수증기 증류법을 이용하여 약용 쑥으로부터 정유를 추출 하였다. 정유는 GC-MS를 이용하여 분석하였다. 가열처리 방법은 닦음에서 온도 $80^{circ}C$, $110^{circ}C$, $230^{circ}C$, 처리 시간은 6분, 10분, 14분, 데침 $100^{circ}C$에서 1분, 2분, 5분, oven 건조 ($50^{circ}C$)는 5분으로 하였다. 정유함량은 대조군인 생쑥에서 가장 높았고 다음이 덖음의 낮은 온도 짧은 처리 시간에서 높게 나타났다. 가장 많이 나타난 정유 성분은 eucalyptol, cyclohexadience, phenol, terpineol, caryophyllene.이다.
The essential oil obtained by steam distillation from a medicinal plant of Artemisia princeps. The essential oil was analyzed by GC-MS. The heat treatments in roasted condition of temperatures were $80^{circ}C$, $110^{circ}C$, and $230^{circ}C$, and the lengths of the time were 6 min, 10 min, and 14 min, respectively. The blanching conditions($100^{circ}C$) of the treatments lasted 1 min, 2 min, and 5 min while the times of oven dry ($50^{circ}C$) was 5 min. As the result, the essential oil content of the control plot was higher than the others, and that of the roasted ones was the second highest in low temperature with short treatment time. The major components were eucalyptol, cyclohexadience, phenol, terpineol, and caryopbyllene.
