A simple and rapid method has been developed for the quantification of Domperidone (DMP) and Paracetamol (PAR) through FT-IR in combined dosage form. The method involves the measurements of peaks of carbonyl group (C=O) at 1656 cm (PAR) and 1717 cm (DMP). An UV-Spectrophotometric method was also described for the simultaneous determination of DMP and PAR. The analytical results obtained with FT...

BACKGROUND Biotin, a water-soluble vitamin, is used as a co-factor by enzymes involved in carboxylation reactions. Biotinidase (BTD) catalyzes the recycling of biotin from endogenous and dietary sources. Biotinidase deficiency (BD) is an autosomal recessively inherited disorder of biotin recycling that is associated with neurologic and cutaneous consequences when untreated. The aim of the study...

The X-ray fluorescence spectrometry and the MA.BM.006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method,  and the formation of beads. Certified reference bauxite samples were used for the cali...

Carboxyhemoglobin (HbCO) saturation in a liquid specimen collected at medicolegal autopsy was analyzed firstly by a spectrophotometric method, which was first reported by Fretwurst et al, modified by Fukui and then modified by the authors, and secondly by a carbon monoxide-total hemoglobin (CO-Total Hb) method developed by the authors. In 70 blood specimens collected from the heart or blood ves...

To develop a new more accurate spectrophotometric method for detecting monoamine oxidase inhibitors from plant extracts, a series of amine substrates were selected and their ability to be oxidized by monoamine oxidase was evaluated by the HPLC method and a new substrate was used to develop a peroxidase-linked spectrophotometric assay. 4-(Trifluoromethyl) benzylamine (11) was proved to be an exc...
