ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of Rhizoma Coptidis and Radix Rehmanniae with the different ratio on the pharmacokinetics of berberine in rats.</p><p><b>METHOD</b>24 rats were grouped to 4 groups randomly. Decoction, in which the proportion of Rhizoma Coptidis to Radix Rehmanniae is 10, 11, 14, 18 differently, was intragastrically given to the 4 groups. HPLC was used to determine concentration of berberine in serum. We adopted DAS 2.0 to analysis pharmacokinetic parameters of berberine.</p><p><b>RESULT</b>The concentration-time curves was all fitted to two-compartment model with a weight of 1/C2. Difference of 4groups in C(max), AUC(0-t), AUC(0-infinity), is significant (P <0.05).</p><p><b>CONCLUSION</b>Radix Rehmanniae of large dose can effectively enhance berberine's bioavailability in rats.</p>
