Objective To establish a HPLC method for determination of the content and related compound A in Levocarnitine injection. Methods A column of silicagel column was adopted;and the mobile phase was the mixture of acetonitrile-phosphate buffer(0.05mol/Lsodium hydrogen phosphate,with phosphoric acid to adjust pH 5.5)=60∶40;The detection wavelength was set at 205nm;the flow rate was 1.0ml/min.Results Levocarnitine showed a good linear relationship in the range of 28.16~52.30μg (r=0.9999);The average recovery (n=6)was 99.70%(RSD=0.51%);The related compound A of Levocarnitine showed a good linear relationship in the range of 8.112~243.36 ng (r=1.0000);The average recovery (n=6) was 100.07%(RSD=0.36%). Conclusion The method is simple,accurate and reproducible,which can be uses for the quality control of Levocarnitine injection.
