摘要: 本文介绍了超临界CO2萃取罗勒干叶中挥发油的提取分离工艺,重点研究了前处理浸提时间,超临界CO2萃取压力、温度、时间对出油率的影响。应用正交实验优化出:影响超临界CO2萃取的主次因素为C>A>B(A为萃取压力,B为萃取温度,C为萃取时间);较佳工艺参数:浸泡时间150min,SC-CO2萃取压力为18MPa,温度为55℃,时间为120min,流量为25L/min,得到超临界CO2萃取罗勒挥发油的出油率高达2.8‰。

Abstract: The article introduced technology of supercritical CO2 on extracting volatile oil from dry leaves of Ocimum basiliamLinn var. pilosum (wild. )Benth, putting emphasis on effects of marinating time, SC-CO2 extracting pressure, temperature and timeon the extraction efficiencies.The optimum technology parameters were investigated by the orthogonal design. The factorsinfluencing this extraction efficiency were as follows: C>A>B (A: extraction pressure,B: extraction temperature, C: extrac-tion time), the optimum extraction conditions were: marinating time 150min,extraction pressure 18MPa,extraction temperature55℃, extraction time 120min and flux 25L/min. The maximum of extraction efficiencies was up to 2.8‰.

Key words: Ocimum Basilicum L., supercritical CO2, extraction, volatile oil
