.7, 1.2, 0.8, 1.6 and 0.9 μg/zone for (1), (2), (3), (4), and (5), respectively.
