Detection of Oxytetracycline Residue in Infant Formula by High-Performance Liquid Chromatography (HPLC)
Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...
متن کاملIdentification and Analysis of the Migration of Primary Aromatic Amines from Flexible Food Packaging by High-performance Liquid Chromatography (HPLC)
Background and Objectives: Primary Aromatic Amines (PAAs) are contaminants that can migrate from food flexible packaging. The main origin of these compounds is polyurethane adhesives used in the laminating process of multilayer films. Residual aromatic di-isocyanates of the reaction of adhesive polymerization migrate into the food, and are hydrolyzed to PAAs by the moisture of food. 2,4- and 2,...

متن کاملElution of residual monomers from dental composite materials.
AIM This study was designed to determine the type and amount of the monomers leached from the different particle sizes of the composite materials. MATERIALS AND METHODS Three different disk sizes (2, 4, 6 mm) prepared for each material group (Filtek Flow, Filtek A110, Filtek P60 and Filtek Supreme) were polymerised by LED and halogen light; the specimens were then placed in artificial saliva....
متن کاملHigh-performance liquid chromatography (HPLC) liquid chromatography-mass spectrometry (GC/ MS) analysis of some Sudanese propolis
Propolis is a natural resin of a variety of plant origins collected by honeybees to seal gaps and cracks in their hives. Propolis was used as a remedy of various diseases due to its versatile biological activities. At least 200 compounds have been identified in the world. The present study aimed to investigate the chemical composition of two samples of Sudanese propolis collected from El-Faki H...
