方法：采用大鼠在体肠循环模型和高效液相色谱法研究白术内酯Ⅰ在大鼠各肠段的吸收特性。
Method: The absorption kinetics was investigated using the method of in situ intestine absorption in rats and the samples were determined by HPLC.
结果表明循环逆流色谱法大大提高了难分离物质的分离度。
Compared with the chromatography, the resolution of the difficult separated compounds was enhanced by the recycling HSCCC.
