Objective:To set up an HPLC method for the determination of propafenone enantiomers in the human plasma and to provide analytic techniques for the clinical pharmacological study of the propafenone enantiomers. Methods:The internal standard method and reversed phase high performance liquid chromatography were used for the determination of the concentrations of standard substances of S propafenone and R propafenone and those of the coresponding enantiomers extracted from the human plasma. The mobile phase was methanol water glacial acetic acid triethylamine in a ratio of 53∶47∶1.6∶0.5 by volume and the stationary phase was a column composed of Shaudou Hypersil ODS. Li 1115 served as the internal standard and the flow rate was 1.2 mL·min 1 . The detection was carried out at UV 254 nm. Results:The sensitivity of the method was 0.01 AUF, the lowest detection limit was 20 ng, the linear range of the standard curve was from 50 μg·L 1 to 800 μg·L 1 . The average rates of recovery of S propafenone and R propafenone were 86.03% and 84.17%, respectively, their RSD within a day being 8.2% and 6.6%, respectively. Conclusion:The method was shown to have a high sensitivity and good reproducibility. It may therefore be used in the clinical pharmacological study of propafenone enantiomers.
