The supercritical fluid extraction( SFE)method was compared with HD. [Result] The productivity of HD was 0. 2 - 0. 4 g/100g Artemisa argyi leaves. And 4,11,11-trimethyl - 8-methylene-Bicyclo[7. 2. 0] undec- 4-ene( C15H24, 14. 76% ) was the major compound. The productivity of SFE was 0. 6 - 1 g/100g Artemisaargyi leaves. And caryophyllene oxide( C15H24O, 7. 25% ) was the major compound. The optimum extraction condition of HD is: slicing theleaves into pieces; adding 1L water/100g; soaking for 1h; extracting 5h. [Conclusion] SFE had a better productivity compared with HD in theuse of extracting volatile oil from Artemisia argyi leaves.Key wordsArtemisia argyi leaves; Volatile oil; Orthogonal design; Hydro distillation; Supercritical fluid extraction; GC-MS作者简介阳一兰( 1984 - ) ,女,湖南攸县人,助理工程师,从事化学分析与农产品质量安全研究,E-mail: lovingofsnow@ aliyun. com。
