阿魏属和独活属植物的极轴平均长度分别为29.67μ m和34.07μ m,秩和检验表明二者差异显著;赤道轴平均长度17.07μ m和15.65μ m,差异不显著;极轴长/赤道宽的平均值分别为1.76和2.19,差异显著。

ConclusionThe extraction rate of volatile oils from Heracleum hemsleyanum Diels by supercritical CO2extraction process is higher than that of water vapor distillation,and the optimized extraction conditions are:extraction pressure 25MPa,extraction temperature 45℃ and flow rate of CO2 20L/h, and the yield of volatile oils is 0.65%.

超临界CO2萃取牛尾独活挥发油的萃取率较水蒸气蒸馏法高,最佳萃取条件为萃取压力25MPa,萃取温度45℃,CO2流量20L/h,挥发油收率为0.65%。

ConclusionMicrowave extraction has the highest yield in the shortest time. But volatile oil in Heracleum hemsleyanum Diels extracted by supercritical CO2 extraction or steam distillation has better quality. Thus the supercritical CO2 extraction is the best way.
