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15.94%、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。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 IH NMR were carried out.
