Abstract:
AIM:To establish a HPLC method for determinaton of sodium ferulate (SF) in Beagle dog plasma and to study the pharmacokinetics of SF tablets. METHODS: Sodium ferulate in plasma was extracted with ether,separated on a Kromasil C_ 18 column (150 mm?4.6 mm,5 ?m) and the peak height ratio of sodium ferulate to the internal standard tinidazole was measured.Plasma concentration of SF was determined using acetonitrile-water-acetic acid(20∶79.2∶0.8) as the mobile phase and the flow rate was 0.8 ml/min.SF was detected at 320 nm. RESULTS: SF and the internal standard were separated completely under the condition described above.SF was linear in the range of 0.02～50 ?g/ml(r=0.9995).The accuracy,precision and sensitivity were eligible for analyse of bio-pharmic samples. CONCLUSION:A sensitive and accurate HPLC method for the quantitative determination of SF in the plasma of Beagle dog is developed and it is applicable to the determination in plasma and pharmacokinetic study of SF.
