英文摘要	The adsorption properties of 11 kinds of macroporous resins to hempseed hull antioxidant polyphenol were evaluated. It was found that HPD-600 had the higher adsorption ability than others. The results of static adsorption kinetics and thermodynamics of HPD-600 indicated that adsorption processing fitted the pseudo-first-order kinetics model and Langmuir and Freundlich models. The adsorption was an exothermic process so that high temperature was negative factor. The leaking ratio of total phenol during dynamic adsorption was significantly affected by concentration of sample solution other than flow rate. Gradient elution was employed in dynamic desorption process and eluate of 60% ethanol was target extract with the higher antioxidant activity and yield than others. The purified extract by HPD-600 resin had the stronger capacities in scavenging DPPH·, OH· and O2· radicals and the less content of impurity than crude sample. The HPLC measurement found that the content of N-trans-caffeoyltyramine and Cannabisin B increased significantly after purification. The results showed that HPD-600 macroporous resin was suitable for purification of hempseed hull antioxidant polyphenol.; EI; 0; 6; 77-87; 13
