摘要
在样品粒度为６０ 目时，采取静态、动态萃取相结合的操作方式，研究了萃取压力、温度及ＣＯ２ 体积对花椒挥发油萃取的影响。结果发现，萃取压力为３４．４７５ ＭＰａ，温度为５５℃，ＣＯ２ 体积为３０ ｍ Ｌ时，萃取花椒挥发油效果较好，３ 因素的主次关系为：温度＞ ＣＯ２体积＞
In this paper,a systematic method was used to optimize the supercritical fluid extraction (SFE) of Zanthorylum bungeanum maxim volatile oil.Overall 3 variables (pressure,temperature,CO 2 dynamistic extracting volume) were considered.SFE optimize conditions:temperature 55℃,pressure 34.475 MPa,CO 2 dynamistic extracting volume 30 mL.The primary and secondary relation of the three variables is:temperature>CO 2 volume>pressure.
