: fried products derived from potato, particularly potato crisp have been widely included in food basket of the households in the recent years in iran. potato crisp, among other products, is of great importance and is considered as competitive products. this product is in the list of the food products with high acrylamide content. therefore, due to the nutritional importance of this product and...

background and objectives: furfural (f) and hydroxymethyl furfural (hmf) are cyclic aldehydes, which are formed during the heat processing of foods. these chemical contaminants have received much attention due to their suspected health hazards and heat damage indicators. the aim of the present study was extraction and determination of f and hmf in baby-foods using dispersive liquid-liquid micro...

background and objectives: a method was developed and validated for determining 15 polycyclic aromatic hydrocarbons (pahs) in refined olive and refined pomace olive oils using high performance liquid chromatography coupled with a fluorescence detector. materials and methods: the sample preparation involved liquid–liquid extraction with organic solvent and low temperature clean-up. the low tempe...

An efficient and quantitative two phase freezing (TPF) method coupled with high performance liquid chromatography and UV-Vis detector was developed for the extraction, clean up and determination of clomiphene citrate (CLC) in plasma samples. The separation of two miscible solvents by TPF method permits that the CLC was efficiently removed from proteins and transferred into the relative aprotic ...

The traditional approach to assessing eicosanoids in cell cultures by liquid or gas chromatography coupled to mass spectrometry involves time-consuming procedures such as derivatisation, degradation, solid-phase extraction, liquidliquid extraction, thin layer chromatography and sometimes, combination of all these procedures prior to the injection of the sample in the chromatography system. The ...

an agar well diffusion bioassay method for determination of clarithromycin in human plasma, using micrococcus luteus atcc 9341 as the assay organism, was compared with a selective high-performance liquid chromatographic (hplc) method with uv detection. spiked plasma was used to prepare standard and control samples for both methods. the results of the bioassay analyses with spiked plasma samples...

efficient tuberculosis treatment requires the use of good quality medicines. the present study developed a method of dosage by high performance liquid chromatography (hplc) coupled with the dissolution of a combination of fixed doses of four anti-tuberculous (isoniazid, pyrazinamide, ethambutol hydrochlorate, rifampicine). the elaborated protocol was thereafter used to assess the quality of med...
