摘要
影响超临界流体萃取天然产物有效成分传质的因素很多,本文分析了颗粒度、含水量等预处理技术对萃取效果的影响,其中重点介绍了各种原料破壁技术的应用状况,并全面阐述了萃取过程中压力、温度、CO2流量、时间、填充量等因素的影响和夹带剂、外场辅助等强化技术的研究进展。
The effect of mass transfer between supercritical CO2 fluid and active principle of natural product could be influenced by so much factors. In this paper, the effect of pretreatment technique include granule diameter, water capacity, crash of cell wall was analysed. At the same time, the factors of extraction pressure, extraction temperature, flow of CO2, extraction time, filler level etc was expatiated, the develop of modifier and outfield assistant for intensify extraction was introduced.
