[Determination of spiramycin and tilmicosin in meat and fish by LC/MS].
A simple and reliable method using liquid chromatography-electrospray ionization-mass spectrometry (LC/ESI-MS) has been developed for the determination of the macrolide antibiotics spiramycin and tilmicosin in meat and fish. The drugs were extracted from meat and fish with 0.2% metaphosphoric acid-methanol (6:4), and the extracts were cleaned up on an Oasis HLB cartridge (60 mg). Positive ioniz...
متن کاملPreparation of a Major Metabolite of Iguratimod and Simultaneous Assay of Iguratimod and Its Metabolite by HPLC in Rat Plasma
Iguratimod is a new synthetic disease-modifying antirheumatic drug intended to treat patients with rheumatoid arthritis. A new method using recombinant human CYP450s yeast cells containing c-DNA expressed P450s was applied to identify the metabolic pathways of iguratimod and to prepare its metabolite. The metabolite was isolated, and its structure was identified by quadrupole time-of-flight-mas...

15 صفحه اولDetermination of Biologically Active Polyamines in Turkey Breast Meat by HPLC and Derivatization with Dansyl Chloride
BacBackground and Objectives: polyamines (putrecsine, spermidine and spermine) are widespread components, which can be found in most of the foods like meat, fruits, vegetables, cheese and wine. Studies show that reducing the level of polyamines in cells may help to slow down some cancer processes however, dietary polyamines may be required in wound healing, and for growth, maturation and regene...
