摘　　要：本文合成了一系列用于从甜叶菊提取液中吸附分离甜菊甙的大孔吸附树脂，测定了它们的孔结构参数及吸附量，并比较了吸附量较高的五种树脂的循环使用性能及解吸性能。实验结果表明，Ｍ－３５树脂吸附量大，解吸率高，用树脂法工艺制备的甜菊甙产品纯度高，质量好。A series of macroreticular polymeric adsorbents for separating stevioside from stevialeaves were synthesized. The pore and adsorption properties were determined. The regenaration and adsorbing properties of five adsorbents were compared. The results show that the M-35 resin is most suitable adsorbent for the separation of stevioside.
