目的考察禾本科芦笋中总黄酮在D101大孔吸附树脂上静态与动态吸附性能,优选总黄酮纯化工艺。方法以静态吸附率、解吸率、静态吸附曲线为依据比较D101、AB-8和HPD100的静态吸附性能,优选最优树脂,然后对其动态吸附工艺进行考察。结果静态吸附量大小关系为AB-8> D101> HPD100,采用95%乙醇解吸附时解吸率大小顺序为HPD100>AB-8>D101。以D101大孔树脂进行动态吸附观察,动态优选的结果为5床容积（BV）的样品（水∶样品的容积比为1∶0.25）上样于径高比1∶5的D101大孔树脂柱,静置4 h,7 BV水洗,60 ml 90%乙醇洗脱,纯度提高了6.54倍。结论 D101大孔吸附树脂可以用于禾本科芦笋中总黄酮的纯化。

Objective To investigate the static and dynamic adsorption properties of total flavonoids in Asparagus of Gramineae on D101 macroporous resins and optimize the purification process for total flavonoids.Methods The static adsorption rate,desorption rate and static adsorption curve were determined to compare the static adsorption performance of D101,AB-8 and HPD100,and the best resin was selected optimally.Then the dynamic adsorption process was investigated.Results The relationship of static adsorption capacity was AB-8>D101>HPD100,and the order...
