ABSTRACT
<p><b>OBJECTIVE</b>To build an experimental method to determine the content of puerarin in plasma, observe the effect of different combinations of traditional Chinese medicine preparation active parts on metabolism of puerarin in plasma of rats suffering cerebral ischemia attack after being orally administered the main active parts of Yangyin Tongnao granules.</p><p><b>METHOD</b>Absorption of puerarin in plasma was extracted by acetonitrile. Using hydroxybenzoate as interior standard, methanol-0.5% acetic acid water solution as mobile phase, ODS C(18) chromatography column (4.6 mm x 150 mm, 5 microm) as stationary phase, puerarin was detected at 248 nm.</p><p><b>RESULT</b>There is a good linear relationship for puerarin in the range 0.025-3.2 microg x mL-1, RSD < 10%, and the average recovery is 97.6%.</p><p><b>CONCLUSION</b>The method is sensitive, reliable, and can be well applied in this experiment. It can provide a method for determination of active components in TCM preparation in vitro. Different compatibility influences metabolism of components.</p>
