Objective: To study the organ targeting for freeze-dried injection of Oxymatrine- Polybutylcyanoacrylate-Nanoparticles (OMAT-PBCA-NP) in rats. Method: The content of oxymatrine in major organs of rats after injected with OMAT-PBCA-NP was investigated by high performance liquid chromatography. HPLC was carried out on a Kromasil C18 column (4.60 mm×250 mm
5 μm)with the mobile phase consisting of methanol and water and triethylamine(50∶50∶0.02)
the column temperature was 20 ℃ and UV detection wavelength was 210 nm
the flow was 1 mL·min-1 and the injection volume was 10 μL. Result: The calibration curve of oxymatrine was linear in the concentration range of 50-400 mg·L-1(r=0.999 0)

the content of oxymatrine was highest in the liver with significant difference from other organs (P<0.01). Conclusion: OMAT-PBCA-NP has good targeting for liver.
