Objective: To develop a method for determination of carnitine in serum using HPLC. Methods: The serum proteins were precipitated by acetonitrile and methanol. The organic extract was added derivatizing reagent and the solution was warmed to 60℃ for 2 hours. Atlantis C18 column (4.6 mm?150 mm,5?m)was used as stationary phase and methanol-ispropand-acetonitrile (35∶45∶20,v/v) as mobile phase; flow rate 1.0ml/min, UV wavelengh at 260nm. Results: The typical chromatogram from serum samples showed clear separation of carnitine. Y= 8490X-48200, r= 0.9999. Intra-day RSD was 1.6%-13.2%, and inter-day 1.8%-12.1%. The recovery rate was 98.5%. Conclusion: A method for determination of carnitine in serum using HPLC by adding derivatizing reagent was developed and it is simple, rapid and precise, and can be used for clinical test.
