摘要: 
本研究探討以水蒸餾法及頂空間氣相層析(Headspace-GC) 等二方法萃取柳杉(Cryptomeria japonica D. Don)各部位精油,分析其組成化合物及收率,並評估各精油之抗氧化活性。由水蒸餾法取得之葉、心材、邊材、枝條及樹皮精油,分別鑑定出53、44、50、87 及60 個化合物,而以Headspace-GC取得之各部位揮發性化合物,分別鑑定出38、35、46、61 及46 個化合物,且其主成分及收率均與水蒸餾法所得之精油相若。葉精油主要組成分為kaurene (19.1

Both hydrodistillation and headspace-GC methods were applied to extract essential oils
from leaves, heartwood, sapwood, twig, and bark of Cryptomeria japonica D. Don and their chemical
compositions determination and oil yields were analyzed. The
