摘要
A highly sensitive and accurate novel response surface methodology (RSM)-assisted micellar enhanced synchronous spectrofluorimetric method was developed and validated for determination of vandetanib (VDB) in tablets, human plasma and urine. The method relied on enhancement of the fluorescence behavior of VDB in polyoxyethylene hydrogenated castor oil 40 (HCO 40) micellar medium and measuring the fluorescence using synchronous scan approach (Delta lambda=50 nm). Key factors affecting VDB fluorescence were optimized by RSM using Box-Behnken design. These factors were the type and volume of surfactant and pH of the buffer medium. Under the optimum conditions, the fluorescence-concentration plot was linear over the range 40-600 ng mL(-1); the limits of detection and quantification were 5.22 and 15.82 ng mL(-1), respectively. The suggested method was successfully applied to the analysis of laboratory-prepared tablets, spiked human plasma and urine samples. The results were statistically compared with those acquired by a pre-validated liquid chromatography-tandem mass spectrometric reference method and the results obtained from both methods were found to be in good agreement.
