摘　　要：考察了7种大孔吸附树脂对化香树果序多酚的吸附容量、解吸率、吸附等温线和吸附动力学、热力学,发现L-327F树脂对化香树果序多酚吸附量大、解吸容易、吸附速度快,是一种良好的吸附剂。因此,选择L-327F树脂纯化化香树果序多酚粗提液,并经3次平行实验得到产品纯度为56.58%,回收率为49.84%。Seven kinds of macroporous resins had been selected to purify the polyphenol from Infructescence of Platycarya Strobilacea Sieb.et Zucc.The comparative research on adsorption isotherm,adsorption capacity,desorption ratio and adsorption kinetics and thermodynamics had been done.The results showed that L-327F was an excellent adsorbent.L-327F was selected to extract and purify polyphenol from Infructescence of Platycarya Strobilacea Sieb.et Zucc.The recovery of polyphenol was 49.84%,and the content was 56.58% gotten by 3 times parallel experiments.
