ABSTRACT
<p><b>OBJECTIVE</b>To establish a method for detecting plasma polydatin using high-performance liquid chromatography (HPLC) and investigate the pharmacokinetics of polydatin in Beagle dogs.</p><p><b>METHODS</b>HPLC-based detection of polydatin was performed on a Hypersil-BDS C18 column with a mobile phase of methanol and water (3565) at the flow rate of 1.0 ml/min and the detection wavelength of 290 nm. The pharmacokinetic parameters of polydatin were calculated by non-compartment model statistics.</p><p><b>RESULTS</b>The standard curve was linear within the range of 0.21-21.0 microg/ml (correlation coefficient of 0.9995, n=5). The average recovery was 90% with a relative standard deviation no more than 8.0%. The limit of detection of the method was 0.1 microg/ml. The pharmacokinetic parameters of polydatin at 3 doses were obtained, with T((1/2)); of 89.95-/+19.96 min, 152.15-/+55.82 min, and 202.36-/+66.75 min, and AUC0-infinity of 300.14-/+51.33 g.min.ml(-1), 751.72-/+173.97 g.min.ml(-1) and 1521.12-/+310.02 microg.min.ml(-1), respectively.</p><p><b>CONCLUSION</b>The method we established allows effective detection of polydatin, whose pharmacokinetics conforms to the two-compartment model.</p>
