ABSTRACT
<p><b>OBJECTIVE</b>To evaluate colon targeting characteristic of Kuikang colon targeted pellets (KCP) with determination of residual baicalin and baicalein concentration in gastrointestinal tract (GIT).</p><p><b>METHOD</b>The baicalin and baicalein were assayed by HPLC. The recovery differences of the drug between KCP and conventional pellets from GIT were investigated, three and six hours after administration.</p><p><b>RESULT</b>The baicalin recovery of KCP (70%) from rat GIT was higher than that of CP (about 20%). Most of KCP were intact at 3 h after oral administration, and distributed in lower ileum. It indicated that release site of KCP was in lower ileum and colon. Six hours later, a small amount of baicalin was recovered in intestime, which showed that the release of baicalin from KCP was complete.</p><p><b>CONCLUSION</b>The determination of residual baicalin in rat GIT was feasibility for evaluating KCP. The result confirmed KCP of colon targeting property.</p>
