作者用四川西阳产邪蒿（Artemisia opiacea Hance）以溶剂汽油提取分离其青蒿素后残馀的母液进行水汽带馏,馏出物经无水硫酸钠脱水后得浅黄色透明精油,得率为5.13％,d（20℃）0.7674 n_D~(20)1.4289.精油用GC-MS进行分析鉴定,其中约含51种化
The authors used Artemisia opiacea Hance in Sichuan Province to extract the mother liquor from the residue of artemisinin by solvent gasoline extraction and steam distillation. The distillate was dehydrated with anhydrous sodium sulfate to obtain a pale yellow transparent essential oil. For 5.13%, d (20 °C) 0.7674 n_D ~ (20) 1.4289. Essential oils were analyzed and identified by GC-MS, which contains about 51 species of
