| 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. 475MPa,温度为55℃,CO2体积为30mL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>压力。 |

| Abstract: |
| 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, CO2 dynamistic extracting volume) were considered. SFE
optimize conditions: temperature 55℃, pressure 34. 475 MPa,CO2 dynamistic extracting
volume 30mL.The primary and secondary relation of the three variables is: temperature
>CO2 volume>pressure. |
