An HPLC method was established for enantioseparation of ( R , S )‐atenolol (ATE) and determination of enantiomers in rat plasma. Marfey's reagent (1‐fluoro‐2,4‐dinitrophenyl‐5‐L‐alanine amide, FDNP‐L‐Ala‐NH 2 , MR) was used as chiral derivatizing reagent with detection of diastereomers at 340 nm. It was shown that the R ‐isomer eluted before the S ‐isomer. The method was validated for linearity, repeatability, limits of detection and limit of quantification (LOQ). Recovery of ATE at LOQ was 92.8% for ( R )‐ATE and 92.6% for ( S )‐ATE. Copyright © 2009 John Wiley & Sons, Ltd.
