摘　　要：以亚洲薄荷作为试验材料,采用超临界CO2萃取法,运用正交设计,针对萃取压力、萃取温度和萃取时间3个因素对薄荷挥发油萃取的影响进行了研究。结果表明,对薄荷挥发油萃取量的影响从大到小依次为萃取压力、萃取温度、萃取时间,超临界CO2萃取薄荷挥发油的最佳工艺参数组合为A3B2C2,即萃取压力12 MPa、萃取温度50℃、萃取时间1.5 h。The pressure,temperature and time of extracting volatile oil from Asian mint by supercritical CO2 method were studied through orthogonal experiment.The results showed that pressure has the greatest impact on extracting ratio;while time had minimal impact.The optimized extraction conditions were,pressure,12Mpa;temperature,55°C;time 1.5h.
