ABSTRACT
<p><b>OBJECTIVE</b>To study the absorption and separation of different glycoside on different macropore resins.</p><p><b>METHOD</b>Take baikal skullcap root, cape jasmine fruit and white peony root as samples and study the different characterstics of absorption and separation of these samples on macropore resins such as D101 and so on.</p><p><b>RESULT</b>The static absorption effect of the the three aglycones on six different macropore resins is baicalin > lactiflorin > gardoside. Their elution are 75% CH3OH, 25% CH3OH, and 45% CH3OH. Their elution rates are 60%, 93%, and 93%.</p><p><b>CONCLUSION</b>Similar molecules may not have similar absorption abilities on same macropore resins, but the effect of absorption has something to do with the structures of the molecules, the more double-bonds the molecules have, the greater the absorption force the resins have.</p>
