摘　　要：Ultrafiltration （UF） experiments were subjected to the concentration of Shi- itake polyphenol（SP） with ultrasound （US） enhancement, by which the effects of the main parameters such as ultrasonic power, transmembrane pressure, temperature and axial flow-rate on the membrane fluxes were analyzed, and then the SP of the ultrafiltrate after follow-up resin adsorption by HPLC was investigated. The results in- dicated that US could significantly enhance the membrane fluxes. The optimal con- ditions obtained was as follows： 0.60 W/cm2 US power, axial flow-rate of 80 L/h, operation temperature 30 ~C, transmembrane pressure 0.10 MPa. US increased the absorption capacity of the absorbent resin during the following stage. The HPLC analysis also showed that catechins were purified to some extent as the ultrafiltrate was treated by US and macroporous resin, indicating the technology of US en- hancement coupled with UF showed the potential for concentration and purification of SP by absorbent resins.Ultrafiltration(UF) experiments were subjected to the concentration of Shiitake polyphenol(SP) with ultrasound(US) enhancement, by which the effects of the main parameters such as ultrasonic power, transmembrane pressure, temperature and axial flow-rate on the membrane fluxes were analyzed, and then the SP of the ultrafiltrate after follow-up resin adsorption by HPLC was investigated.
