چکیده انگلیسی
A stereospecific method of analysis of racemic isosakuranetin (5,7-dihydroxy-4â²-methoxyflavanone) in biological fluids is necessary to study pharmacokinetics. A simple high-performance liquid chromatographic method was developed for the determination of isosakuranetin enantiomers. Separation was achieved on a Chiralpak® ADâ¢-RH column with ultraviolet (UV)-detection at 286 nm. The standard curves in urine were linear ranging from 0.5 to 100.0 μg/ml for each enantiomer. The mean extraction efficiency was >88.0%. Precision of the assay was <15% (CV) and was within 12% at the limit of quantitation (0.5 μg/ml). Bias of the assay was <15% and was within 6% at the limit of quantitation. The assay was applied successfully to stereospecific disposition of isosakuranetin enantiomers in rat urine.
