Fractional wavelet transform for the quantitative spectral resolution of the commercial veterinary preparations

Abstract

Fractional wavelet transform was applied to the quantitative spectral analysis of oxytetracycline and flunixin megluminein in a veterinary combination. A concentration set of 15 binary mixtures containing oxytetracycline and flunixin megluminein in the range of 4-36 mu g/mL oxytetracycline and 2-34 mu g/mL flunixin megluminein were processed by fractional wavelet transform (FWT) method. Partial least squares (PLS) and principal component regression (PCR) were applied to the FWT-coefficients to obtain FWT-PCR and FWT-PLS. The validity of the proposed FWT-PLS and FWT-PCR approaches were carried out by analyzing the synthetic binary mixtures of the related veterinary compounds. The proposed combined approaches were used for the quality control of the commercial veterinary formulation of compounds.
