ABSTRACT
<p><b>AIM</b>To investigate the pharmacokinetics of osthole in rabbits and obtain the main pharmacokinetic parameters.</p><p><b>METHODS</b>A simple high-performance liquid chromatography (HPLC) method was developed to study the pharmacokinetics of osthole in rabbits by joining an internal standard (paeonal). Methanol-water (8020) was used as the mobile phase. According to the 3P87 pharmacokinetic program, the main parameters were calculated.</p><p><b>RESULTS</b>The osthole pharmacokinetics conforms to a two compartment open model after i.v. administration, T1/2 alpha = 5.81 min, T1/2 beta = 42.2 min, K21 = 0.036 0.min-1, K12 = 0.045 0.min-1, K10 = 0.054 0.min-1, AUC = 235 mg.min.L-1, CLs = 0.043 0 L.min-1.kg-1, Vc = 0.780 L.kg-1.</p><p><b>CONCLUSION</b>The pharmacokinetics of osthole after i.v. administration showed a rapid distribution and elimination process in rabbits.</p>
