| 摘 要： | 研究了超临界CO2流体萃取柑橘皮精油的工艺条件并对其化学成分进行了分析。考察了在超临界CO2条件下,萃取时间、萃取压力、萃取温度、CO2流量和分离温度等因素对精油得率的影响,并通过正交试验优化得到最佳工艺条件,用GC-MS法测定柑橘皮精油的化学组成。结果显示最佳工艺条件为:萃取温度40℃,萃取压力20 MPa,分离温度50℃,萃取时间60 min,CO2流量25 kg/h。在此条件下,精油得率为0.86%。GC-MS测定结果显示柑橘皮精油主要由5,5’-二甲氧基-3,3’-二甲基-2,2’-联二萘-1,1’,4,4’-四酮组成(35.54%),其次还含β-羟基-甲基炔诺酮-甲基肟(24.60%)。

| Abstract: | Orange peel oil was extracted by supercritical fluid-CO2(SCF-CO2) and its constituents were analyzed by GC-MS.The effects of extraction time,pressure,temperature,CO2 flow rateand separate temperature on the oil yield were studied.The optimal conditions were determined by orthogonal experiments.The optimal conditions were as follows: extraction time 60 min,extraction pressure 20 MPa,extraction temperature 40 ℃,separation temperature 50 ℃.At the conditions,the oil yield was 0.86%.GC-MS analysis revealed that the main constituent of the oil was 5,5′-dimethoxy-3,3′-dimethy-2,2′-bina-phthalene-1,1′,4,4′-tetrone which amounted to 35.54%,and the other main constituent was β-hydroxy-methyl-norethisterone-methyl-oxime which amounted to 24.60 %. |
