RP-HPLC Analysis and Pharmacokinetics Study of Serum Carthamin in Mice / 中国药房

ABSTRACT

OBJECTIVE:To establish an RP-HPLC analysis of Carthamin in mice and to study its pharmacokinetics.METHODS:The serum concentration of Carthamin was determined by RP-HPLC.The blood concentration-time curve was established and the main pharmacokinetic parameters were computed.RESULTS:The linear range of Carthamin was 0.558～55.8 ?g?L-1(r=0.999 2),with the lowest limit of detection at 0.005 ?g?L-1Carthamin in vivo assumed two-compartment model and rapid absorption.CONCLUSION:The proposed method is simple,sensitive and reproducible,and it met the standard for pharmacokinetic study.
