A new, simple and sensitive spectrofluorimetric method has been developed for the determination of aliskiren (ALS) in dosage forms and human urine. The method is based on the reaction between ALS and fluorescamine in borate buffer solution, pH 9, to give a highly fluorescent derivative which is measured at 482 nm after excitation at 382 nm. The factors affecting the reaction were carefully studied. The fluorescence intensity concentration plots were rectilinear over the range 140–1400 ng/mL with a limit of detection 13.47 ng/mL and limit of quantitation 40.81 ng/mL. The developed method was successfully applied to the analysis of the drug in tablets and human urine; the average recoveries (n = 6) were 99.88 ± 0.38% and 99.57 ± 0.44%, respectively. The analytical performance of the method was fully validated and the results were satisfactory. The stability of the drug was studied by subjecting it to acidic, basic, oxidative and thermal degradation. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

A simple and rapid liquid chromatographic method was developed and validated for the determination of triclabendazole with high accuracy and precision within 6 min. Good chromatographic separation was achieved using a CLC Shim‐pack C8 (250 × 4.6 mm, 5 µm particle size) using the mobile phase containing a mixture of 0.02 m phosphate buffer and methanol with a ratio of (20 : 80 v/v) at pH 4.0 was pumped at a flow rate of 1.2 mL/min with fluorescence detection for the first time at 338 nm after excitation at 298 nm. Losartan potassium was used as an internal standard. The method showed good linearity in the ranges of 0.05–2.0 µg/mL with limits of detection and quantification of 14.1 and 42.6 ng/mL, respectively. The suggested method was successfully applied for the analysis of triclabendazole in tablets. The high sensitivity of the method enabled the determination of the studied drug in spiked human plasma with mean percentage of recoveries of 99.79 ± 5.09. Statistical evaluation of the data was performed according to ICH Guidelines. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

A highly sensitive, simple and rapid spectrofluorimetric method was developed for the determination of amisulpride (AMS) and bumidazone (BUM) in tablet form. The proposed method is based on measuring the native fluorescence of the studied drugs in methanol at 360 and 344 nm after excitation at 276 and 232 nm for AMS and BUM, respectively. The fluorescence–concentration plots were rectilinear over the ranges of 5.0–60.0 ng/mL for AMS and 0.5–5.0 µg/mL for BUM. The lower detection limits were 0.70 ng/mL and 0.06 µg/mL, and the lower quantification limits were 2.0 ng/mL and 0.18 µg/mL for AMS and BUM, respectively. The method was successfully applied for the analysis of AMS and BUM in commercial tablets. Statistical evaluation and comparison of the data obtained using the proposed and comparison methods revealed good accuracy and precision for the proposed method.
