云杉精油的成分分析

ANALYSIS OF CHEMICAL CONSTITUENTS OF ESSENTIAL OIL FROM PICEA ASPERATA MAST

云杉(Picea asperata Mast)主要产于我国西南高山林区,资源丰富,针叶富含挥发油,香味浓郁,至今尚未开发利用。本实验利用水蒸汽蒸馏法提取挥发油,总挥发油经脱水后用毛细管气相色谱分离,气相色谱-质谱-计算机联用和气相色谱-红外-计算机联用技术分析,对其化学成分逐个鉴定。从分离出的约70个可见峰中,鉴定出38个成分,并对各种成分进行定量测定。鉴定出主要成分有莰烯,β-蒎烯,γ-萜品烯,樟脑,龙脑等。

The components and contents of essential oil of Picea asperata Mast. were examined by GC-MS-COM. and GC-IR-COM. 38 components have been identified, including 11 monoterpenes, 7 sequiterpenes and 15 oxygenated compounds. Main components are β-pinene, camphene, camphor, borneol, bornyl acetate.
