A simple high-performance liquid chromatographic (HPLC) method has been developed for the determination of epimedin C in rat plasma and applied to a pharmacokinetic study in rats after administration of Herba Epimedii extract. After addition of carbamazepine as an internal standard plasma samples were extracted with ethyl acetate. HPLC analysis of the extracts was performed on a Hypersil ODS2 analytical column using acetonitrile -0.4% acetic acid (25:75, v/v) as the mobile phase. The UV detector was set at 260 nm. The standard curve was linear over the range 0.05-4.0 microg/mL. The lower limit of quantification was 0.05 microg/mL. The HPLC method developed could be easily applied to the determination and pharmacokinetic study of epimedin C in rat plasma after giving the animals Herba Epimedii extract.
