Determination of Aflatoxins B1 and B2 in Powdered Milk Using Modified Liquid Chromatography Method
Background & Aims: In this study, using a liquid-liquid microextraction method for pre-concentration trace amounts of aflatoxins, the amount of Aflatoxins B1 and B2 in powdered milk was determined. Determination of aflatoxins was done by using high-performance liquid chromatography coupled with fluorescent detector. Method: Samples were extracted by immunoaffinity column (IAC) clean-up, and the...
متن کاملUse of Temperature-controlled Ionic Liquid-assisted Dispersive Liquid-Liquid Microextraction Method for the Detection of Amoxicillin, Cloxacillin and Erythromycin Residues in Cow Milk using High Performance Liquid Chromatography
Background and Objectives: Different types of antibiotics are used indiscriminately in animal husbandry for the growth and treatment of livestock, which cause accumulation of antibiotic residues in livestock products such as milk. Long-term consumption of milk contaminated with antibiotic residues above the permissible limits is harmful to human health, causing antibiotic resistance problems. T...
متن کاملOxidation of Meloxicam by Streptomyces griseus
The aim of the present investigation was to biotransform the anti-inflammatory compound meloxicam by enzymes present in whole cells of five actinomycete cultures to produce novel bioactive derivatives. Among the actinomycetes screened, Streptomyces griseus NCIM 2622 was found to possess the enzyme system(s) that oxidize meloxicam into two metabolites whereas that present in S. griseus NCIM 2623...
متن کاملDetermination of some B Vitamins in Sour Cherry Juice Using Dispersive Liquid-liquid Microextraction Followed by High-performance Liquid Chromatography
Dispersive liquid-liquid microextraction method (DLLME) combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV) was used to determine thiamine (B1), nicotinamide (B3) and pyridoxine (B6) in sour cherry juice. This method was rapid, simple and sensitive. Separation was accomplished using a C18 column. The optimum chromatographic conditions were found to be: mobile ph...
متن کاملStudy of High Performance Liquid Chromatography Grade Water Quality in Iran
The use of high performance liquid chromatography (HPLC) grade water is very important for laboratory studies, especially food quality control. These studies have a great impact on diagnosing food health. Food health improves the health of the community and these two parameters are closely related. HPLC grade water is ultra-pure water with low UV absorption ability. This water is often purified...
