An efficient molecularly imprinted solid phase extraction (MISPE)-spectrofluorimetric method was developed to sensitively determine danofloxacin (DAN) in milk samples. Solid phase extraction procedure using MISPE cartridges was first performed on milk samples and then spectrofluorimetric determination was done at 546 nm using an excitation wavelength of 285(More)
Food preference behaviour of Funambulus pennanti Wroughton was studied offering four different types of cereals, viz. wheat, millet, maize and rice in three textural forms, viz. whole dry, cracked and whole moist in no-choice, bi-choice and multiple-choice to the experimental squirrels. The mean daily intake of F. pennanti in no-choice has been recorded to(More)
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(More)
The present study reports the synthesis of silver nanoparticle using Morus nigra leaf extract were used as reducing agent for reduction of silver nitrate solution. The synthesis of silver nanoparticles was analyzed by UV-Visible spectroscopy, Scanning Electron Microscopy. The SEM analysis has shown that size of silver nanoparticles synthesized from leaves(More)
A simple, rapid and sensitive constant wavelength synchronous fluorescence method is developed for the determination of danofloxacin (DAN) in pharmaceutical formulations and its residue in milk based on Al(III) enhanced fluorescence. The synchronous fluorescence intensity of the system is measured at 435 nm using ∆ λ = 80 nm and an excitation wavelength of(More)
Three chemometric methods; partial least squares regression (PLS), principal component regression (PCR) and least-squares support vector machines (LS-SVM) were applied for simultaneous determination of carbidopa and levodopa in synthetic mixtures and real samples. The simultaneous determination of these drugs is a difficult problem due to spectral(More)
Amitriptyline.HCl (AMI) and clomipramine.HCl (CMI) react with eosin Y (EY) in pH 3.8 NaAc-AcH buffer solution to form ion association complex which results in quenching of fluorescence of EY and appearance of a new resonance Rayleigh scattering (RSS) spectrum at 620 nm. The spectral characteristics of absorption, fluorescence and RSS spectra have been(More)
