摘　　要：通过运用超临界二氧化碳萃取技术萃取藿香梗浸膏,考察萃取时间、CO_2流量、萃取温度以及萃取压力这4个因素对藿香梗浸膏萃取率的影响。对这4个因素分别进行多次单因素实验,用单因素实验数据结果进行相关正交实验并得到相应的实验数据。利用二次响应曲面法将上述数据拟合,得到超临界二氧化碳萃取藿香梗浸膏的最佳工艺条件和数学模型。The effects of extracting pressure, extracting temperature, extracting time and CO2 flow rate in the extraction of the patchouli-stem concrete by supercritical carbon dioxide fluid have been investigated. Single factor experiments and orthogonal experiments have been designed for four factors respectively. The experimental data have been fitted by quadratic response surface methodology and then the optimal technological conditions of extraction can be obtained. Finally, the approximate mathematical model of extraction will be concluded.
