Simultaneous Spectrophotometric Determination Of Difloxacin And Enrofloxacin In Urine Samples By Partial Least Squares Regression (Pls) And Direct Orthogonal Signal Correction-Partial Least Squares Regression (Disc-Ols) Methods, Kuldeep Kaur, Ashok Kumar Malik, Baldev Singh, M. Godarzi

The Thai Journal of Pharmaceutical Sciences

Simultaneous determination of difloxacin and enrofloxacin using two chemometric methods, partial least squares regression (PLS) and direct orthogonal signal correction-partial least squares regression (DOSC-PLS) is described in this paper. The simultaneous determination of these drugs is difficult due to spectral interferences. The calibration graphs were linear in the range of 1-10 μg mL-1 and 1-9 μg mL-1 with detection limits of 0.52 and 0.15 μg mL-1 for difloxacin and enrofloxacin, respectively. The experimental calibration matrix was designed with 25 mixtures of these drugs. The PLS and DOSC-PLS were used for multivariate calibration of spectrophotometric data. The root mean square error …

Facile Derivative Uv Spectroscopy Method: Simultaneous Estimation Of Tinidazole And Fluconazole In Combined Tablet Dosage Form, Saurabh Pandey, Preeti Pandey, Shaifali Dubey, Udisha Chaturvedi, Awani K. Rai

The Thai Journal of Pharmaceutical Sciences

Two derivative spectrophotometric methods have been developed for simultaneous determination of tinidazole and fluconazole in pharmaceutical formulations. The first method depends on utilization of first derivative UV spectrophotometry, with zero-crossing and peak-to-base measurement at 260.57 & 264.23 nm for fluconazole and 263.86 & 318.85 nm for tinidazole. The second method, compensation technique depends on first derivative of the ratio-spectra by measurements of the amplitudes for tinidazole and fluconazole. Calibration graphs were established for tinidazole and fluconazole in the range of 10-100 μg ml-1 and 2-20 μg ml-1, respectively. All proposed methods have been extensively validated. The results were found to …

Detection and quantification were performed by UV/Vis detection at 225 nm. The lower limit of detection and quantification were 0.01 μg†mL-1 and 0.25 μg†mL-1 for cefixime, 0.03 μg†mL-1 and 0.39 μg†mL-1 for cloxacillin. The calibration curves were linear over the concentration range 0.5 to …
