摘要： 本实验先通过水蒸气蒸馏后减压蒸馏法,从杉木根干馏油中分段提取出杉木精油,并用GC、GC-MS对提取物进行了定性定量分析.分离出30个色谱峰,共鉴定出25个化合物.其中,水蒸气蒸馏部分的精油中主要含α-蒎烯11.88%、α-松油醇3.97%、α-柏木烯35.03%、β-柏木烯8.62%、柏木脑11.76%;减压蒸馏部分的精油中主要含α-柏木烯18.02%、β-柏木烯15.04%、柏木脑52.51%,精油经重结晶提纯得柏木脑,并对其进行了红外光谱和核磁共振氢谱分析.

Abstract: The essential oil of Cunninghamia lanceolata(Lamb.) Hook. was obtained by steam distillation first, then by vacuum distillation from the pyroligneous oil of C. lanceolata root,and analyzed qualitatively and quantitatively by GC and GC-MS.From 30 chromatographic peaks, 25 compounds had been identified,which accounted to 96.65% in the steam distillation part, and 95.56% in the vacuum distillation part, respectively. In the former distillate, the main components are α-pinene 11.88%, α-terpineol 3.97%, α-cedrene 35.03%, β-cedrene 8.62% and cedrol 11.76%; In the latter distillate, the main components are α-cedrene 18.02%, β-cedrene 15.94% and cedrol 52.51%. Finally purification of cedrol via recrystallization,and its analysis by IR and 1H NMR were carried out.

Key words: Cunninghamia lanceolata (Lamb.)Hook.root, pyroligneous oil, α-cedrene, β-cedrene, cedrol
