J. Liq. Chromatogr. Relat. Technol. 31, 763-771 (2008). TLC of 23 amino acids on silica gel with cetyltrimethylammonium bromide - n-butanol - n-octane - water microemulsion. Detection by spraying with ninhydrin reagent. Investigation of the effects of the hydrous content of microemulsion and structures of amino acids on the hRf values. Several amino acid mixtures were separated and determined using a microemulsion with 40 % hydrous content, which was compared with the traditional mobile phase ethanol - water - acetic acid.
Indian Drugs 45(12), 948-951 (2008). HPTLC of nebivolol hydrochloride and hydrochlorothiazide on silica gel with ethyl acetate - methanol - ammonia 17:2:1. Absorbance measurement at 280 nm. The method was linear in the range of 500-1500 µg/mL and 100-500 µg/mL for nebivolol hydrochloride and hydrochlorothiazide respectively. Recovery was 99.3-101.9 % for both compounds. The method is suitable for routine quality control.
Asian J. Chem. 19(7), 5634-5638 (2007). TLC of rabeprazole sodium and itopride hydrochloride on silica gel prewashed with methanol, with toluene - chloroform - methanol - 25 % ammonia 5:6:2. Quantitative determination by absorbance measurement at 225 nm. Linearity was between 120 and 280 µg/mL for rabeprazole sodium and 900 and 1900 µg/mL for itopride hydrochloride. The recovery (by standard addition method) was between 98.1 and 99.5 % for both drugs. The proposed method is precise and accurate and can be used for routine analysis of rabeprazole sodium and itopride hydrochloride in capsule formulation.
60th Indian Pharmaceutical Congress PA-195, (2008). HPTLC of trandolapril on silica gel with toluene - ethyl acetate - methanol - formic acid 5:16:2:1. The hRf value of trandolapril was 51. Trandolapril was subjected to different stress conditions like acidic and alkaline hydrolysis, oxidation, dry heat, wet heat, neutral condition and photodegradation. The degradation products were well resolved from the pure drug. Quantitative determination by absorbance measurement at 220 nm. Linearity was between 300-1800 ng/spot. The method was suitable for routine analysis of the drug in bulk and pharmaceutical dosage form.
Asian J. Chem. 18(4), 2669-2672 (2006). TLC of lamivudine and zidovudine on silica gel with toluene - methanol - n-hexane 14:3:2. Quantitative determination by absorbance measurement at 275 nm. Linearity for lamivudine and zidovudine was in the range of 0.8-2.0 and 1.5-4.0 µg/zone, respectively. The average recovery was 99.4 - 100.3 % for both drugs. The method can be applied for routine simultaneous estimation in combined dosage form.
J. Pharm. Biomed. Anal. 18, 271-274 (1998). HPTLC of cephalexin on silica gel (prewashed with the mobile phase) with ethyl acetate - acetic acid - water 7:2:1. Quantitative determination by absorbance measurement at 263 nm. The method was linear in the range of 200-1600 ng/spot, average recovery was 101 %. The analytical results obtained by HPTLC were comparable with the HPLC method of USP XXIII. The HPTLC method was suggested as alternative to the USP method considering the high throughput.
Correlation of lipophilicity with affinity for alpha-adrenoceptors. J. Planar Chromatogr. 22, 141-144 (2009). Determination of the relative lipophilicity of 14 1-substituted pyrrolidin-2-one by TLC on RP-18 with mixtures of acetonitrile and pH 7.0 Tris buffer with volume fractions of acetonitrile between 20 and 80 %, with chamber saturation for 2 h. Detection under UV light. Retention data obtained by this method were exponentially dependent on acetonitrile concentration and enabled estimation of the relative lipophilicity corresponding to pH 7.0 Tris buffer as mobile phase.
Anal. Chim. Acta 598 (2), 312-317 (2007). TLC of paroxetine hydrochloride on silica gel with butanol - acetic acid - water 16:4:1. The hRf value of paroxetine HCl was 48 and separation from the degradation products (produced by acid and alkali hydrolysis, oxidation and photodegradation) was good. Quantitative determination by absorbance measurement at 295 nm. The linearity was in the range of 300 - 1500 ng/spot and the correlation coefficient was 0.9903. The limit of detection and quantitation was 50 and 150 ng/zone, respectively.
