摘要:

应用超临界CO2 流体萃取技术,研究了乌桕籽皮油的萃取工艺。采用正交试验,考察了萃取压力、温度、CO2 流量三因素对乌桕籽皮油萃取率的影响效果。最佳萃取条件确定为:压力40MPa,温度36℃,CO2 流量20L/h,时间1h。利用GC 分析了乌桕籽皮油的成分组成,以期为乌桕籽的综合利用提供理论依据。

关键词: 超临界CO2流体, 乌桕籽皮油, GC分析

Abstract:

The extraction of Sapium sebiferum Roxb epidermis oil was carried out with supercritical fluid carbon dioxide technique, and the effects of extraction pressure, temperature and CO2 flow rate on extraction rate of Sapium sebiferum Roxb epidermis oil were investigated through orthogonal design.The results showed that the optimal extraction pressure, temperature, CO2 flow rate and time for the maximum extraction rate are 40 MPa, 36 ℃, 20 L/h and 1 h, respectively. Meanwhile the components of Sapium sebiferum Roxb epidermis oil were analyzed with gas chromatography (GC).

Key words: supercritical CO2 fluid, extraction, Sapium sebiferum Roxb epidermis oil, GC analysis
