目的：确定中药抗溃疡性结肠炎生物黏附剂中所选用促渗剂的种类及其用量。方法：采用大鼠在体灌流模型处理灌肠液,并采用HPLC法测定秦皮甲素在灌肠液中的含量。结果：0.5%,1%,2%,3%,4%,5%的薄荷脑作为促渗剂时,秦皮甲素的吸收度分别为0.015742,0.022566,0.016520,0.014586,0.012946,0.012818μg.mL-1.cm-1;0.5%,1%,2%,3%,4%,5%的冰片作为促渗剂时,秦皮甲素的吸收度为0.015664,0.016067,0.013753,0.012597,0.011899,0.011449μg.mL-1.cm-1。结论：薄荷脑和冰片对灌肠Ⅰ号中秦皮甲素都有较强的促渗透作用,1%薄荷脑及1%冰片对秦皮甲素的促透作用最明显。两药比较,薄荷脑的促透效果更强。
