| 摘 要： | “土法”提取精油因其设备简单、拆装方便、容易运输、易操作、成本低等特点，在偏远农村广泛使用，本试验对“土法”水蒸汽蒸馏方法提取精油进行化学成份的GC／MS分析．共分出71个色谱峰．采用GC峰面积归一化法进行定量，其中鉴定出47个化合物，占该精油总量的91．8％。其主要成分为α-柏木烯（22．4％）、柏木醇（20．07％）、α-松油醇（4．29％）、α-蒎烯（2．26％）等．本试验为更好的利用“土法”提取杉木屑精油提供参考，为改进“土法”提取设备提供可靠依据。

| Abstract: | The indigenous extraction method of essential oil was widely used in the remote countryside due to its superiority such as simple devices, convenient to disassemble, transport and manipulate. The chemical compositions of the essential oil extracted by the indigenous method was analyzed by GC/MS,47 constituents were identified from 71 chromatographic peaks, and the relative content up to 91.8%. The major constituents were α-cedrene（22.4%）, cedrol（20.07%）, α-terpineol（4.29%）and α-pinene（2.26%）. This result provided reference for the further usage of the Cunninghamia lanceolata essential oil and improving the extraction equipment. |
