Determination of ropivacaine in human plasma by reversed-phase high performance liquid chromatography

  • Received Date: 2006-03-23
  • Objective: To establish an accurate and rapid method for determination of ropivacaine by RP-HPLC. Methods: The sample was treated by the addition of bupivacaine as an internal standard,extraction with aether and n-hexane,and dryed by N2.The residue dissolved in the mobile phase and injected into chromatographic system.The HPLC system consisted of AgilentC18 column(4.6 mm×150 mm,5μm)and mobile phase of 0.045 mol/L KH2PO4(pH3.0)-methol(55:45).Velocity of flow was 1.0 mL/min.The detection wavelength was 210 nm.Column temperature was 30℃. Results: The linear range was from 0.2509μg/mL to 5.018μg/mL with r of 0.999 6,the average recovery was 102.0%.RSD of Intra-day and Inter-day<15%.The results were accord with methodology. Conclusion: This method is quick and stable for ropivacaine monitoring in clinical research.
