摘要
本论文研究了超临界CO2法萃取何首乌中磷脂的工艺条件。探讨了萃取温度、萃取压力、萃取时间、改性剂类型及改性剂含量对萃取率的影响。通过正交试验确定了萃取的最佳条件工艺条件为:萃取温度50℃,压力30MPa,Folch试剂(氯仿-甲醇为2:1)为改性剂且改性剂添加量为60%,萃取时间120min。
To study the technology of supercritical CO2 extraction of Phospholipid from Polygonum multiflorum Thtmb, the effects of pressure, temperature, time, kinds and content of entralner on the phospholipid extraction were explored. The optimum technological conditions were identified with the orthogonal design. The optimum technological conditions were as follows： temperature 50℃, pressure 30Mpa, Folch reagent as entrainer with content 60% and time 120min.
