杉木根精油化学成分研究

Studies on Chemical Constituents of the Essential Oil from the Root of Cunninghamia Lanceolata

采用常压水蒸气蒸馏法提取了杉木根精油 ,用GC、IR、NMR、GC MS等方法对该油进行了定性定量分析 .在分出的 112个色谱峰中共鉴定出 52个化合物 ,占该精油总量的96 .87% .其中含有α 蒎烯、柠檬烯、对伞花烃、α 松油醇、α 柏木烯、α 白菖烯及 β 榄香烯等 ,其主要成分为柏木醇 (39.4 8% ) .

In this paper,root of Cunninghamia lanceolata have been determined by steam distillations,in which the essential oil amounts to 1.9%～2.3%.The essential oil with specific mass 0.858 0～0.871 0,refractive index (20 ℃) 1.474 5,specific rotatory power +0.5 ,also have been determined by classical ways.Chemical constituents of the essential oil from the root of Cunninghamia lanceolata analysed by the aid of GC,GC/MS/DS,IR,NMR and other methods are reported,52 components have been identified.The principal constituents of the essential oil were cedar camphor (39.48%),α pinene,limonene,p cymene,α terpineol,α cedrene,α acorene,β elemene etc.The total content of the above 52 compounds is 96.87% of the essential oil.
