设计并合成了一系列疏水性 (包括非极性和不同极性 )和亲水性大孔吸附树脂 ,研究它们对甜叶菊糖甙的吸附性能与吸附机理 .紫外光谱与HPLC研究表明 ,吸附剂的骨架结构和极性对总甙吸附量及其对甜菊甙和莱鲍迪甙A的吸附选择性有显著影响 .并利用树脂对不同极性糖甙吸附的弱选择性作用成功地分离出莱鲍迪甙A产品 .
A series of hydrophobic (including non-polar and different polar) and hydrophilic macroporous adsorbents were designed and synthesized to study their adsorption and adsorption mechanisms on stevia.Ultraviolet spectroscopy and HPLC showed that the adsorbent Of the skeleton structure and polarity of the total glycoside adsorption capacity and its stevioside and rebaudioside A adsorption selectivity has a significant effect and the use of resin for different polar glycoside adsorption of a weak selective role in the successful separation of Levin Bowdy glycosides A product.
