چکیده انگلیسی
A simple, robust and reproducible HPLC method has been developed and validated for iron determination in biological matrices. It is based on chelation with desferrioxamine (DFO) and the measurement of the chelate ferrioxamine (FO). The method was developed to permit monitoring of iron bio-kinetics and estimation of iron status in experimental animals. The chromatography was performed on a stainless steel XTerra MS C18 column (Waters; 250 mm Ã 4.6 mm i.d., 5 μm) using a gradient of Tris-HCl buffer (10 mM, pH 5) and acetonitrile. The method was validated in terms of selectivity, linearity (0.3-80 nmol on-column), limit of detection (0.2 nmol on-column), low limit of quantification (0.3 nmol on-column), recovery (91-102%), intra- and inter-day reproducibility, stability, and robustness. The method's universal applicability was illustrated by monitoring plasma and heart iron kinetic profiles in rats after a single intraperitoneal (i.p.) injection of 200 mg/kg iron dextran.
